AI agents meant to replace Meta workers made “large-scale, disruptive actions”

Earlier this year, Meta created a “plan” to reduce some of its teams by as much as 60 percent to make the company “AI native,” <a href="https://www.reuters.com/investigations/mark-zuckerberg-had-bold-plan-replace-meta-staff-with-ai-heres-how-it-imploded-2026-08-26/">Reuters</a> reported today, citing two people familiar with Meta’s internal affairs.

And to explain just what a bimodal nuclear rocket is, and why the new version we have conceived together brings it closer to future reality, we first need to take a quick trip to the past.<a href="https://files.eric.ed.gov/fulltext/ED054967.pdf" rel="noopener noreferrer" target="_blank">As early as 1946</a>, researchers realized that nuclear reactors had the potential to become extremely efficient thermal rocket engines. Most rockets are thermal rockets, and they work by expelling hot gases through a nozzle, thrusting the rocket forward. While there are other factors such as nozzle shape, generally speaking, the hotter and faster you make the rocket’s exhaust gases, the more acceleration the rocket will produce for a given mass of propellant. Because a smaller molecule will move faster than a larger one when heated to a given temperature, the smaller the molecular mass of your propellants, the better. By convention, the efficiency of a rocket engine is measured by how long the engine can exert a thrust equal to the initial weight of its propellant, a quantity known as specific impulse.In a conventional thermal rocket, such as those used in every launch to orbit since Sputnik, the exhaust temperature and speed—and thus the specific impulse—is dictated by the energy released by a chemical reaction and the mass of the reaction’s by-product. The most efficient chemical rockets today combust hydrogen with oxygen, producing water and a specific impulse that tops out around 450 seconds.But a nuclear rocket is not limited by chemistry. The heart of a nuclear thermal rocket is a nuclear fission reactor, in which chain reactions in uranium fuel release much more energy per kilogram than is possible with chemical combustion. A turbopump forces liquid hydrogen alone—with its very small molecular mass—through the reactor’s core, heating it to temperatures of at least 2,700 kelvin before expelling it, resulting in a specific impulse of 900 seconds or more.In the 1950s and 1960s, the <a href="https://losalamoshistory.org/synder-even-though-it-never-flew-project-rover-changed-history/" rel="noopener noreferrer" target="_blank">Rover</a> and <a href="https://www1.grc.nasa.gov/wp-content/uploads/NERVA-Nuclear-Rocket-Program-1965.pdf" rel="noopener noreferrer" target="_blank">NERVA</a> (Nuclear Engine for Rocket Vehicle Applications) programs <a href="https://spectrum.ieee.org/the-national-atomic-testing-museum-come-for-the-nukes-stay-for-the-test-and-measurement" target="_self">ground-tested</a> nuclear thermal rockets. By the early 1970s, <a href="https://www.nasa.gov/rocket-systems-area-nuclear-rockets/" rel="noopener noreferrer" target="_blank">the technology had matured</a> to the point where<a href="https://ntrs.nasa.gov/api/citations/19910017902/downloads/19910017902.pdf" rel="noopener noreferrer" target="_blank"> flight tests were being planned</a>. But changing political and budgetary winds led to nuclear thermal development being shut down in 1973.Another prong of nuclear propulsion that has also demonstrated considerable promise is nuclear electric propulsion. In <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/What_is_Electric_propulsion" rel="noopener noreferrer" target="_blank">electric propulsion</a>, instead of creating a stream of hot rocket exhaust through chemical reactions or exposure to the core of a nuclear reactor, electricity is generated and used to create electromagnetic fields that accelerate an ionized propellant such as xenon or lithium.Various schemes to do this exist, including some that have already seen considerable time in space, such as the ion thrusters used on the <a href="https://science.nasa.gov/mission/dawn/technology/ion-propulsion/" rel="noopener noreferrer" target="_blank">Dawn asteroid mission</a> launched in 2007. So far, these electric thrusters have only been powered by solar panels. But with a nuclear reactor as part of a power plant that supplies the juice, more thrust could be produced. And moving beyond solar power is particularly important in missions to the outer solar system where sparse solar photons would require enormous solar arrays.With electric thrusters, specific impulses in the range of <a href="https://esamultimedia.esa.int/docs/Aurora/execsummaries/Assessments_of_electrical_propulsion_systems_for_exploration_missions.pdf" rel="noopener noreferrer" target="_blank">2,200 to 4,600 seconds</a> are possible, but currently with very low thrust. With the energy available to a nuclear-powered electric propulsion engine, you could have greater acceleration and reduced mission times. The nuclear reactor could also provide electrical power for all the spacecraft systems as well.The <a href="https://www.energy.gov/etec/system-nuclear-auxiliary-power-snap" rel="noopener noreferrer" target="_blank">System for Nuclear Auxiliary Power</a> (SNAP) program launched the SNAP-10A in 1965 as a proof of concept, the first—and so far only—U.S. nuclear power reactor in space. It generated about 600 watts of electrical power for 43 days before shutdown and is still in orbit. Subsequent U.S. initiatives for more substantive electric power and nuclear thermal propulsion systems, such as the <a href="https://ntrs.nasa.gov/api/citations/19870013594/downloads/19870013594.pdf" rel="noopener noreferrer" target="_blank">SP-100</a>, <a href="https://en.wikipedia.org/wiki/Project_Timberwind" rel="noopener noreferrer" target="_blank">Project Timberwind</a>, and <a href="https://ui.adsabs.harvard.edu/abs/2007AIPC..880..497A/abstract" rel="noopener noreferrer" target="_blank">Project Prometheus</a>, along with more recent projects like Demonstration Rocket for Agile Cislunar Operations (<a href="https://www.darpa.mil/research/programs/demonstration-rocket-for-agile-cislunar-operations" rel="noopener noreferrer" target="_blank">DRACO</a>) and Joint Emergent Technology Supplying On-Orbit Nuclear (<a href="http://jetson" rel="noopener noreferrer" target="_blank">JETSON</a>), have emerged sporadically over the years. None of these have yet progressed to actual flight.However, space nuclear power got a huge shot in the arm in March 2026 when NASA Administrator <a href="https://www.nasa.gov/people/jared-isaacman/" rel="noopener noreferrer" target="_blank">Jared Isaacman</a> announced <a href="https://www.nasa.gov/news-release/nasa-unveils-initiatives-to-achieve-americas-national-space-policy/" rel="noopener noreferrer" target="_blank">a new space exploration initiative</a>. As part of that initiative, the agency plans to launch Space Reactor-1 Freedom (SR-1) to deliver a trio of robot-survey helicopters to Mars. Driven by nuclear electric propulsion, SR-1 aims to demonstrate fission technology in deep space and would be the first nuclear-powered interplanetary spacecraft, <a href="https://www.nasa.gov/mission/space-reactor-1-freedom/" rel="noopener noreferrer" target="_blank">generating 20 kilowatts of electric power</a> aboard.This is a bold step for NASA, and brings us up to the present, but the details of the proposed mission also highlight a familiar limitation of nuclear electric propulsion. Even with improved acceleration, electric propulsion still cannot generate the powerful bursts of thrust needed to escape gravity wells, such as those of Earth or Mars, or perform time-critical maneuvers, like course corrections. On the other hand, while not as efficient and unable to supply electrical power for spacecraft systems, nuclear thermal engines are great at delivering high thrust at critical moments.<h2>What is a bimodal nuclear rocket?</h2>Some engineers would suggest we build two separate systems—one reactor for thermal propulsion and another reactor for power and electric propulsion. But since <a href="https://ntrs.nasa.gov/api/citations/19990019002/downloads/19990019002.pdf" rel="noopener noreferrer" target="_blank">at least the 1990s</a>, it has been the dream of many engineers to combine nuclear thermal and nuclear electric in one package, with one reactor: the bimodal nuclear rocket.Most previous bimodal proposals depend on complex valve arrangements to integrate the propulsion and power systems. In thermal propulsion mode, the reactor is brought to maximum activity by a set of control drums that ring the core, which is composed of a matrix of long uranium-fuel elements. The drums take the shape of long cylinders made of beryllium, with a 120-degree segment of each cylinder covered with boron carbide. Boron absorbs neutrons, and when that segment faces the reactor, the reactor’s activity is low as neutrons escaping from the core are captured. Rotating the boron segment so that it faces away from the core (leaving only the beryllium exposed) increases nuclear activity as the beryllium reflects escaping neutrons back into the core’s fuel elements, where they can contribute to chain reactions. <img alt="A diagram showing a squashed elliptical transfer path between Earth and Mars and back again" class="rm-shortcode" data-rm-shortcode-id="b74aed259e91b149250d79d80a042bbb" data-rm-shortcode-name="rebelmouse-image" id="8b8fa" loading="lazy" src="https://spectrum.ieee.org/media-library/a-diagram-showing-a-squashed-elliptical-transfer-path-between-earth-and-mars-and-back-again.png?id=67669299&width=980"/> This proposed trajectory, developed at NASA’s Glenn Research Center, shows where high-thrust maneuvers [blue dots] are executed by a nuclear thermal engine and additional low-thrust, high-efficiency acceleration and deceleration is performed by electric propulsion [hashed lines show thrust direction]NASA Glenn Research CenterOnce the reactor is generating large amounts of heat, liquid hydrogen is pumped through channels that run the length of the core. Turned into an expanding hot gas, the hydrogen blasts from the other end of the core to form the rocket’s powerful exhaust.In nuclear power mode, the reactor’s activity is damped. Valves seal the channels and a so-called power-conversion fluid—typically a mixture of helium and xenon gas—circulates through the reactor in a closed loop. The reactor is still hot enough to warm this fluid, which drives a turbine connected to an electrical generator.The key point here is that a single set of flow channels and nuclear-fuel elements are used for both modes. But the valves used to switch modes face the formidable challenge of enduring months, or even years, in a harsh radiation environment while maintaining leak-tight performance. <img alt="A diagram of a core composed of an hexagonal array of red and blue fuel elements surrounded by a cylinder embedded with a ring of smaller cylindrical drums." class="rm-shortcode" data-rm-shortcode-id="1f36f39faee86d47ce0ffe2e1d9b4497" data-rm-shortcode-name="rebelmouse-image" id="3136c" loading="lazy" src="https://spectrum.ieee.org/media-library/a-diagram-of-a-core-composed-of-an-hexagonal-array-of-red-and-blue-fuel-elements-surrounded-by-a-cylinder-embedded-with-a-ring-o.png?id=67676152&width=980"/> The core’s activity is controlled by the rotating drums surrounding it. Within the core, low-temperature fuel elements [left in blue, and top right] produce electric power by heating a circulating fluid. High-temperature fuel elements [left in red, and bottom right] heat hydrogen as a propellant. (The taper of the HTFE’s exhaust channel is exaggerated for illustrative purposes. Ways of packaging the HTFE’s uranium fuel other than with particles are possible.)John MacNeillIn addition, the nuclear-fuel elements surrounding the channels must be able to operate for short durations at very high temperatures during thermal thrust maneuvers and for long durations at lower temperatures during the rest of the voyage. It is difficult to build one type of element capable of both. Hence, the complexity and demanding engineering requirements of previous bimodal designs has hindered their practical application.We propose a simplified approach, a hybrid system we call the synchronal bimodal nuclear rocket (S-BNR). The genesis for this design came about when we were attending a conference together in 2025. One of us (Polzin) had an initial idea, and in time-honored tradition, he sketched it out on a napkin to see if the other (Schleicher) thought there was actually a way to do it. We’ve been working on refining the concept ever since.<h2>How the synchronal bimodal nuclear rocket works</h2>Rather than relying on a complex valve system, the S-BNR uses two hydraulically independent loops within a single reactor core, one open loop (for thermal propulsion) and one closed loop (for electrical power). The core is divided into two zones, one per loop, differentiated by the type of fuel elements in each. Several designs for the fuel elements are possible: In our preliminary design, the high-temperature fuel elements (HTFEs) in the thermal propulsion zone consist of a bed of “pebbles”—uranium fuel encased in zirconium carbide—that surround a central tapering channel and operate at greater than 2,700 K. (One possible alternative for the HTFEs would be a solid fuel design, as with NERVA.) The hydrogen propellant passes through the pebble bed, where the pebbles’ large surface area maximizes the transfer of heat needed for efficient high-thrust propulsion.The other zone has low-temperature fuel elements (LTFEs), optimized for long-term, efficient production of electricity, which can range from tens of kilowatts to several megawatts. In these elements, the uranium fuel in solid form surrounds a double-walled channel: The power-conversion fluid is pumped down the inside and returns along the outside wall, absorbing heat from the fuel and operating at moderate temperatures (at or above 1,200 K). <img alt="A block diagram showing the fluid flow with the reactor core." class="rm-shortcode" data-rm-shortcode-id="b3fb5eae20fb11c97ada403d166baf59" data-rm-shortcode-name="rebelmouse-image" id="26098" loading="lazy" src="https://spectrum.ieee.org/media-library/a-block-diagram-showing-the-fluid-flow-with-the-reactor-core.png?id=67676153&width=980"/> The electric-power and nuclear-thrust elements of the core have separate fluid loops, which eliminates the need for valves to switch between closed-loop operation for power generation and open-loop operation for propulsion.John MacNeillBoth the HTFEs and LTFEs contribute the neutrons required to sustain chain reactions. In power-only mode, residual heat moves from the HTFEs into adjoining LTFEs. The physical interface between the elements is designed to moderate this thermal flow to balance two competing needs: It must allow enough heat flow to safely remove the residual heat from the HTFEs, but it must also limit that heat flow so the LTFEs’ temperatures do not go past their allowable limits when the HTFEs operate at high power.During combined propulsion and power operation, a heat exchanger on the power loop preheats the hydrogen propellant for the thrust loop, aiding the turbopump that feeds the hydrogen through the core. After a propulsion burn is completed and the HTFE chain reactions are damped by the control elements, the power loop removes residual-decay heat coming from the HTFEs as described above, eliminating the requirement in earlier designs for additional propellant flow just to cool down the core while on standby. This dual-loop system also means the engine can produce high thrust whenever needed while allowing the generator to remain active at all times—a significant advantage for crewed missions.By adopting this dual-loop architecture, the S-BNR removes the need for the problematic mode-switching valves found in earlier concepts. Each fission zone is constructed with materials tailored to its specific temperature and power requirements, ensuring optimal performance and durability. The result is uninterrupted electrical power across all mission stages, making it unnecessary to carry additional liquid hydrogen just to manage decay heat.<h2>The challenges ahead</h2>While significant progress in developing the design of the S-BNR has been made, substantial challenges remain. The reactor must maintain stable control across a wide power range, from modest levels for electricity generation to hundreds of megawatts of thermal power during high-thrust operation. Operating the power-generation loop in close proximity to the HTFEs requires very careful management of both temperature and the neutrons emitted by the fuel elements.And crucially, demonstrating reliable, long-duration performance is particularly demanding: Missions to Mars may require years of continuous power generation. Outer-planet probes equipped with S-BNR engines could extend that to a decade or longer.In the past, nuclear thermal propulsion fuel elements were engineered for extremely high temperatures but only brief operational lifetimes (typically hours), whereas proposed nuclear electric propulsion fuel elements are optimized for lower temperatures and intended to last for years. By using two different types of fuel elements in the S-BNR, we can take advantage of the design heritage of both these development tracks. Fortunately, recent NASA-sponsored research has produced several promising candidates that may meet these demanding requirements.Ground-testing these systems is also a challenge. Early in the Rover and NERVA era, the exhaust from test engines was blasted into the atmosphere, something now unacceptable. Today, any ground test of an engine must completely capture all potentially radioactive exhaust products. Fortunately, <a href="https://ntrs.nasa.gov/api/citations/20140008803/downloads/20140008803.pdf" target="_blank">a number of approaches </a>have been developed to capture and scrub the exhaust, although these methods currently carry a significant price tag.Then there is the ultimate test: flying an S-BNR in space. International regulatory and safety protocols for nuclear launches were developed largely in response to the Soviet Union’s launch of dozens of nuclear-powered Radar Ocean Reconnaissance Satellite (RORSAT) radar spy satellites in the 1970s and 1980s. There were a number of incidents, with the most serious leaving <a href="https://www.cia.gov/readingroom/docs/COSMOS%20954%2C%20CRASH%20OF%20A%20RO%5B15826354%5D.pdf" target="_blank">radioactive debris</a> strewn across a swath of Canada in 1978. This history led to a consensus in the space community that might be summarized as “Thou shalt not bring a nuclear reactor to criticality in any Earth orbit that decays faster than dangerous isotopes.”Thus any S-BNR would be launched atop a conventional chemical rocket, with a completely cold reactor and fresh fuel. Fresh uranium fuel is not in fact very radioactive: The potentially larger concern is the chemical toxicity of this heavy metal, but it can easily be handled by wearing light protective suits, respirators, and gloves. Only after the control elements have been adjusted to permit chain reactions to begin within the core are highly radioactive isotopes able to form from fission fragments. There would be even less cause for concern than when launching a radioisotope thermoelectric generator (RTG), such as the sort that are currently powering the <a href="https://science.nasa.gov/mission/mars-2020-perseverance/rover-components/#power" target="_blank">Perseverance rover on Mars</a> and the <a href="https://science.nasa.gov/resource/new-horizons-radioisotope-thermoelectric-generator/" target="_blank">New Horizons</a> mission in the outer solar system.Even in the most extreme scenario imaginable—the chemical booster explodes and somehow damages the reactor’s control elements in just the right way to initiate a chain reaction—there wouldn’t be time to produce a large amount of toxic isotopes before the reactor broke apart and reactions ceased. (We can be sure of this because Project Rover actually tested this kind of worst-case scenario in 1965 with the <a href="http://large.stanford.edu/courses/2014/ph241/wendorff1/docs/la-3449.pdf" target="_blank">Kiwi-TNT test</a>, where an engine prototype was rigged to produce a runaway chain reaction sufficient to vaporize the reactor core due to the immense internal pressure buildup. Negligible radiation spread outside a radius of two miles (3.2 kilometers), well within the range of safe distances for launching any rocket capable of reaching orbit, and site decontamination was possible after only a few days of radioactive decay.)Despite all these considerable engineering challenges, the foundation laid by decades of investment in nuclear thermal and electric propulsion and terrestrial nuclear power technologies provides a solid platform for continued advancement. Indeed, much of the foundational work is already underway through ongoing NASA and<a href="https://www.spaceforce.mil/" rel="noopener noreferrer" target="_blank"> U.S. Space Force</a> efforts. <img alt="A boxy spacecraft with large solar cells flies through space, propelled by a blue exhaust from a thruster.

Near-term non-nuclear testing will validate fluid loop operation, heat transfer mechanisms, and control strategies. Next, component-level irradiation and thermal trials will qualify new materials. Then, integrated reactor testing will begin, first without nuclear fuel and later with fueled reactors undergoing fission. Finally, initial in-space demonstrations could begin with lower-power systems, eventually scaling up to full bimodal capabilities.Achieving success will require close collaboration across NASA, the Department of Energy, the Department of Defense, industry partners, and the broader technical community. Progress will depend on advancements in high-temperature fuels and materials, improved systems for power conversion and heat transport, and the adoption of innovative manufacturing techniques and methods to control nuclear fission over a wide range of output power. In particular, integrated system testing will be more complex than previous programs such as NERVA, due to the combined functions and distinct operational regimes for thermal propulsion and power generation. We hope engineers and researchers with relevant expertise will be encouraged to contribute to addressing these challenges, whether in the areas of thermal management, reactor modeling and control, extended-duration testing, or safety analysis.Past ground tests and limited demonstrations have already established the capabilities of space nuclear systems. With architectures like the synchronal bimodal nuclear rocket, the prospect of integrating high-thrust propulsion and sustained power generation becomes increasingly practical and versatile. The next phase is not simply about traveling fast. It’s about building crewed and uncrewed spacecraft that can reliably travel to destinations throughout the solar system that are currently difficult or impossible to reach, with missions potentially lasting years or even decades.

AI Companion Robots Are Closing the Human Connection in Modern Homes

<img src="https://spectrum.ieee.org/media-library/cute-home-robot-on-carpet-in-cozy-living-room-with-beige-sofa-and-warm-lighting.jpg?id=67154308&width=1245&height=700&coordinates=0%2C260%2C0%2C261"/> This article is brought to you by <a href="https://ollobot.com/" target="_blank">Ollobot</a>.From about 2017, individuals began to truly connect with the initial wave of companion robots. These devices had personality, moved around, joked, and answered when you spoke to them. Most early companion robots, however, were still limited by simple voice-command interactions and narrow functionality. Once the novelty wore off, many ended up sitting unused on shelves. As some of those companies went out of business and turned off their servers, many owners likened it to losing a pet.What Ollobot describes as “gentle intelligence” is a useful way to think about where the serious work in this category is going. Not toward more powerful assistants, but toward more present ones.<h2><a target="_blank"></a>The problem companion robots were trying to solve</h2>Loneliness is not a niche issue. According to one <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9957792/" target="_blank">study</a>, nearly one out of three elderly adults resides alone, meaning they do not have daily companions. <a href="https://pubmed.ncbi.nlm.nih.gov/20533912/" target="_blank">Research</a> also shows that children whose parents have migrated for work, leaving them in the care of relatives, were 2.5 times more likely to experience loneliness than children whose parents remain with them. Among working adults living alone in urban environments, similar <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6530780/" target="_blank">patterns</a> of social isolation emerge, even if they are less visible.Over the years, technology has time and again attempted to solve this problem via video calls, smart speakers, and messaging apps without much success. Those tools are geared towards communication between people that already have relationships. They do not create presence. They schedule it. That is the gap that a new generation of AI companion robots is being engineered to fill.<h2><a target="_blank"></a>Today’s AI robots are different</h2>Today’s companion robots are not just cute and cuddly. They are designed with psychological research, clinical insight and long-term interaction models to be truly useful in real homes.Three fundamental shifts define the current generation:<ol><li>From reactive to proactive response. Older robots relied on you speaking to them, but modern robots monitor a room with cameras, microphones, and surroundings sensors to initiate interactions without your input, and they can pick up on your emotions.</li><li>From function-oriented to emotion-oriented design. The original pitch for companion robots was about what they could do. The question driving the serious work now is how they make you feel, which is a harder engineering problem and a more honest framing of what the product is actually for.</li><li>From standalone hardware to connected ecosystems. Leading brands are creating platforms rather than devices with software included as a built-in layer and remote access from the beginning.</li></ol>The <a href="https://www.grandviewresearch.com/industry-analysis/ai-companion-market-report?__cf_chl_f_tk=xJq0xhwCGb6n830sK3lMN.cyk2m73bms6.RauBufPho-1783406928-1.0.1.1-TsUMt2nxUgZ5nDX79zhxxVYkTv9xk2r_.E2rbXRHByA" target="_blank">global AI companion market</a> size was valued at US $36.8 billion in 2025 and is projected to grow from $48 billion in 2026 to $318 billion by 2033, at a compound annual growth rate of 31 percent from 2026 to 2033. <h2><a target="_blank"></a>Three household scenarios and interaction models</h2>Ollobot’s advanced AI family companion robot <a href="https://ollobot.com/" target="_blank">OlloNi SS1</a> addresses a number of gaps in what existing technology offers.Elderly individuals living alone. The combination of proactive interaction, fall detection, and persistent presence addresses both safety and companionship without the social overhead of asking family members to check in more frequently.Children in households where parents work far from home. The SS1 functions as a consistent companion that already knows a child, their preferences, their moods, and their routines. The remote connection features allow parents to stay present without requiring a scheduled call, and the life recording system gives them a passive window into their child’s days that feels less clinical than a monitoring camera.Single professionals living alone in cities. The SS1 adapts to daily routines, builds up a preference model over time, and provides ambient social presence without demands. <img alt="Cute home robot with a purple cover and cartoon face displayed on its screen." class="rm-shortcode" data-rm-shortcode-id="bd8ec4a867547204437967b3f231338f" data-rm-shortcode-name="rebelmouse-image" id="8d48b" loading="lazy" src="https://spectrum.ieee.org/media-library/cute-home-robot-with-a-purple-cover-and-cartoon-face-displayed-on-its-screen.jpg?id=67154351&width=980"/> OlloNi SS1 adapts to daily routines over time.Ollobot<h2>What OlloNi SS1 is doing differently?</h2>Ollobot’s goal in building intelligent companion robots is to address the gaps in technology and capability, using innovation not to automate tasks but to fill emotional voids.Much of the robotics industry has historically pursued human imitation — machines that speak, look, or behave like people. The SS1 is instead designed around familiarity and long-term coexistence rather than realism.The system integrates multiple subsystems operating in parallel, including visual perception, audio processing, mobility control, and interaction management. It is equipped with a multi-chip AI 4K vision module capable of facial recognition and motion tracking. One small but revealing detail is the inclusion of a physical privacy cover for the camera — a mechanical solution to concerns that software settings alone may not fully resolve. <img alt="Person playing with a red plush robot toy that has a glowing digital face and eyes" class="rm-shortcode" data-rm-shortcode-id="b39299c23f2f658c0a0284c5803d36ae" data-rm-shortcode-name="rebelmouse-image" id="daa03" loading="lazy" src="https://spectrum.ieee.org/media-library/person-playing-with-a-red-plush-robot-toy-that-has-a-glowing-digital-face-and-eyes.jpg?id=67154349&width=980"/> OlloNi SS1 can actively integrate into family activities, and it can autonomously move closer to capture memorable moments or reposition itself to remain engaged in ongoing interactions.OllobotThe robot supports advanced mobility across multiple indoor surfaces, including wooden floors, ceramic tiles, and low-pile carpets, with slope climbing capability up to 3.5 degrees. Rather than remaining in a fixed location, it can move naturally throughout the home to stay close to household members as daily activities unfold. For example, the OlloNi SS1 may greet family members when they arrive home, follow an older adult from the living room to the kitchen while continuing a conversation, remind a child to take a study break after a prolonged period of inactivity, or notice that someone appears unusually quiet and gently check in. During family activities, it can autonomously move closer to capture memorable moments or reposition itself to remain engaged in ongoing interactions.The robot continues to evolve over time, with over-the-air updates that deliver new features, performance improvements, and AI enhancementsIt also incorporates fall detection with optimized accuracy for safety monitoring scenarios. A 6-microphone array enables omnidirectional voice pickup with an effective voice capture range of up to 5 meters, supporting reliable wake-word detection and far-field interaction.To support continuous companionship, much of the robot’s AI processing takes place directly on the device through its “heart module” architecture, with 16 GB of memory and 64 GB of local storage. This enables the system to retain household memories, recognize familiar faces, and respond with lower latency, making interactions feel more natural even during everyday routines.Because companion robots are expected to remain available throughout the day rather than only during brief interactions, the SS1 is designed for extended operation, offering up to 12 hours of standby time and around 5 hours of active interaction on a single charge. This allows it to accompany users through meals, conversations, playtime, and other daily activities without frequent interruptions. <img alt="Close-up of toy robot with glowing red heart and purple fur on a beige body." class="rm-shortcode" data-rm-shortcode-id="ad4e47da5ac276c65c47c13fb8cbd4a2" data-rm-shortcode-name="rebelmouse-image" id="0261b" loading="lazy" src="https://spectrum.ieee.org/media-library/close-up-of-toy-robot-with-glowing-red-heart-and-purple-fur-on-a-beige-body.jpg?id=67154317&width=980"/> To support engaging interactions, much of the robot’s AI processing takes place directly on the device through its “heart module” architecture.OllobotLike the relationships it is designed to build, the robot continues to evolve over time. Running on Android OS with over-the-air (OTA) updates, the system continuously receives new features, performance improvements, and AI enhancements, allowing its capabilities to grow alongside the household it serves.The robot’s behavioral model also improves over time. Rather than reacting to isolated commands, it attempts to establish a baseline understanding of household routines and individuals. Changes in behavior — prolonged quietness, unusual inactivity, or emotional cues — become triggers for interaction.<h2>Presence instead of utility</h2>Several features in the OlloNi SS1 illustrate this emphasis on presence and continuity in its interactions.The system can identify different household members, including pets, and adapt responses accordingly. Remote communication features allow family members to connect through the device without treating every interaction like a scheduled call. Environmental sensors support contextual reminders tied to weather or room conditions.Its “2+1” multi-display configuration is also designed around emotional communication. Two circular side displays function as expressive “emotional eyes,” while a separate primary display handles information and structured interaction. The separation allows emotional signaling and functional communication to operate independently, creating more intuitive nonverbal interaction even when no dialogue is taking place. <img alt="Cute red robot pet in checkered shirt sits on rug in cozy, warmly lit living room" class="rm-shortcode" data-rm-shortcode-id="f177ff7ea3f02aacf9e12a93a6b7e445" data-rm-shortcode-name="rebelmouse-image" id="5f2a7" loading="lazy" src="https://spectrum.ieee.org/media-library/cute-red-robot-pet-in-checkered-shirt-sits-on-rug-in-cozy-warmly-lit-living-room.jpg?id=67154312&width=980"/> The robot’s behavioral model improves over time. Rather than reacting to isolated commands, it attempts to establish a baseline understanding of household routines and individuals.OllobotThe SS1 also includes an automated life-recording system built on facial recognition and behavioral-event detection that can capture moments such as laughter, physical closeness, or group interaction automatically. An integrated AI vlog engine can then organize those moments into edited short-form videos with automated sequencing and soundtrack generation. The design intent is to preserve spontaneous domestic moments without requiring active documentation behavior from users.An integrated AI vlog engine can organize recorded moments into edited short-form videos with automated sequencing and soundtrack generationVisual data is processed primarily on the device through the SS1’s on-device AI architecture, with household memories stored locally and managed within Ollobot’s proprietary ecosystem instead of being shared with third-party smart home platforms. Access to recordings and live feeds is restricted to authorized users through the companion app, while encrypted communication helps protect data during remote access. Users also retain direct control over recording preferences, and the physical camera privacy cover provides an additional hardware-level safeguard whenever visual monitoring is not desired.<div class="ieee-sidebar-small"> <img alt="Ollobot logo with circular icon and bold lowercase text on light background" class="rm-shortcode" data-rm-shortcode-id="c161d66f60be15a6d25fa8fcac7ad1d7" data-rm-shortcode-name="rebelmouse-image" id="8eca7" loading="lazy" src="https://spectrum.ieee.org/media-library/ollobot-logo-with-circular-icon-and-bold-lowercase-text-on-light-background.png?id=67154360&width=980"/>Learn more at <a href="https://ollobot.com/" target="_blank">ollobot.com</a>.</div>Remote communication is similarly structured around persistence rather than transaction. Traditional video calls are episodic and screen-bound; the SS1 instead acts as a continuously present interface embedded inside the household environment. Through autonomous mobility, environmental awareness, and persistent household memory, remote family members interact with an ongoing domestic context.<h2><a target="_blank"></a>The larger shift to “gentle intelligence”</h2>Ultimately, gentle intelligence is not about making robots behave more like humans — it is about helping them fit more naturally into human lives. Each OlloNi SS1 unit develops a unique behavioral profile based on its household. Two units running in different homes for a year will have become meaningfully different from each other, shaped by the specific people, habits, and rhythms of where they live.That kind of long-term personalization is what early companion robots never had. It is also what makes the difference between a product that ends up on a shelf and one that actually earns its place in a home.Learn more at <a href="https://ollobot.com" target="_blank">ollobot.com</a>.

Inaudible sounds used to fingerprint browsers catch AliExpress red-handed

Chinese retailer AliExpress has been caught fingerprinting visitors after one of the metrics—an outdated technique that measures inaudible sounds it sends to browsers—impeded a researcher's ability to use his bluetooth headphones. Researcher Matthew Callaghan <a href="https://blog.laserphile.com/2026/08/aliexpress-webpage-keeping-multipoint.html">said</a> he stumbled on the stealthy tracking by mistake. After loading the AliExpress homepage, audio from his phone stopped playing over his multipoint headphones, which accept connections from more than one device at a time. He set the headphones to play sounds from his phone except when his PC was producing audio. Each time he loaded AliExpress, the phone audio stopped. Each time he closed the tab the site was loaded into, the phone was once again audible. <h2>Users can't hear it, but browsers can</h2> While investigating the odd behavior, Callaghan said he found two highly obfuscated scripts. Together, they rendered a graph that analyzed the <a href="https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/OfflineAudioContext/explainer.md">WebAudio</a> readings of each visiting browser.

Building Technology People Can Trust

<img src="https://spectrum.ieee.org/media-library/stacked-green-printed-circuit-boards-with-electronic-components-on-a-work-surface.jpg?id=67598440&width=1245&height=700&coordinates=0%2C260%2C0%2C261"/> This article is brought to you by <a href="https://www.emerson.com/en/corporate" target="_blank">Emerson</a>.I’ve spent much of my career as an engineer, including years in the semiconductor industry. And one lesson has stayed with me through every major technology shift: innovation always creates new complexity.In semiconductors, we have seen that repeatedly. Every generation has delivered breakthroughs in performance and capability, but each step forward made it harder to understand system behavior. What used to be easy to validate on the component level with a test bench now needs a much wider view. <img alt="Smiling woman with curly hair in black blazer posing at a table against plain background" class="rm-shortcode" data-rm-shortcode-id="21444500c0ecccd464d7236ab01f4cca" data-rm-shortcode-name="rebelmouse-image" id="1b4da" loading="lazy" src="https://spectrum.ieee.org/media-library/smiling-woman-with-curly-hair-in-black-blazer-posing-at-a-table-against-plain-background.png?id=67603478&width=980"/> “The future of engineering will be defined by who can verify, understand, and improve complex systems fast enough to safely keep innovation moving forward,” says Ritu Favre, President of Emerson’s Test & Measurement business group.EmersonChiplet-based designs are a prime example. A chiplet from one supplier, an interposer from another, and a packaging process from a third may all perform perfectly on their own. Yet there is a chance for unexpected behavior when you put them together in a system. More and more often, the hardest engineering challenges are not in the individual components themselves. The problems are found when we start to combine components and have them interact with each other.These challenges extend far beyond semiconductors. Products are becoming more software-defined and dependent on interactions across different technologies and environments. Think about the interactions needed for a modern car using adaptive cruise control on a bumpy road in a rainstorm. Or a passenger jet adjusting wing flaps and engine speeds in turbulent weather to maintain safety and stability. Both the car and the jet are being guided by complex computer systems with thousands of sensors leading to thousands of interactions every second. And in many cases, there are multiple computer systems working together. We are building systems of remarkable capability but understanding how they will act under real-world conditions is getting harder.That is why I believe we are entering a new era of test. The defining challenge of modern engineering is no longer simply what we can design and build. It is what we can confidently verify.<h2>Rethinking the Role of Test</h2>In this new era, test can’t be an afterthought. For decades, test was treated as the final checkpoint before release. Design teams developed a product, test teams validated performance, and organizations looked for a final pass/fail to determine whether they were ready to move forward. That model worked fine when systems were more self-contained and predictable. Today, that approach can lead to more risk.I believe we are entering a new era of test. The defining challenge of modern engineering is no longer simply what we can design and build. It is what we can confidently verify.Many of the delays and fire drills we face come from issues that were not visible early enough. Problems discovered late in development are more difficult to diagnose, more expensive to fix, and more likely to get you off schedule. The solution is not more testing at the end. The solution is to make test and verification part of the engineering workflow from the start.When validation is integrated throughout development, teams catch problems early when change is easier. Test also stops being a barrier to release. Instead, it becomes a source of insight, helping us understand how systems behave as they become more connected.<h2>Why Connected Platforms Matter</h2>When confidently verifying technology becomes the key challenge, the tools we choose take on a different level of importance. The tools have a direct impact on how quickly we can diagnose a problem and keep moving forward. In an environment where technology changes rapidly, disconnected tools get in the way of progress. Modern test strategy requires linking information across design, validation, and production, turning measurement data into decisions made quickly enough to keep pace with innovation.This reminds me of when EDA was first introduced. Before it came along, engineers spent much of their time hand-drawing circuit layouts and placing transistors. EDA eliminated that tedious work by letting teams describe complex behavior in high-level code. It enabled them to focus on overall architecture instead.A connected test platform does a similar thing for validation. Because a platform can adapt and scale alongside technology, it cuts down on maintenance and downtime, keeping teams from having to rebuild their workflows from scratch as requirements change.<h2>Grounding AI in Engineering Reality</h2>Today, AI is rapidly entering the engineering toolkit to accelerate design and analysis. But in test and measurement, AI cannot reach its potential in isolation.An AI model is only as effective as the data feeding it. Without context, even the smartest algorithm will struggle to tell the difference between normal hardware variance and a critical failure. A connected platform supplies the structured, traceable data stream AI requires to deliver real insight.AI can correlate complex multi-system interactions, flag unexpected behavior, and direct an engineer’s attention right at the root cause.When measurement data flows seamlessly across the workstream, AI moves from being a standalone tool to an active layer of intelligence. It can correlate complex multi-system interactions, flag unexpected behavior, and direct an engineer’s attention right at the root cause.Every technology shift that accelerates how fast we create new designs also increases the complexity we must verify. AI can help teams keep pace with that complexity. Not by replacing human judgment, but by giving engineers the context we need to act with confidence.<h2>Innovation Demands Confidence</h2>Ultimately, the goal of modern platforms and AI-enabled workflows is to help technical teams spend more time building new things and solving hard problems. Most of us didn’t choose this profession to spend our time searching for data or dealing with last minute surprises. We want to innovate and integrating test directly into development provides a better view of system behavior, allowing teams to focus on that innovation rather than managing complexity.The future of engineering will not be defined by who can build the most advanced product or technology. It will be defined by who can verify, understand, and improve complex systems fast enough to safely keep innovation moving forward.That is the new era of test. As the pace of innovation accelerates, every breakthrough creates new paths to failure, and test is how engineers find those failures before the real world does. In an increasingly complex world, that capability is becoming as important as innovation itself.Innovation has always required great engineering. And now, more than ever, it also requires confidence. Confidence that comes from knowing that we are not only building what is possible, but we are also building technology that people can trust. Reference: https://ift.tt/EzKtmxR

Poetry for Engineers: Safe Distance

Optical. Through liquid glass, through flickering light that carries you in fragments. Light broken into pulses. You say: it’s easier this way. What are we missing like this? You smile. Safe distance. I say: network. Signals slide beneath the sea, through cables thinner than trust, faster than touch, slower than longing. We stand alone, together. Synchronous, yet apart. Icons replace skin, latency replaces breath. This distance protects us. Silence that feels intentional. Everything is under control as long as nothing truly hurts. And we choose it because it shields us from what we might become if we actually met. You are my counterpoint. My response. My reflection at a safe distance. Beneath the ocean, nodes remember paths. Packets shake hands without bodies. If we get lost, we resend everything, with error, with noise, with hope. Reference: https://ift.tt/3vr2oi5
