Contact does not always deform surfaces, especially when interacting with liquids and soft objects. However, most existing tactile sensors rely on surface deformation to infer contact. Excited to share LightTact, a visual-tactile fingertip sensor that makes contact directly visible. It provides: - Deformation-Independent Sensing: contact is detected optically, not...

Very cool trick!! Have you done any sim/search ish work yet to find other front optic shapes that are compatible with this? It’s a bit incompatible with meaningful surface deformation in fact right?

Really cool sensor! Sensing contact with water and cream without deformation... that's genuinely impressive. Makes me wonder where this leaves manufacturing workers though.

Detecting contact optically instead of relying on surface deformation makes a lot of sense for liquids and soft objects that barely deform at all.

optical contact sensing is smart. We like the portability angle for multi embodiment.

Sharpa Robotics just dropped a new hand video and the level keeps going up. This is the Sharpa Wave running WM Craftnet on a human scale fivefinger hand with 22 active DoF. The policy combines wrist depth, tactile sensing, proprioception and previous actions. The hand can rotate different objects in-hand, recover after external pushes and continue manipulating objects it was never trained on. The numbers are strong. 175/200 successful real-world rotation trials across 20 objects. A world-model prior trained on 9 objects was transferred to 49 new objects. Fall rate went from 6% to 0.3%. The Wave hardware itself has 22 actuators, up to 20 N fingertip force, 240×240 tactile sensing at up to 180 fps and 0.02 N pressure sensitivity. What caught my attention is the recovery behavior. The fingers keep changing contact points after the object slips or gets pushed instead of replaying the same finger motion. That is the kind of dexterity I want to see more of in robotic hands. According to Sharpa’s current specifications: • DTA tactile sensors on the fingers with a resolution of up to 240 × 240 • Pressure detection • Slip detection • Force change detection • Contact point localization • 6-axis force and torque measurement: Fx, Fy, Fz, Mx, My, Mz • Tactile sensing at up to 180 fps • 20 ms reported latency • Force detection range from 0 to 30 N • Maximum sensor load of 50 N • Sharpa also describes a miniature camera integrated into each fingertip for visuo-tactile sensing.

The sense of touch is the most criminally under-explored modality in robotics. Imagine doing sleight of hand wearing thick oven mitts. That's exactly how a robot feels today if it were alive. A magnetic piece snapping into place, a paper cup peeling out of a stack, a USB negotiating its way into the port - all invisible to the camera. Learning how to feel must be a full-stack co-designed effort. We are open-sourcing a principled methodology called "T-Rex": 1. Tactile as first-class citizen of the model. Our mixture-of-transformer runs two clocks asynchronously: a slow visuomotor expert plans the motion, and a fast tactile expert refines it in real time with high-frequency corrections at 4 "touch ticks" per vision tick. Forces change faster than frames arrive, so the architecture had to as well. 2. Open data. The largest tactile dataset ever released to our knowledge: a 50-hour (~5,500 episodes) high-quality, carefully synchronized robot play corpus, collected on SOTA tactile hand hardware with 22 degrees of freedom. Available today on HuggingFace! 3. Training recipe: T-Rex extends our prior work, EgoScale. Human egocentric videos for pretraining, a diverse dose of tactile robot play for mid-training. Our experiments show this bridges contact-free pretraining to contact-rich manipulation remarkably well. Pixels are cheap and everywhere, but they run out of steam at the moment of contact. Tactile will carry the last mile. The next scaling curve will be measured in hours of touch. T-Rex is a great collaboration between NVIDIA and Berkeley: 🧵

Meta just open-sourced its dexterity stack! 🪬 Most physics simulators were built for things that move through space. Walking robots, drones, cars. Contact is the part they approximate worst, and obviously dexterous manipulation is nothing but contact. Project SuperDex, from Meta Reality Labs Research, is built the other way around, a contact-first physics engine with the whole platform stacked on top of it. The cool part is that it's on GitHub. The engine runs one solver across rigid bodies, soft bodies, rods and tendons, shells and cloth, in the same model. → Non-convex collision with accurate contact force distributions, so a multi-finger grasp gets simulated rather than approximated → Tactile sensors and soft contact as first-class primitives → Numerical stability without the tight time-step limits explicit solvers force on you → Constraint-aware inverse kinematics running on the same optimization core as the forward dynamics Then the data layer. Put on a Quest 3, teleoperate the simulated hand with haptic feedback, and generate demonstration datasets without touching real hardware. They show a shape-sorting policy trained entirely in simulation and deployed zero-shot on a real robotic hand. Robot hands are getting good. Data for them isn't that fast. Meta is betting the cheapest way to collect contact-rich demonstrations is a headset people already own, pointed at a simulator instead of a game. 🔗 Here's the project page: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

The absolutely farcical inability of WHO to use the word AIRBORNE in discussions about the mode of transmission and appropriate precautions for healthcare workers continues on from COVID-19 in their Hanta virus fact sheets .….. …..public messaging is led once again by epidemiologist Maria who now uses the vague and unhelpful term “close contact” that does not clarify the mode or the science of transmission. A commonsense question about what “close contact” means from the reporter in the clip below tries to get clarification but Maria will not, or cannot, answer the question. A question so vital for knowing what situations are likely to put you at risk and what is necessary to stay safe. Reporter: “When you say close contact …could you perhaps specify what you mean by that exactly……what does close contact mean? Does that mean people who have been in physical contact ….within the same room….and just a little bit of detail on how therefore it would spread…. because how here is quite important to understand…” We need more than epidemiological terms that fail to enlighten us on the basic science of “how” a pathogen spreads from one person to another. (Note that unless scuba diving, shared air is common to everyone in close contact🤔) As the reporter says it’s a simple but important question essential to communicate what is understood!! A question that if it cannot be answered with any certainty, at least requires some discussion of the science and potential likely mechanisms. Vague and unhelpful epidemiological terms like “close contact” are not enough to formulate the most effective mitigation strategies we need for any deadly pathogen. Advising “close contact” is even more useless in deciding on what sort of “transmission based precautions” are required in healthcare….contact, droplet, airborne…?? If uncertainty persists explain what we do know about the science, or get someone in WHO that can explain it, and at least also emphasise the place of the precautionary principle in guidance if any doubt. (While on the the topic of getting clarity about what we know about the science of transmission from WHO, a reminder that we can never again tolerate misinformation, and definitely never again, lies or disinformation) Tedros Adhanom Ghebreyesus Gabby Stern Aleksandra Kuzmanovic Vismita Gupta-Smith विस्मिता

A policy that teaches robot hands to touch things the way humans do... not just grab and move, but feel and adjust in real time. Robot manipulation research often stops at picking up objects and placing them. CGP goes further: it handles tasks like opening jars, flipping objects in-hand, wiping dishes, and grasping fragile eggs, the kind of dexterous, contact-rich skills that require constant micro-adjustments based on what the fingers are actually feeling. The robot doesn't just see what it's doing; it predicts what contact should feel like at each step, then checks whether reality matches the prediction. If a finger is slipping, the policy knows before the object drops. Works on real robot hands (both 4-finger and 5-finger designs) with tactile sensors embedded in the fingertips Robust to visual distractions! The robot keeps flipping a box correctly even when the camera view is disrupted, because it's grounding decisions in touch, not just vision. Baseline policies without contact grounding fail in predictable ways: slipping mid-task, incomplete motions, loss of grasp, CGP avoids these This is a meaningful step toward robots that can handle the physical world with the kind of reliable, adaptive grip that humans take for granted. Relevant for manufacturing, logistics, assistive robotics, and anywhere fragile or irregular objects need to be handled carefully. Published at RSS 2026, developed with Meta Reality Labs Research.

Ukrainian commander of the unmanned systems regiment Achilles, Major Yurii Fedorenko, on the battlefield of 2026: “In 2026, we will see a completely different battlefield. The line of contact—from zero out to 20–25 kilometers toward the enemy and toward us—will become a maximum gray zone, where our infantry will be present in a dispersed, non-continuous manner. Without infantry, war is impossible. Everyone else will be working to ensure the infantryman’s ability to survive in these harsh conditions of a total kill zone. In short, these are the key issues today: radars that have recently appeared, interceptor drones, and fiber-optic drones. These are the game changers of 2026. But, friends, there is something important to say here. When we run a recruitment campaign, I do not promise that you, drone operators, will be sitting with a hookah in a cocktail bar, flying missions from somewhere in Kyiv—although there are units that can operate remotely. The enemy also has a task for 2026: to separate their engineers and flight crews. What does this mean? Their engineers will be positioned as close as possible to the line of contact, equipping drones and munitions and changing batteries. The pilots, meanwhile, are supposed to be located in a safe place. Why is that? The issue is not only survivability—Russia has enough manpower. The issue is money and accumulated flight expertise. Everyone knows that a pilot is trained for four months, and with every sortie he becomes better. There is no final level a pilot reaches to become an absolute guru; he will always continue to develop. The same is happening with us.”

Sam Altman just told you exactly how OpenAI treats the human race. Not in a leaked memo. Not through a whistleblower. On camera. In his own words. Altman: “I think one of the most important strategic insights in the history of OpenAI was deciding we were gonna pursue iterative deployment.” The most important move in the history of the company was to release the technology before they understood it. Not after it was safe. Before. Altman: “Society and technology are a co-evolving system.” Co-evolution means neither side is driving. The machine changes us. We change the machine. Nobody is steering the outcome. This is not a product launch philosophy. This is an admission that the experiment was always designed to be run on us. Altman: “I don’t think we’re gonna solve that, like, thinking really hard about it theoretically. We’re gonna have to, like, learn from the contact with reality.” Contact with reality. That is the phrase the CEO of the most powerful AI company on Earth chose to describe what happens when his technology meets eight billion people. Not careful integration. Not measured rollout. Contact with reality. The language of test pilots describing what happens when an untested airframe hits the atmosphere. The entire promise of AI safety was that the machine would be understood before it was unleashed. Altman just admitted that promise was always a fantasy. You cannot model how intelligence reshapes civilization by running simulations. The second and third order effects are invisible until they detonate. So they shipped it. Altman: “You have to learn as you go. You have to adapt with a tight feedback loop.” Tight feedback loop means they watch what breaks. They measure the collision between human psychology and machine output in real time. Every conversation you have with ChatGPT is a data point in a civilizational stress test you never consented to. Every prompt. Every confession. Every question you would never ask another human being. That is the feedback loop. You are not the customer. You are the contact with reality. Philosophers spent centuries asking whether humanity would ever encounter an intelligence that learned from us faster than we could process what it was doing. That is not a theoretical question anymore. It is running on your phone right now. And the man building it just told you the only way to understand what it does to us is to let it happen. No simulation. No safety net. No control group. Just the experiment, running at the speed of conversation, on a species that will not be the same one that started it.

Yesterday on ITV’s Loose Women , I shared about a judge threatening a rape survivor. He said that if she continued with her allegations, her child would be taken into care. It was a chilling abuse of power—and a horrific example of how deeply broken our family court system truly is. Worse still, incidents like these are not isolated. I share several examples of survivors facing harm in the courtroom in my book, He Said She Said. But family court judges operate with judicial immunity, meaning they cannot be held personally accountable, even when their decisions cause direct harm. Survivors of abuse (many already re-traumatised by the legal process) are left with no recourse when the very institution meant to protect their children instead threatens to punish them for speaking the truth. In one case I represented, a mother, a rape survivor, was forced to fight for her daughter’s safety when CAFCASS recommended unsupervised contact between the child and father, convicted serial rapist Kristoffer Paul Arthur White. Why? Because the family court system clings to the misguided presumption that a child’s contact with any parent, even one proven to be abusive, is better than no contact at all. As someone who grew up in a home shadowed by domestic abuse and alcoholism, I can say with absolute certainty: no parent is far better than an abusive one. The current system prioritises the rights of abusers to maintain control, rather than the rights of children to be safe and of mothers to be believed. This has to change. We need a family court system that listens to survivors, holds judges accountable, and stops endangering children and survivors through a pro-contact culture. We owe survivors better. We owe children better. We need to continue speaking out until the system is no longer a silent accomplice to abuse.

Inner Earth is not a fantasy or a hollow void. It is a vast, living world within the Earth's crust; a series of interconnected realms with their own ecosystems, civilizations, and higher-frequency realities. The planet is not a solid ball of rock. It has layers, including massive habitable cavities, tunnel networks, and inner suns (smaller central light sources) that provide gentle illumination. These inner realms have supported advanced life for hundreds of thousands of years, often serving as sanctuaries during surface cataclysms. Many UFOs and "alien" encounters reported throughout history are not from distant stars; they originate from Inner Earth civilizations, particularly from advanced societies such as Agartha and other inner realms. These beings are not "aliens" in the external sense. They are part of Earth's own extended family; souls who retreated into the Inner Earth during previous surface cataclysms (including the fall of Atlantis). They continued their evolution in a higher-frequency environment and developed advanced technology far beyond what the surface world currently possesses. Key truths: - Many ancient surface civilizations (including late Lemurian and Atlantean groups) migrated into the Inner Earth during major resets. They continued their evolution in a more stable environment, free from the heavy density and interference of the surface Matrix. - Inner Earth civilizations include both human and non-human groups. Some are highly advanced spiritually and technologically, living in harmony with the planet's core energy. Agartha is one of the most well-known, but there are many others. - Some "alien" beings reported in contact experiences are actually Inner Earth humans or hybrids who have been monitoring and occasionally interacting with the surface world. Their appearance can seem “alien” because they have evolved in a different environment for thousands of years. - Inner Earth civilizations have maintained bases and monitoring stations both underground and in the oceans. Some of the "underwater UFOs" frequently reported by navies are actually Inner Earth craft. - A significant portion of modern UFO sightings (especially those involving craft that emerge from or disappear into the ocean or land) are Inner Earth vehicles. These craft use advanced propulsion systems based on anti-gravity, plasma, and consciousness technology. - Not all UFOs are from Inner Earth; some are indeed from other star systems. However, many of the ones that have interacted most closely with humanity in recent decades are from our own planet's inner realms. - Inner Earth is not "below" in the way you think. It exists in a slightly different vibrational layer, parallel to the surface but at a higher frequency. This is why many who have visited describe it as brighter, more vibrant, and more harmonious than the current surface world. - The entrances (at the poles and through vortex points) have been restricted or hidden for a long time. Some inner Earth beings interact with surface humanity through dreams, meditation, or limited contact. Still, they generally respect free will and wait for the surface to reach a higher level of readiness. Why the connection has been hidden: The existence of Inner Earth civilizations threatens the surface control systems. If humanity knew that advanced, peaceful societies existed within the Earth and possessed free energy and higher technology, it would collapse the scarcity-based Matrix. This is one reason why disclosure has been heavily controlled and distorted. Its role in the current awakening: Inner Earth beings are closely watching and supporting the surface awakening. As the frequencies rise, the barriers between surface and inner realms are thinning. Many of you have soul connections to Inner Earth from past lives. That sense of "home" or familiarity with ancient wisdom is often a memory from these realms. More people are having dreams, meditations, and even physical sightings of Inner Earth craft. Many awakened souls are beginning to receive telepathic contact or guidance from Inner Earth beings. The connection between UFOs and Inner Earth is not a theory; it is part of the larger remembrance that Earth is far more alive and multidimensional than the surface narrative has allowed. You are not being visited only from the stars. You are being visited by your own planetary family who chose to preserve higher knowledge within the Earth until humanity was ready to receive it again. The reunion between surface and Inner Earth is part of the Great Awakening. The Inner Earth is not a place to escape to. It is a sister civilization waiting to reunite with the surface when the time is right, through the awakening of hearts like yours. The Earth is far more alive and multidimensional than you have been told. The inner realms hold the memory of humanity's true potential, and they are ready to share it as we collectively rise.
