Robots that feel pain react faster than humans
NEWYou can now listen to Fox News articles!
Touch something hot, and your hand snaps back before you even think. That split second matters.
Sensory nerves in your skin send a rapid signal to your spinal cord, which triggers your muscles right away. Your brain catches up later. Most robots cannot do this. When a humanoid robot touches something harmful, sensor data usually travels to a central processor, waits for analysis and then sends instructions back to the motors. Even tiny delays can lead to broken parts or dangerous interactions.
As robots move into homes, hospitals and workplaces, that lag becomes a real problem.
A robotic skin designed to mimic the human nervous system
Scientists at the Chinese Academy of Sciences and collaborating universities are tackling this challenge with a neuromorphic robotic e-skin, also known as NRE-skin. Instead of acting like a simple pressure pad, this skin works more like a human nervous system. Traditional robot skins can tell when they are touched. They cannot tell whether that touch is harmful. The new e-skin can do both. That difference changes everything.

CES 2026 SHOWSTOPPERS: 10 GADGETS YOU HAVE TO SEE

How the neuromorphic e-skin works
The e-skin is built in four layers that mirror how human skin and nerves function. The top layer acts as a protective outer covering, similar to the epidermis. Beneath it sit sensors and circuits that behave like sensory nerves. Even when nothing touches the robot, the skin sends a small electrical pulse to the robot every 75 to 150 seconds. This signal acts like a status check that says everything is fine. When the skin is damaged, that pulse stops. The robot immediately knows where it was injured and alerts its owner. Touch creates another signal. Normal contact sends neural-like spikes to the robot’s central processor for interpretation. However, extreme pressure triggers something different.
How robots detect pain and trigger instant reflexes
If force exceeds a preset threshold, the skin generates a high-voltage spike that goes straight to the motors. This bypasses the central processor entirely. The result is a reflex. The robot can pull its arm away instantly, much like a human does after touching a hot surface. The pain signal only appears when the contact is truly dangerous, which helps prevent overreaction. This local reflex system reduces damage, improves safety and makes interactions feel more natural.

Self-repairing robotic skin makes fixes fast
The design includes another clever feature. The e-skin is made from magnetic patches that fit together like building blocks. If part of the skin gets damaged, an owner can remove the affected patch and snap in a new one within seconds. There is no need to replace the entire surface. That modular approach saves time, lowers costs and keeps robots in service longer.
Why pain-sensing skin matters for real-world robots
Future service robots will need to work close to people. They will assist patients, help older adults and operate safely in crowded spaces. A sense of touch that includes pain and injury detection makes robots more aware and more trustworthy. It also reduces the risk of accidents caused by delayed reactions or sensor overload. The research team says their neural-inspired design improves robotic touch, safety and intuitive human-robot interaction. It is a key step toward robots that behave less like machines and more like responsive partners.
What this technology means for the future of robots
The next challenge is sensitivity. The researchers want the skin to recognize multiple touches at the same time without confusion. If successful, robots could handle complex physical tasks while staying alert to danger across their entire surface. That brings humanoid robots one step closer to acting on instinct.

Kurt’s key takeaways
Robots that can feel pain may sound unsettling at first. In reality, it is about protection, speed and safety. By copying how the human nervous system works, scientists are giving robots faster reflexes and better judgment in the physical world. As robots become part of daily life, those instincts could make all the difference.
Would you feel more comfortable around a robot if it could sense pain and react instantly, or does that idea raise new concerns for you? Let us know by writing to us at Cyberguy.com.

When Oregon resident Isabelle Reksopuro heard Google was gobbling up public land to fuel its data centers in her home state, she didn’t initially know what to believe. “There’s a lot of misinformation about data centers,” she said. “Google has denied taking that land.”
Technically, she explains, The Dalles, a city near the Washington state border, sought to reclaim that land, “and Google is just a big, unnamed power user.” The city had in fact asked for ownership of a 150-acre portion of Mount Hood National Forest, claiming it needs access to Mount Hood’s watershed to meet municipal needs as its population — 16,010 as of the 2020 census — grows. But critics, including environmentalists, say the city is trying to secure more water for Google, which has a sprawling data center campus in The Dalles that already consumes about one-third of the city’s water supply.
This controversy made Reksopuro curious about the backlash to data centers being built in other communities. So Reksopuro, a student at the University of Washington who studies the connections between tech and public policy, decided to map it out. Using information collected by Epoch AI and data scraped from legislation on data centers, she built an interactive map tracking AI policy around the world. She designed it to be simple enough for anyone to use. “I wanted it to be something that my younger sisters could play through and explore to understand what are the data centers in the area and what’s actually being done about it,” Reksopuro said. She hoped to shift their opinions that way, “instead of like, through TikTok.”
Four times a day, the map searches for new sources and checks them against the existing database Reksopuro built out. “Once it does that, it will write a new summary, add it to the news feed, and populate it on the sidebar,” she said. “I wanted it to be self-updating, since I’m also a student.”
Reksopuro isn’t against data centers, but she thinks tech giants benefit from a lack of transparency around data center policies. “Right now, it’s this really opaque thing — and all of a sudden, there’s a facility,” she said. “I think that if people knew about data centers beforehand, it would give them leverage. They would be able to negotiate: ask for job training programs, tax revenue, environmental monitoring, things to improve their community.”

Microsoft Edge is adding a new feature that will allow its Copilot AI chatbot to gather information from all of your open tabs. When you start a conversation with Copilot, you can ask the chatbot questions about what’s in your tabs, compare the products you’re looking at, summarize your open articles, and more.
In its announcement, Microsoft says you can “select which experiences you want or leave off the ones you don’t.” The company is retiring Copilot Mode as well, which could similarly draw information from your tabs but offered some agentic features, like the ability to book a reservation on your behalf. Microsoft has since folded these agentic capabilities into its “Browse with Copilot” tool.
Several other AI features are coming to Edge, including an AI-powered “Study and Learn” mode that can turn the article you’re looking at into a study session or interactive quiz. There’s a new tool that turns your tabs into AI-powered podcasts as well, similar to what you’d find on NotebookLM, and an AI writing assistant that will pop up when you start entering text on a webpage.
You can also give Copilot permission to access your browsing history to provide more “relevant, high-quality answers,” according to Microsoft. Copilot in Edge on desktop and mobile will come with “long-term memory” as well, which can tailor its responses based on your previous conversations. And, when you open up a new tab, you’ll see a redesigned page that combines chat, search, and web navigation, along with the Journeys feature, which uses AI to organize your browsing history into categories that you can revisit.
Meanwhile, an update to Edge’s mobile app will allow you to share your screen with Copilot and talk through the questions about what you’re seeing. Microsoft says you’ll see “clear visual cues” when Copilot is active, “so you know when it’s taking an action, helping, listening, or viewing.”
