Scientists gave robots the ability to sweat

  Scientists gave robots the ability to sweat Now, researchers from Cornell University have developed a robotic hand that is equipped with fingers for gripping objects. That on its own isn’t particularly impressive, but these soft robo-fingers do something that is entirely new: they sweat. Like human muscles, robotic components generate heat as they are used, especially for repetitive motion. In the case of a robotic hand, the action of gripping can generate heat that might otherwise impair the robot’s ability to grip things properly.

Facebook might have a solution. It recently developed a distributed reinforcement learning algorithm that not only reaches its destination 99.9 percent of the time without using maps , but The trick was to implement a new training method that scaled well and stayed in sync no matter what the workload.

WhatsApp has been the holdout of Facebook ' s three big standalone apps when it comes to dark mode. Messenger was the first to enable it back in early 2019, with Instagram following suit in October. Although the Dark Theme is currently limited to beta versions of the Android app, it probably won't be

  Facebook's new robot AI can get around efficiently without using a map

It's already possible for robots to navigate without maps, but having them navigate well is another matter. You don't want them to waste time backtracking, let alone fall down if they bump into an unexpected obstacle. Facebook might have a solution.

It recently developed a distributed reinforcement learning algorithm that not only reaches its destination 99.9 percent of the time without using maps, but can do so with just a three percent deviation from the ideal path. DD-PPO (Decentrialized Distributed Proximal Policy Optimization), as it's called, doesn't need more than a standard RGB camera with depth data, GPS and a compass.

Gallery: These big businesses are already replacing humans with robots (lovemoney) 

a group of people sitting at a table: The rise of robots is no longer mere science-fiction, with robotics and artificial intelligence infiltrating nearly every area of our lives. From self-serve checkouts in supermarkets to screening legal documents, robots are now working more efficiently and economically than we do. So it's no surprise that a recent report predicts that robots will take over 800 million jobs by 2030, which would affect one-fifth of the global workforce. But what do robots in the workplace actually look like? /

The trick was to implement a new training method that scaled well and stayed in sync no matter what the workload. Previous projects tend to struggle without massive computational power. Facebook taught a virtual agent to handle point-to-point navigation for the equivalent of 80 years of human experience -- that's about 2.5 billion steps. The result is an algorithm that, in indoor environments, is smart enough to choose the right fork in the path and quickly recognize errors when it does head in the wrong direction. It's learning to understand the "structural regularities" of buildings, Facebook speculated.

The technology is still very young. It has yet to handle outdoors or complex situations, and it doesn't handle long-distance navigation well if it has to lose sensors. Facebook is sharing its work in hopes of further advances, though. If that happens, it could not only help robots move gracefully from room to room, but help with augmented reality glasses and other systems that help you navigate unfamiliar spaces.
