Researchers Create the First AI-Controlled Robotic Limb That Can Learn To Walk Without Being Programmed (sciencealert.com)

schwit1 shares a report from ScienceAlert: Researchers at the University of Southern Carolina (USC) claim to have created the first AI-controlled robotic limb that can learn how to walk without being explicitly programmed to do so. The algorithm they used is inspired by real-life biology. Just like animals that can walk soon after birth, this robot can figure out how to use its animal-like tendons after only five minutes of unstructured play.

Today, most robots take months or years before they are ready to interact with the rest of the world. But with this new algorithm, the team has figured out how to make robots that can learn by simply doing. This is known in robotics as "motor babbling" because it closely mimics how babies learn to speak through trial and error. "During the babbling phase, the system will send random commands to motors and sense the joint angles," co-author Ali Marjaninejad an engineer at USC, told PC Mag. "Then, it will train the three-layer neural network to guess what commands will produce a given movement. We then start performing the task and reinforce good behavior."

      What's really *cool* with an arm trained by machine learning it doesn't have to get it exactly right. Close enough is plenty good for many tasks that do not require finesse, like crushing or walking in a general direction, etc

      Most of the "breakthroughs" in AI are from about 20 years ago. Turns out much of what failed then failed because their neural nets were too small. Also, sometimes things work when rediscovered because the person is implementing the idea independently without the baggage of wrong ideas that seemed correct and lead people down the wrong path.

      Everything but incremental improvements "didn't really work" until one day someone figured out how to make it work. Hopefully they give appropriate credit.
