AI teaches 4-legged robots how to recover when they fall

“Teaching robots to walk is one thing, but what about helping them to learn how to recover from a stumble?” writes Kyle Wiggers for Over the course of 50 tests where the robot started from a lying position, the self-righting policy managed to recover within 5 seconds.Additionally, they proved to be remarkably robust, because they were able to handle unpredictable scenarios such as when the robot’s legs become stuck below its base.The researchers concede that the system was only trained and tested on flat ground, meaning it’d likely fail in case of large inclines or rough terrain.
