Carnegie Mellon University researchers used an artificial intelligence (AI) to train a robot dog to perform cleaning tasks for less than a tenth of the cost of Boston Dynamics' robot canines. The researchers taught the AI to coordinate the robot's movements with an arm affixed to its back while an operator guided its activity.
They applied reinforcement learning to train the AI via computer models and in a physical machine. The researchers trained the AI to direct the robot's legs separately from the arm, before training it on leg/arm coordination. The team also had a teacher AI train a student AI to mimic their bodily motions.
