Trung Phan(@TrungTPhan):An engineer that built this 400m-running humanoid robot explained the wild form: ▫️initially designed it with human arm swing ▫️but swinging arms too much put heavy load on shoulder joints, led to overheating (and robot couldn’t finish 400m) ▫️robot invented the new running style on its own (hands held up near face to reduce shoulder load while legs could keep trucking) ▫️per Global Times, “in a simulated learning environment…the team gave the robot continuous rewards, and through repeated iteration on the data it gradually settled into a posture that suited it better.” *** Full read here (fascinating): https://t.co/hfd7PCRIqM
