ETH Zurich's ANYmal quadruped solves a giant Rubik's Cube with its front feet

Researchers at ETH Zurich's Robotic Systems Lab got an ANYmal-D to solve an oversized 4.6 kg Rubik's Cube using its front legs while balancing on its hind legs. The robot scans the cube with its camera, plans about 30 moves with a solver and uses a reinforcement-learned balance policy; each of three runs took eight to nine minutes, showing legged robots can manipulate objects without arms.
