Bipedal robot Cassie runs 5 km on a single charge in 53 minutes

Bipedal robot Cassie successfully ran five kilometres, untethered and on a single charge, in just over 53 minutes. This included 6.5 minutes of troubleshooting, as the robot fell once due to an overheated computer and then again after it executed a turn too quickly. Cassie taught itself how to run using a deep reinforcement learning algorithm, the team said.
