Watch Cassie the bipedal robot run a 5K:
Cassie, a bipedal robot that's all legs, has successfully run five kilometers on a single charge, all without having a tether. The machine serves as the basis for Agility Robotics' delivery robot Digit, as TechCrunch notes, though you may also remember it for "blindly" navigating a set of stairs. Oregon State University engineers were able to train Cassie in a simulator to enable it to go up and down a flight of stairs without the use of cameras or LIDAR. Now, engineers from the same team were able to train Cassie to run using a deep reinforcement learning algorithm.
According to the team, Cassie teaching itself using the technique gave it the capability to stay upright without a tether by shifting its balance while running. The robot had to learn to make infinite subtle adjustments to be able to accomplish the feat.
