A 3D-printed bipedal robot inspired by the design of a commercial-scale robot aims to provide an open-source platform for studying and applying reinforcement learning. David Ho, a master’s student in robotics at University of Michigan, developed the one-foot-tall robot, named Legolas.

The design of Legolas is inspired by Agility Robotics’ Cassie robot. This includes inverted legs, like the namesake Cassowary bird.
