RAI Institute Roadrunner Other Robot

Roadrunner is a bipedal wheeled robot from RAI Institute (formerly Boston Dynamics AI Institute) that seamlessly switches between rolling on wheels and stepping/walking. Weighing only 15 kg, it can climb stairs, balance on a single wheel, and navigate narrow passages using a unified control policy trained entirely in simulation with zero-shot real-world transfer.
