Meet the Salto-1P: a small monopedal jumping robot capable of hopping continuously. Researchers have come up with a new control algorithm that enables the robot to play one-leg hopscotch. With precise foot placement, Salto-1P can jump on surfaces like furniture.
Salto-1P bounces like a pogo stick. The DFPH controller sets the velocity using leg angle and retraction and quickly retarget. More info is available here.
