Salto-1P is a small, one-legged jumping robot inspired by the lesser bushbaby, a small nocturnal primate (scientific name Galago senegalensis). Salto-1P's powerful, springy leg enables it to jump high and fast. Using a reaction wheel tail on its side and propeller thrusters on top, it can balance and hop around.

Salto-1P can measure the force on its leg by measuring the deflection of its spring.
Salto, a small monopedal jumping robot, was created by Justin Yim while he was a PhD student at UC Berkeley in Ron Fearing's Biomimetic Millisystems Lab. Salto-1P uses a small motor and a system of linkages and gears to jump. Because it spends so little time in contact with the ground, the robot needs to do most of its control in the air. To do that, it uses a rotating inertial tail and two little thrusters to stabilize and reorient itself in between jumps. The robot can bounce up and over obstacles, and it can also land on a target spot. Yim is now at the University of Illinois Urbana-Champaign in the Mechanical Science and Engineering department.
