Salto is a jumping robot that is all heart (and legs). A project originally launched in 2017 this tiny robot thrusts itself up and down and back and forth like a crazed grasshopper, jumping with absolute precision and loads of speed.

Created by the UC Berkeley’s Biomimetic Millisystems Lab, this little robot uses rotor-based thrusters and bouncy legs to do its tricks.
