One-leg jumping with virtual spring principle

Abstract

One-leg jumping of a biped robot with virtual spring principle is proposed and experimentally implemented. A biped robot is modeled and controlled as a simple mass-spring system, and its trajectories for jumping and landing are consequently planned as the mass-spring system. The jumping condition and necessary constraint conditions are deduced. Finally one-leg jumping of 130[ms] flight time is achieved with our developed biped robot MARI-3.
