Abstract
In this paper, dynamic biped locomotion is considered with the goal of achieving fast and dexterous leg motion. We propose a new movement principle for legged robots, which produces propulsive force using frictional asymmetry. The dynamic locomotion consists of sliding motion based on the kinematic constraint and jumping motion which enables to keep the maximum horizontal velocity. The dynamics of the 2-DOF biped robot is analyzed to obtain motion characteristics for developing a motion strategy. Experimental results are also shown in which a 2-DOF biped robot takes fast short steps repetitively with compensation of the landing time by high-speed vision.
