Dynamic Locomotion and Mechanism of Biped Walking Robot

Abstract

The walking biped robot (WABIAN-2LL) can imitate human motions such as knee-stretching locomotions and deep bending motions because it is designed with large movable ranges as a human. It has two seven degrees of freedom, (DOF) legs and a two DOF waist. Each leg consists of a three DOF ankle, a one DOF knee and a three DOF hip to deal with human walking motion. Its height is about 1.2[m], and its weight is 40[kg]. Also, how to make a knee-stretched walk pattern is proposed. During the walking, moments generated by the motion of the legs should be cancelled. So, a compensatory motion control algorithm, is used which is based on the waist motion. Through dynamic walking experiments, the effectiveness of the biped robot is confirmed
