Swizzle Movement for Biped Walking Robot Having Passive Wheels

Abstract

Biped walking is easily adapted to rough terrain such as stairs and stony paths, but speed and energy efficiency on flat surfaces is less effective than wheeled locomotion. We propose new control for swizzling by biped walking robots using inline skates. Swizzling uses friction force generated by regular passive wheel movement. Our proposal is based on the reaction force on the foot, and new reference position is changed based on reaction force not to be large internal force. Through hardware experiments, the effectiveness of the proposed method was confirmed.
