Toward Realization of a Brainless Staggering Robot That Doesn’t Fall Down When Kicked

Abstract

Legged walking animals can stabilize their posture without falling down using only a few legs. In this study, we aim to reproduce and understand the staggering motion, a strategy to recover posture by moving the legs as quickly as possible in response to a change in posture. In order to reproduce the staggering motion seen in animals and humans, this paper reports on a robot that performs staggering motion by using a brainless approach in which the entire robot body is controlled by pure mechanisms such as valves and switches, without using any kind of computation such as animal brains.
