Navigation strategy for a quadruped robot on soft flat ground

摘要

Tasks important for a mobile robot are the environmental recognition and the obstacle avoidance in the real world. The legged robot can be adapted for rough terrains. It is because the legged robot has a high degree of freedom in order to avoid an obstacle to three dimensions. In this paper, we propose a locomotion strategy on the terrain with stiffness which is different in each. The propriety of a continuation walk is determined by the force sensor mounted to the bottom of each leg of a quadruped robot. The effectiveness of the proposal approach is verified from the result of the experiment which uses the prevalent quadruped robot called TITAN-VIII.
