Abstract

Walking according to changes in the environment is called adaptive walking. We define lower level adaptive walking as a walk consisting only of trajectory control and walk-pattern generation. The purpose of this study was to realize lower level adapting walking in the sagittal plane by a biped locomotion robot in indoor space. In this paper, we propose a simplified procedure of walk-pattern generation, which is that walk patterns for various environments are generated by adjusting and combining the basic walk patterns which have previously been given for typical environments. Based on this idea, walking experiments were carried out for various environments. As a result, dynamic walking in a flat plane (about 1.5 s/step with a 0.3 m step width), changes of the step width in walking, and walking in various environments combined from a flat plane, an obstacle (such as a pipe) and a stair (up and down) were realized.
