Abstract :
Adaptive gait for limb mechanism robot ASTERISK´s dynamic rotational walking motion is designed. The adaptive gait is a motion where the robot can adapt itself to environment by utilizing virtual plane without any case-by-case command for each situations from user. With internal sensing and proposed method, the robot knows how to response to its environment. As all the terrains in actual world is not ground leveled, the authors also optimized robot postures for each virtualized plane inclined-angle by using Genetic Algorithms. The adaptive gait is confirmed in the dynamic simulator, Open Dynamic Engine, before testing with actual robot. The robot could walk on the terrain with approximately 6 degree in both upward and downward directions without falling down.
