| Research Abstract |
This study study aims at realizing 3D dynamic biped locomotion in a robot. In human dynamic walking, a stable limit-cycle is formed as a whole by repeating the unstable motions as an inverted pendulum. In this study, a hierarchical control strategy in which the information from many sensors was utilized was proposed, and its effectiveness was confirmed by experiments under the circumstamces with stairs using a biped robot.
(1)The optimal torque distribution under the circumstance with stairs was decided by using the dynamic equations of motion during the double support phase. In this calculation, the summation of the joint torques is minimized within the limits in which the slippage of the sole and like do not happen. This torque distribution is stored in the control computer, and is used in the walking experiments.
(2)The optimal variation of the angular momentum of the robot system under the circumstance with stairs was also derived from the dynamic equations of motion.
(3)The walking experiments on the continuous ascending stairs were conducted by using the above torque distribution and the optimal variation of the angular momentum.
