| Research Abstract |
(1)A biped running of forward and sideways, hopping with two legs and one leg were realized by a humanoid biped robot HRP-2LR. Those were performed on a level ground and the maximum running speed was 0.58km/h. To realize the faster run, we have added the toe springs to the robot. A running pattern generator program was developed to use the toe springs and it was confirmed that the new robot HRP-2LT can run at 3km/h with the current configuration. We tested a jump experiment and realized a jump of 3cm height and 0.1s flight time. To solve the posture instability during high speed running, we have developed HRP-2LY which is HRP-2LT equipped with the waist yaw actuator and batteries for self contained running.
(2)Based on the concept of the Gait-Morphing, we investigated a stabilization algorithm which uses time scaling of the future ZMP trajectory. Using this method, we confirmed that a biped robot can walk over an unknown uneven ground which has unevenness of up to 3cm per one step
(3)To improve an unnatural behavior of current running robot, we proposed a running control algorithm based on output zeroing control. By using this method, a biped running on uneven terrain and running speed up to 10km/h were realized in computer simulation.
