ABSTRACT:
A gait generation system of a legged mobile robot, in particular a biped robot that has the dynamic model expressing the relationship between the motion of the body and leg and the floor reaction force, and provisionally determines the current time gait parameters including at least parameters that determine leg trajectory and the like in response to a demand, supposes the parameters of a periodic gait, corrects the current time gait parameters such that the body trajectory determined from the dynamic model and the parameters of the current time gait, etc., converges to a body trajectory determined from the parameters of the periodic gait, and determines instantaneous values of the current time gait based on the corrected current time gait parameter. With this, the system can generates a gait of any stride, turning angle and walking period, including the floor reaction force acting on the legged mobile robot, that satisfies the dynamic equilibrium condition. Further, the system can generates a gait in such a manner that the displacement and velocity of each robot part are continues at the boundary of the generated gait and that succeeding thereto, can generate a gait that is high in the margin of stability, can predict future behavior of the robot and generate a gait such that no disadvantages such as posture divergence occurs.
