基于SLIP模型的液压驱动单腿机器人竖直跳跃控制
Vertical hopping control of hydraulically actuated single-legged robot based on SLIP
摘要
Abstract
For the vertical dynamic hopping control of hydraulically actuated legged robot, a control strategy based on the vertical hopping dynamics of SLIP (spring loaded inverted pendulum) was presented. The vertical hopping dynamics of SLIP was analyzed and the motion trajectory of its CoM (center of mass) was obtained by solving the differential equation of its dynamics. The motion trajectory of articulated single-legged robot's hip was mapped to that of SLIP's CoM. Then the joint motion trajectory, which drove the robot's joint motion, was obtained by inverse kinematics of robot. Furthermore, by establishing the vertical hopping dynamics of articulated single-legged robot and hydraulic actuator dynamics, the simulation of vertical hopping was done in the software of MATLAB/Simulink. And meanwhile the vertical hopping experiment was done on robot prototype. The results show that the hydraulically actuated single-legged robot is able to hop continuously and stably with a control strategy based on the vertical hopping dynamics of SLIP, which provides reference for the control of the dynamic gait walking of legged robot.关键词
