摘要
提出了仿人跑步机器人在跑步时关节力矩控制和前向速度控制的方案。对于机器人关节力矩的控制,通过推导机器人的三维动力学方程以及机器人质心和双脚的轨迹,采用阻抗控制的方法实现;对于机器人前向跑步速度的控制,通过在起跳阶段起始时刻调节"虚拟腿"与铅垂线的夹角实现,这种控制方法的优点是简单易行。最后采用虚拟样机软件ADAMS建立了仿人跑步机器人的三维模型,通过仿真证明了这种方法的有效性。
The control scheme of each joint driving torque and forward speed for humanoid running robot was proposed when the robot was running. The control algorithm for each joint torque of the robot was realized by using the impendence control according to deducing the dynamical equation in three dimensions of the robot and the trajectories of the center of mass (COM) and two feet of the robot. Next, the forward speed of the robot was controlled by adjusting the angle between the "Virtual Leg" and the vertical line at the beginning of the stance phase, which has an advantage of simplicity and feasibility. Finally, the virtual model of the robot was built by the software ADAMS and the validity of the method was verified by the simulation for the virtual model of the robot.
