摘要

为提高双足机器人的轨迹规划效率,建立了完整的规划机制。采用D-H法建立了机器人腿的运动学模型。在两足机器人完整运动学模型的基础上,完成了机器人腿的轨迹规划。通过增加多个几何约束,提高了机器人的稳定性。根据规划的轨迹方程,通过求解方程组得到各关节的转角。利用3DS MAX软件建立了双足机器人的三维模型。建立了伺服驱动器与虚拟运动控制软件之间的伺服接口,并利用Visual Studio软件进行编程。实验结果表明,该机构可大大提高工作效率,并具有良好的控制性能。

Algorithm and implementation of joint trajectory planning for virtual robot's legs
A complete planning mechanism was established to improve efficiency of trajectory planning of biped robot. The kinematic model of robot's legs was built by D-H method. Trajectory planning for robot's legs was finished based on complete kinematic model of the biped robot. The stability of the robot was improved by adding multiple geometrical constraints. Rotation angles of each joint were obtained by solving equation sets based on the planned trajectory equations. The 3D model of biped robot was built by the software of 3DS MAX. The servo interface between servo drivers and the virtual motion control software was created which was programmed by software of Visual Studio. Experiment results indicate that the mechanism can promote working efficiency greatly as well as having good control performance.
