摘要
针对袋鼠生物体结构及其腾空阶段的运动特点,提出了仿袋鼠跳跃机器人腾空阶段的运动特性分析方法。采用D-H法建立了仿袋鼠跳跃机器人腾空阶段的运动学分析模型,基于拉格朗日方法推导了其腾空阶段的动力学方程,最后利用MATLAB结合实例对此模型进行了仿真分析。结果表明,仿袋鼠跳跃机器人的髋关节和膝关节对于整个机器人的空中姿态调节有着决定性的作用。研究结果为仿袋鼠跳跃机器人的试验研究和驱动器的选择提供了理论参考。
Based on the body configuration and kinematics characteristics of kangaroo in its flight phase, a new method to analyse the torque characteristics was presented. A model to simulate the kangaroo robot in the flight phase was also founded using D-- H method. The equations of the model were derived using Lagrange method and the model was simulated by Matlab at last. The results show that, the hip and knee joints play the most important role in tuning the configuration of kangaroo hopping robot in flight phase, which is the basis for the experimental research and choosing driving actuators.
