本文章描述四自由度机械臂的matlab仿真方法，使用到robot工具箱-This article describes the four degrees of freedom manipulator matlab simulation method using the robot kit

对微机械臂受力分析得到运动学方程，求解后得出微机械臂的关节力矩和宏机械臂末端作用力的关系。在已知柔性臂末端的弹性变形和振动情况的基础上，用PD控制原理使微机械臂关节产生所需力矩(The kinematics equation of the mechanical arm was obtained. The relationship between the joint torque of the micromanipulator and the end force of the macro mani
