摘要
针对三自由度转载机械臂各关节的运动特点建立连杆坐标系。采用D-H方法建立了以关节为变量的机械臂运动学模型。采用齐次变换矩阵推导出系统的正运动学方程;采用反变换法求取运动学的逆解。通过运用Matlab软件中Robotics Toolbox进行仿真实验,验证了三自由度机械臂运动学模型及逆解计算的正确性。
A coordinate system of connecting rod is established based on the joint characteristics the three-degree-of-freedom revolving robot arm.D-H method is used to build the kinematics model of the manipulator with the joints as variables.We deduce the forward kinematics equation with homogeneous transformation matrix and obtain inverse solution of kinematics with inverse transform method.Simulation based on Robotics Toolbox in Matlab is carried to verify the kinematics model of the three-degree-of-freedom manipulator and the inverse solution calculation.
