摘要
以UR5机器人为研究对象,为提高作业效率并保证其运动的平稳性,对其进行运动学分析与轨迹规划研究。采用D-H方法对机械臂的正、逆运动学进行了分析。以关节最大速度为约束,结合五次多项式得到了机械臂各关节的轨迹。通过建立机器人的Simulink控制模型,以关节角速度为输入,得到关节的角加速度曲线。通过对比轨迹规划与模型仿真的结果,验证了运动学方程的准确性。
Taking the UR5 robot as the research object, in order to improve the working efficiency and ensure the stability of its movement, the kinematics analysis and trajectory planning were studied.Using the D-H method to analyze the forward and inverse kinematics of the manipulator. Taking the maximum joint speed as the constraint and combining the fifth degree polynomial, obtained the joints of the manipulator trajectory. By establishing the Simulink control model of the robot and taking the joint angular velocity as input, the angular acceleration curve of the joint was obtained. By comparing the results of trajectory planning and model simulation, the accuracy of the kinematics equation was verified.
