【Abstract】 Taking the 6-DOF welding robot as the object,it uses the standard D-H parameter method to establish the coordinate system and kinematics equation,builds the robot motion model in MATLAB/Robotics Toolbox,and simulates the positive motion and trajectory planning,obtains a continuous and stable curve of the end trajectory and joint angular displacement,angular velocity,and angular acceleration. Combining with the specific workpiece,it carries out the trajectory simulation and actual experiment. The trajectory curve obtained with the actual welding point fitting has good consistency with the simulated trajectory curve. The simulation result has high precision and good stability,and provides great development for offline programming systems for subsequent robots.更多还原
