Based on Matlab Robotics Toolbox, only simple simulation and verification can be carried out. It is urgent to design comprehensive innovation experiments to cultivate learning ability and engineering practice ability of students. By integrating computer vision and robot theoretical knowledge, a comprehensive simulation experiment of image contour rendering including image segmentation and edge detection, forward and inverse kinematics, and path planning is proposed. The purpose of the experiment is to cultivate students to solve problems in the field of complex robots, and guide students to form a unique way of thinking in the field of robotics. It has important theoretical significance and practical value for the cultivation of students majoring in robotics under the background of new engineering construction.
