Application of Virtual Reality Technology in Teaching and Training System of Processing Industrial Robot

Abstract

In order to solve the problem of difficult teaching and slow teaching in the traditional teaching method of industrial robots, a virtual reality technology is proposed in the teaching and training system of industrial robots. The binocular vision module is fixedly connected to the end tool of the robot to reduce the limitation of teaching range. A hand-held teaching device with a feature plate and a position and pose measuring rod is designed to teach the position and pose of set points quickly. The least square method is used to calibrate the translation parameters of the end of the feature plate. The system collects the image of the feature plate of the hand-held teaching device through binocular vision module and processes the image to obtain the position and pose information of the end points; the pose information is converted to the robot base coordinate system to realize the robot teaching reproduction, and then the teaching reproduction test of 25 points in space is carried out. The experimental results show that the average error of the robot teaching position is 2.427 mm; after using mobile demonstration, the mean position error decreases by 25.3%. Conclusion. The application of virtual reality technology in the teaching and training system of machining industrial robot can improve the accuracy of teaching repetition.
