To make up for the shortage of experimental devices for the emerging majors such as intelligent manufacturing and robot engineering,as well as the urgent needs in improving students' innovative and practical ability,we design a dual-arm cooperative teaching robot based on binocular vision.The mechanical part of the two arms is a symmetrical structure mounted on a big stable base to reduce manufacturing cost and coordinated grasping difficulty.In order to increase the accuracy of the robot terminal pose acquisition and thus improve the dual-arm cooperative grasp in both accuracy and stability,we design a teaching motion restoring algorithm and a reprojection error minimization algorithm.The upper computer of the system can drag and control the two arms to do programming teaching and action group experiments;and the robot can not only process images and conduct single-arm grabbing experiments under visual guidance,but also carry out motion analysis experiments,online programming,and open experiments of coordinated grabbing.The proposed system is cost-effective,rich in functions,highly integrative,and able of both drag teaching and open experiments,which is helpful to improve students' innovative and practical ability,therefore it is very suitable for promotion and application in the experimental teaching courses for intelligent manufacturing,robot engineering and other related majors.
