Aiming at the problems of the existing robot teaching system,such as complex operation,high programming difficulty and need to control the robot,a non-contact and non-programming robot teaching method based on laser positioning technology was proposed.The teaching pen was used instead of the robot end tool to draw the teaching trajectory,the teaching path and action of the teaching pen were obtained through laser positioning technology,and the control trajectory of each joint was obtained through robot inverse kinematics solution and trajectory planning,so as to realize rapid non-contact and non-programming robot teaching.Finally,by building a truss six-axis robot hardware and software system,the non-contact and non-programming teaching of the robot based on laser positioning technology was realized,and the feasibility of the proposed teaching method was verified.This teaching method simplifies the teaching process,reduces the safety risks associated with robot manipulation,does not require operators to have programming skills,and makes robot teaching work adaptable and widely applicable.
