Abstract:In order to shorten the robot research and development cycle and speed up the application of the different configurations robot for complex curved surface parts,integrating parametric design idea into the entire design-to-application cycle,a parametric robot system was designed with various techniques including the inverse kinematics algorithm,modular design,3D printing technology,reverse technology,digital simulation technology,mechanical and electrical integration technology,et al.The parametric robot system can be used to quickly complete robot model design,path planning,visual programming,dynamics simulation,hardware assembly and testing by inputting the robot’〖KG-*3〗s geometric parameters.The parametric robot system is suitable for many industrial robots on the market,it can quickly program complex parts for laser processing,painting,shot peening,welding,and grinding,and easy to redevelop and expand applications.At last,a 3D printing parametric robot was manufactured by the system.A Chinese character was printed on a complex surface by the robot.The feasibility and efficiency of this scheme is proved.
