By taking the two kinds of aviation indutrrial robots SCARA/PUMA as a study object,its three dimensional (3D) model was converted into the STL file.By analyzing the STL file of 3D model,the law of data storage was studied.In the VS 2003 MFC，through loading the OpenGL graphical programming library,the robot model in the STL file was read and displayed.According to the robot modeling knowledge,the kinematics simulation was carried out,which realized the driver model with real-time display function.The method is certain of universal to kinematics analysis of the robot arm,which provides references for machining,manufacturing and maintenance of aviation products.
