| In this paper, the parametric modeling and simulation system of robots realized by us on PC is described. Parameterization of robots, real time of simulation, and easy development of programs are the main characteristics of the system.The system can display in 3D the robots with higher quality graphics on PC by adopting the solid model technology, and modify the model of robots according to the size given by users, so that the parametric modeling is realized under interactive mode. It realizes the graphics simulation of robots in kinematics in both articulatory space and Cartesian space, and it also realizes the animated simulation of trajectory of linear interpolation in point-to-point mode. The movement of robots can be realized by graphics teaching or programming.The paper has discussed such questions as the design and achievement of the simulation system of robots, which include the design of all modules such as parameter input, solid modeling, graphics teaching, data record, trajectory planning and so on.The system uses VBA (Visual Basic for Application) language, one of secondary development tools for AutoCAD, to program. It applies the ActiveX technology, puts forward that in the development of simulation system of robots, the matrix operation function of MATLAB language and strong graphics function of AutoCAD can be combined to make up for each other's short points, and the new method is demonstrated by a practical example. |
