Graphical Simulation Technology Is Applied Research In Robot-assisted Teaching

Robot Assisted Education is corresponding to Computer Assisted Instruction. If a robot is applied in teaching process, its function of operation and demonstration is brought into fully play. It is of benefit for educating the ability of practicing byfinding and correcting students' operating error.The main research and achievements of this paper are as follows: Firstly, we introduce the concept of RAE and expatiate on the development, the meaning of the Natural Language Processing. And then we introduce the characteristics of Chinese syntactic parsing. Furthermore, we summarize the difficulties of Chinese syntactic parsing on the base of its implicit characteristics.Secondly, in this paper, Author has studied real-time modeling technology andreal-time controllable wander technology of scenes in virtual reality. We put forward a method of reading the 3D actual modeling data, reproducing the three-dimension modeling and realizing real-time controlThe system exploits an unit conversion interface of 3D graphic data organized in JDS type by Visual C++ and OpenGL, which can get the needful vertexes, texture mapping coordinate, material and illumination and so on from the modeling file built by 3DMAX, and then utilizes OpenGL to reproduce real picture in VC environment, and be able to achieve real time control.Thirdly, we has accomplished rebuilding 3D solid syntactic parsing tree, andthen we contrive looking on the syntactic parsing tree from difference views and controlling it, which can make the students watching the 3D visual graphics, deepening to understand the work principle of syntactic parsing.Fourthly, the paper makes deep researches on how to paint and display the Chinese character in the 3D scene created by VC++ and OpenGL. We put forward a few methods to realize it and provide a practical scheme to display 3D Chinese character. In the system, we program to illustrate the process of 3D solid syntactic parsing tree creating by OpenGL and Visual C++6.0, and to finish labeling Chinese character and English font on the node of the syntactic parsing tree.Lastly, we adopt displaying list to optimize the system, which accelerates thedisplaying speed and improve the performance of the system.
