机械式助教机器人的设计

摘要

In view of some problems in classes such as too little communication between teachers and students,incon-venient information communication,and not good enough teaching quality,etc.,the mechanical teaching assistant robot is designed based on the principle of mechanical-electrical integration.The robot can realize mutual transformation of imparting knowledge,searching information,and mechanical equipment.By applying the complex articulated mechanism,hoisting mechanism for demonstration table,and desk telescoping mechanism,mutual transformation between movable multi-media, deformation teacher's desk,and movable 3D demonstration table is realized.The parameter design for the virtual prototype is accomplished with SolidWorks as the design platform.Optimal design is performed by Matlab to work out related parameters for the desk telescoping mechanism.The dynamic simulation analysis and modal analysis are performed for hoisting mecha-nism for demonstration table through ADAMS,which verifies design reasonability of the structure and feasibility of function realization.%针对目前课堂师生沟通交流过少、信息传达不便、教学质量欠佳等问题，基于机电一体化的理念，设计出一种机械式助教机器人。该机器人可实现传授知识、搜集信息和机械设备的相互转化。综合应用复合铰链机构、演示台升降机构和桌面伸缩机构，实现移动多媒体、变形讲桌、移动3D演示台的相互转化。同时以SolidWorks为设计平台完成虚拟样机的参数化设计，利用Matlab优化设计出桌面伸缩机构的相关参数，通过AD-AMS对演示台升降机构进行动力学仿真分析和模态分析，验证了该机构设计的合理性和功能实现的可行性。
