中文摘要摘要：国外服务型机器人近年来不断创新，在机电一体化、高精度化、高速化等方面均有重大突破。国内服务型机器人通过不断引进国外先进技术，也取得不小进步，但在体育运动方面的服务型机器人发展和研究仍存在问题。本论文基于对现有移动机器人的研究及现代机械设计理论和手段，以提高乒乓球运动练习的效率、缩短在练习乒乓球时捡球的时间、满足市场需求为目标，进行乒乓球收集小车的设计，使其具有自动寻路、收集、传送等功能。论文所完成的主要工作如下。首先对乒乓球收集小车进行了总体方案设计，根据功能分析的结果将其分为收集模块、传送模块、行走与控制模块等功能模块，并对个功能模块进行了方案的设计和选择。然后，基于以上确定的方案，分别对各机构进行了详细的设计，包括尺寸设计和结构设计，绘制了相关的零件图和总装配图，并进行了标准件的选择及计算。本乒乓球收集小车前端采用滚筒配合挡板的结构，由直流电机驱动，将乒乓球收入机器内，然后通过传送通道传送到传送机构的入口，传送机构将乒乓球传送到收集盒中，收集盒可手动取出。关键词：乒乓球收集小车；收集；传送；自动行走ABSTRACTABSTRACT: In recent years，the innovation of service robots has been made consistently and major breakthroughs have been obtained in the mechanical and electrical integration, high-precision, high-speed and other aspects. In the mean while，great progress have been made in service robots through the introduction of foreign advanced technology. However there are still some problems need to be considered in developing and studying of service robots in sports field.In this thesis, ,a kind of table tennis collection machine/ car with automatic searching, gathering, transmission functions was designed to satisfy the market demands based on an existing mobile robot research and modern mechanical design theory. The main work of this thesis is as followings:Firstly, the overall scheme of the mechanical system of the table tennis collection car was put forward. According to the results of function analysis, the system was divided into following modules: gathering?modules, transmit modules, biped and control modules etc. Schemes for each function module were proposed and selected.Then, based on the above selected scheme, each module was designed in details, including the dimension design and structural design. The part drawings, component drawings and the assembly drawings of the table tennis collection machine were carried out. The table tennis collection machine was driven by baffle DC motor. The tennis balls were collected into the internal revenue of the machine from its front-end drum, then to catcher mouth b
