In this paper RoboCup Mid-size Robot are the object of study from the two sides of the robot system and the system of multi-robot cooperation, the main research results are as follows: First, this paper reasearches the problom of the hardware and software architecture of Mid-size robots. According to the real-time requirements of the competition, the paper designs the mechanism of omni-direction wheels, which achieves a great improvement on the traditional mechanism of two wheels robot, and a more flexible response. This mechanism can adapt well to the increasingly rapid pace of the competition. In allusion to the mechanism of omni-direction wheels, this paper designs the electrical control system of three nodes in the bottom, which could communicate fast to the laptop with serial port and match the real-time requirements well. According to the problom of hitting power and speed of robot when shooting, this paper designes a motor-driven tongue-shaped spring shooting mechanism, which has a simple mechanical structure, smaller space in size and simple control circuit. This shooting mechanism meets the real-time requirements of the competition better.

本文以RoboCup中型机器人作为研究对象，分别从机器人自身系统和多机器人协作系统两个方面进行了研究，主要研究成果如下：首先，研究了中型机器人的软硬件体系结构问题，针对实时比赛的要求，提出了万向轮机构的设计方案，大大改进了传统两轮机器人结构，动作反应更加灵活，该机构能够很好的适应节奏越来越快的比赛；针对万向轮机构，设计了3节点的底层电机控制系统，它可以通过串口与上层笔记本电脑快速通讯，能够很好的实现实时工作要求；针对机器人射门时击球力量和速度的问题，设计了一套电机驱动的舌形弹簧射门机构，机械结构简单，占用空间体积小，控制电路简单，较好的满足了比赛中实时射门的要求。
