摘要多足机器人是一种模仿昆虫步行方式的机器人,多足机器人依靠独立的具有多自由度的腿部提供动力,以一定的步行姿态实现机器人的行进。区别于传统的轮式和履带式机器人,多足机器人能在地形不规则和崎岖不平的环境中行走,它的环境适应性更强,可以完成宇宙探索、救难等复杂任务。本论文论述了八足机器人的概念、优缺点和应用前景,以及八足机器人的工作原理。并根据给定设计要求,确定八足机器人结构设计方案,尤其是其腿部的结构设计方案。运用三文绘图软件建立机器人的整体模型,着重细化机器人的腿部模型。通过运用ADAMS仿真软件对虚拟机进行静力仿真,计算、校核八足机器人腿部重要零件的结构特性及安全性。对虚拟机进行动态仿真,测量、分析八足机器人足部的运动特性。8091

Title The analysis of foot structure for an eight-legged robot
Abstract
Multi-legged robot is a kind of robot which imitates insects, its motive power comes from the legs with multiple degrees of freedom, and it can walk with a particular posture. Different from the traditional wheeled and tracked robots, multi-legged robot can walk in the irregular and rugged environment. Its adaptability to the environment is great. It can complete the complex tasks of space exploration, rescue, etc. This essay discusses the concept, advantages, disadvantages, application prospects and the working principle of the robot. According to the given requirements, the author needs to help design the structure of eight-legged robot, and then finish the design of the structure about its legs. After that, the writer Uses 3D graphics software to create the overall model of the robot and the model of the robot's legs is the main point. By using ADAMS,the author will do some static simulation for the virtual machine, calculating and checking the structural characteristics and safety of the important parts of the eight-legged robot legs. And some dynamic simulation will be done for the virtual machine, to measure and analyze the motion characteristics of the eight-legged robot foot.
