3、id development of mechanical manufacturing technics, the application of robots is expanded from cars to other fields progressively. In all types of robots, the joint-type robot which is composed of the simulation of human arms, has great advantages such as compact construction, little space accounte
4、d, and wide motion space, is one of the most widely used robots.In particular, flexible bio-robot which is composed of flexible joints is applicated and needed more and more prominent in the field of service and rehabilitation. The focus of this subject is the machanism design and its feasibility an
5、alysis of the pneumatic muscle arm joints, and then finish the mechanical design of the machanism parts of anthropomorphic robot joint. Because research history of pneumatic muscles flexible joints is short, information is little, the dynamic characteristics of the muscle is still under study, this
6、subject has certain difficulty, and pay attention to the satisfaction of the static index in the course of studying. The problem this passage mainly resolves-mechanical design and simulation. The main content of this subject: (1) Design the joint structure of pneumatic manipulator; (2) Parametric design of the joint structure; (3)Using simulation software to simulate structure in order to improve the mechanical design until obtain the satisfactory result. Goal: Achieve the optimized d
