Abstract: This paper deals with the computer structure of a distributed control system for a quardruped walking robot.It details a new kind of muhiprocessors connection structure based on distributed mail boxes and a method of information transmission between processors based on information package which not only maintain the advantages of shared memory structure but also avoid the bottle-neck problem in the single shared memory system.The design efficiently promotes the abilities of parallel processing,real time control as well as the feasibility of the control system.
