Multiple Servo Control System Design of Coal Mine Rescue Robots

This article puts forward a parallel control method of multiple servo based on the mine search and rescue crawling robot with 6 foot, which can realize single control for each servo. In order to identify servo angle conveniently, a representing method of the servo angle is proposed when access the servo angle. Hardware circuit is composed of AT90S8515 and 74HC595, which can save a lot of ports for SCM. The 24 road PWM wave is as an example in programming and the simulation results are given in the last.
