Aiming at dangerous special environment, a control system for eod robot which could be used to replace manual operation was designed.In this system, DSP was used as central processing core, six servo motors with aluminum alloy were used to complete hardware structure of the mechanical arm. The DSP enhanced PWM module was used to drive the servo motor. Host computer was controlled by PC. Instruction was sent to SCI by the serial testing software,so as to control mechanical arm and can realize multi-angle movement. The experimental results show that the control system’s precision is high,the adjustment velocity is fast,the mechanical arm has strong bearing ability and can accurately hold dangerous goods and put them in isolation box.
