The utility model discloses an automatic crimping tool embedded control system for a high-voltage live-line work robot. The system comprises a main controller that is connected with an AD sampling module; and the AD sampling module is connected with a current sensor. The main controller is connected with a digital quantity collection module that is connected with an infrared obstacle avoidance sensor. The main controller is connected with an emulator by an emulator interface; an input terminal of a motor drive circuit is connected with a PWM output port and a DIR direction output port of the main controller; and the output terminal of the motor drive circuit is connected with a motor. The main controller is also connected with a serial port drive module that is connected with a wireless emission receiver. In addition, the main controller is also connected with an external key acquisition module that is connected with an input device. According to the technical scheme, stepless speed changing can be carried out; forward and backward rotation controlling can be realized; and the control is flexible and reliability is high. On the basis of the modularization design, various peripheral interfaces are arranged and connection with various sensors and drives are carried out conveniently, so that the function of the system is powerful.
