This paper designs a detection system of mine robot obstacle based on MCU. This system is mainly composed of the following parts: the ranging module is used in ultrasonic ranging sensor; information transmission module is used in Bluetooth wireless transmission; control of the whole system using STC89C52 Microcontroller control module operation; power module is powered by a battery of two DC motor control robot action. Programming the control system of STC89C52 Microcontroller with KEIL software. The system first through the ultrasonic ranging sensor for monitoring the obstacles, such as no obstacle system conveys information through the communication module, and the driving motor is the robot forward; obstacles such as discovery, calculate the distance between the robot and obstacle distance, spread information, the controller drives the motor with obstacle avoidance, to detect whether there is in front of obstacle. This system operation cycle. When the system is running, we require the system must be on the front obstacle distance to make accurate judgments, to avoid obstacles, path selection can also be measured to detec
