Dual-direct-current motor micromouse system based on STM32 control

Abstract

The invention relates to a dual-direct-current motor micromouse system based on STM32 control, and belongs to the field of micro-robots. The dual-direct-current motor micromouse system comprises a master control chip, a detection module, an H-bridge drive module, a direct-current micromotor, a magnetic type encoder, a UART interface, a gyroscope, a human-computer interface, a power module, a PCB and the like. The detection module comprises six sets of infrared sensors and is used for detecting the wall distance and maze wall information. The gyroscope is used for correcting the posture of a micromouse in the turning process. Forward and reverse rotation, acceleration and deceleration of the direct-current motor are achieved through the H-bridge drive circuit. The rotating speed and locating information of the motor are obtained and fed back through the magnetic type encoder on the direct-current micromotor. The UART interface can be externally connected with a serial port or a Bluetooth module. The human-computer interface displays different work modes. The dual-direct-current motor micromouse system has the advantages that strong externally-mounted resources are provided by the master control chip, and the direct-current micromotor is used as a drive unit to improve the operating speed of the system. The system is small in size and light, time for completing tasks by the micromouse is lowered, operating stability of the micromouse is improved, and high practicality is achieved.

Description

technical field [0001] The present invention relates to a computer mouse system, in particular to a computer mouse system with dual DC motors controlled by STM32, more specifically, it relates to a miniature wheeled search robot controlled by STM32 with dual DC motors as the driving unit system. Background technique [0002] The computer mouse is an intelligent walking robot composed of embedded microcontrollers, sensors and electromechanical moving parts. It can automatically search the path and find the end point in the unknown maze, and find out the starting point of the maze according to the wall information recorded during the search process. The shortest path to the end, and then sprint from the start to the end at the fastest speed.

Problems solved by technology

[0003] At present, the main control chip used by domestic computer mice is the ARM processor with Cortex-M3 core produced by Luminary Company - LM3S615, five sets of infrared sensors, and the motor is a stepping motor, which is easy to control

But looking at the international computer mouse maze competition, the stepping motor computer mouse has been gradually eliminated due to its large size, heavy weight, and slow running speed. The performance of the LM3S615 main control chip at the same price is not as good as that of the STM32
