Abstract

A mobile robot motion control system based on a QT human-machine interaction interface and a motor servo system relates to a mobile robot platform and solves the problem that a conventional application rotor is uneasy to integrate, poor in universality and control performance, and is uneasy to debug during a failure or trial period because of closed overall structure. A motor feedback circuit is used for acquiring the pulse signal of a driving wheel of the robot, measuring the pulse frequency of the pulse signal, and transmits the pulse frequency to a controller. A motor driving module drivesthe driving motor of the driving wheel of the robot to rotates according to a motor control signal issued by the controller. A gyroscope acquires the angular acceleration data of the mobile robot andsends the same to the controller. The controller and a host computer realize data interaction. A motor control unit in the controller is used for acquiring the current pulse frequency sent by the motor feedback circuit of the corresponding driving wheel and obtains the motor control signal by PID operation according to the current pulse frequency and a preset signal of the motor.

Description

technical field [0001] The invention belongs to a mobile robot platform, and in particular relates to a motion control system technology of a mobile robot and a human-computer interaction technology for system debugging. Background technique [0002] With the advancement of robot technology and the continuous expansion of its application fields, mobile robots, as a branch of intelligent robots, are gradually entering our lives, and have brought new impetus to the related theories of robot autonomy and intelligence. At present, mobile robot technology is increasingly becoming a research hotspot in the field of robotics. It has great application prospects in fields such as restaurant service, warehouse management, express delivery, and factory material transportation. However, the currently applied robots are generally too large in size, which is not conducive to integration, poor versatility, and poor control performance; at the same time, because the overall structure is to...
