Multi-sensor-based trackless omnidirectional mobile robot system and control method thereof

Abstract

The invention discloses a multi-sensor-based trackless omnidirectional mobile robot system and a control method thereof. The system comprises a control panel, a PC (personal computer), an inertial navigation sensor, a two-dimensional code recognizer, a laser sensor, an odometer, a motor driver and an omnidirectional moving chassis connected with the motor driver, wherein the PC is used for transmitting control signals to the control panel, and the inertial navigation sensor, the two-dimensional code recognizer, the laser sensor, the odometer and the motor driver are connected to the control panel separately. The control board reads the data information of the inertial navigation sensor, two-dimensional code recognizer, laser sensor and odometer and obtains a corresponding control signal after control calculation and processing in order to control a motor to drive a mobile robot to run along a designated path. The control method achieves accurate locating by combining the odometer witha two-dimensional code on the basis of an inertial navigation algorithm. The method achieves position state correction and accurate locating of the trackless omnidirectional mobile robot and improvesthe adaptability and stability of the trackless omnidirectional mobile robot in a man-machine hybrid environment.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a multi-sensor-based trackless omnidirectional mobile robot system and a control method thereof. Background technique [0002] With the continuous improvement of industrial automation, mobile robot technology has developed rapidly and has been widely used in many industries such as logistics distribution, grass industry, pharmaceuticals, automobile manufacturing, machine fine chemicals, railways and military industries. In some logistics fields where humans and machines are mixed, in the process of carrying goods by mobile robots, due to the inaccurate range measurement of the odometer and the cumulative error in the measurement of the inertial navigation sensor, the positioning is inaccurate, and the adaptability to the mixed environment of humans and machines is not high. , steering flexibility also needs to be further improved.
