Abstract

The invention discloses a positioning system of a mobile robot and a positioning method thereof. The positioning system comprises a base station. A dead reckoning positioning system comprises an angular rate sensor used for acquiring angle information of the mobile robot and a displacement sensor used for acquiring walking distance information of the mobile robot. An ultrasonic laser positioning system comprises an ultrasonic laser transmitting device arranged on the base station, an ultrasonic laser receiving device arranged on the mobile robot and an information processing system. The position coordinates of the mobile robot in the ultrasonic laser positioning system can be obtained through the information exchange between the ultrasonic laser transmitting device and the ultrasonic laser receiving device. A data fusion unit is used for the fusion of the angle information and the walking distance information in the dead reckoning positioning system as well as the fusion of two position coordinates in the dead reckoning positioning system and the ultrasonic laser positioning system. The elimination of accumulated errors in the dead reckoning positioning system is implemented by the ultrasonic laser positioning system through the data fusion unit.

Description

technical field [0001] The invention belongs to the technical field of mobile positioning of intelligent machines, and in particular relates to a positioning system and a positioning method of a mobile robot. Background technique [0002] With the rapid development of computer technology, microelectronics technology, and network technology, the key technologies of mobile robots have been studied more deeply, and some of them have matured. The working environment of mobile robots is unstructured and uncertain, so the requirements for robots are also higher. The positioning technology is a very key technical issue, and global positioning is an important function of mobile robots. Without this Without this function, any autonomous movement of the robot is blind. No matter what kind of robot it is, it always has to solve three problems during its movement, namely "where is it now?", "where are we going?", and "how to go?" In order to solve the above three problems. [0003] I...
