Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] It can be seen from the background technology that UWB technology in the prior art is applied to the field of positioning and navigation of robots. It can only locate the robot, but cannot judge the orientation of the robot. However, the orientation of the robot can be judged by means of an electronic compass. Once the electronic compass is affected by interference, its Indications will be less accurate. Based on this situation, the inventor of the present i...

Abstract

The invention discloses a positioning and navigation system and method of a robot and relates to the technical field of robots, aiming at solving the problem that the orientation judgment accuracy isrelatively low when a UWB (Ultra Wideband) technology is used for positioning and navigating the robot. The system comprises a plurality of labels, a base station, an electronic compass, a gyroscope and a controller. The method comprises the following steps: calculating a position coordinate of each label in real time and judging whether position coordinate data of each label is reliable or not; if so, determining a relation between a mounting position of each label and the orientation of the robot and combining the position coordinate of each label to determine an orientation angle of the robot; if not, judging whether detection data of the electronic compass is reliable or not; if the detection data is reliable, calculating according to the detection data of the electronic compass and determining the orientation angle of the robot; initializing the detection data of the gyroscope to be 0; when the detection data is not reliable, determining the orientation angle of the robot according to the detection data of the gyroscope. The positioning and navigation system and method of the robot can be applied to a positioning and navigation process of the robot.

Description

technical field [0001] The present invention relates to the technical field of robots, in particular to a robot positioning and navigation system and method, a storage medium, a robot, and a computer program. Background technique [0002] In the research of robot-related technologies, the positioning and navigation technology of robots is the core of the research, and it is also the key technology for robots to realize intelligence and complete autonomy. At present, the commonly used positioning and navigation technologies include VSLAM (English full name: Visual Simultaneous Localization and Mapping, Chinese name: Visual Simultaneous Localization and Composition), Wifi-SLAM (English full name: Wireless Fidelity-Simultaneous Localization and Mapping, Chinese name is: Wireless broadband simultaneous positioning and composition), UWB (full name in English: Ultra Wideband, Chinese name: Ultra Wideband), etc. [0003] Among them, UWB technology is widely used in the field of hi...
