Embodiment Construction

[0048] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] At present, the positioning algorithm for indoor absolute positioning cannot well adapt to the dynamic environment with large traffic. In this environment, the map is constantly changing, and positioning is difficult. , based on this, a robot positioning device, method and robot provided by the embodiments of the present invention can realize indoor absolute positioning of the rob...

Abstract

The invention provides a robot positioning device, method and a robot. The device comprises a first ultrasonic sensor, a second ultrasonic sensor, a first ultrasonic emission source, a second ultrasonic emission source and a positioning module. The first ultrasonic sensor and the second ultrasonic sensor are arranged on the robot, and the first ultrasonic emission source and the second ultrasonicemission source are arranged on a robot charging pile. The first ultrasonic emission source is used for emitting first ultrasonic signals; the first ultrasonic sensor is used for receiving the first ultrasonic signals and obtaining first location information; the second ultrasonic emission source is used for emitting second ultrasonic signals; the second ultrasonic sensor is used for receiving thesecond ultrasonic signals and obtaining second location information; and the positioning module is used for obtaining positioning information of the robot according to the first location informationand the second location information. According to the robot positioning device, method and the robot, absolute positioning of the robot in a dynamic environment with large indoor human traffic can berealized.

Description

technical field [0001] The present invention relates to the field of robot positioning, in particular to a robot positioning device, method and robot. Background technique [0002] The positioning of the robot is the robot's cognition of its own position, which is the premise for the mobile robot to complete the construction of the map and the path planning. Specifically, it is to obtain an accurate estimate of the current pose through algorithm processing based on input information such as maps, position estimates, and sensor observations. [0003] Robot positioning relies on external sensors to obtain information such as GPS, global road signs, and global maps, which is absolute positioning. The application of absolute positioning in outdoor and indoor environments differs: GPS is widely used for absolute positioning in outdoor environments, while in indoor environments, lidar, vision sensors, and ultrasound are usually used to detect environmental information and match t...
