Abstract

The embodiment of the invention is suitable for the technical field of robots, and discloses a mobile robot positioning and navigation method and device, a mobile robot and a computer readable storagemedium. The method comprises: acquiring a grid map of a target area, wherein an ultra-wideband base station is preset in the target area, and an ultra-wideband label is carried on the mobile robot; determining a first ultra-wideband base station coordinate of the ultra-wideband base station under a robot grid map coordinate system; obtaining absolute position point information of the robot in thegrid map according to the first ultra-wideband base station coordinate and an ultra-wideband positioning signal of the mobile robot; and based on the grid map, performing robot positioning navigationthrough the absolute position point information and sensor signals, and the sensor signals comprising at least one of laser radar signals, inertial navigation signals, odometer signals and visual sensor signals. According to the embodiment of the invention, the robot is assisted in positioning and navigation through the UWB positioning signal, and the positioning and navigation accuracy of the mobile robot can be improved.

Description

technical field [0001] The present application belongs to the technical field of robots, and in particular relates to a positioning and navigation method and device for a mobile robot, a mobile robot and a computer-readable storage medium. Background technique [0002] With the continuous development of robot technology, the application of robots is becoming more and more extensive. [0003] At present, if a mobile robot wants to move freely and safely in indoor situations, it needs to know its position on the map and the map position of the target point at all times. The positioning and navigation methods of mobile robots include inertial navigation, laser radar positioning and navigation, and visual positioning and navigation. There are also multiple sensor data for positioning and navigation. For example, sensor data such as laser radar, odometer, and inertial navigation are integrated for positioning and navigation. . [0004] However, in scenarios such as airports, wa...
