Problems solved by technology

However, when the robot uses the principle of inertial navigation to measure its own angle, due to the cumulative error, the robot's own positioning will be inaccurate, which will affect the working efficiency of the robot.

Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention. It should be understood that the specific embodiments described below are only used to explain the present invention, not to limit the present invention.

[0019] The robot described in the present invention is an intelligent cleaning robot (such as a sweeping robot or a mopping robot), and the robots mentioned in the following embodiments all refer to intelligent cleaning robots. These robots can rely on a certain amount of artificial intelligence to automatically walk on certain occasions. There are various sensors on the body of the robot, which can detect the walking distance, walking angle (that is, the direction of travel), the state of the body and obstacles, etc. If it encounters a wall or other obstacles, it will turn by itself, and according to different settings, And take different r...

Abstract

The invention relates to a robot straight-side-based positioning method. The straight side passing along the edge of the obstacle is recorded as the positioning side in the walking process of the robot, and the correction data can be provided for error correction when the later walking error of the robot is high and the positioning conditions are met so that the situation that accurate walking andnavigation cannot be performed because of increasingly high walking error of the robot can be avoided and the positioning accuracy and the walking efficiency of the robot can be enhanced.

Description

technical field [0001] The invention relates to the field of robots, in particular to a straight edge-based positioning method for a robot. Background technique [0002] With the development and maturity of gyroscope technology, robot positioning technology based on inertial navigation has gained more and more applications. For example, an indoor cleaning robot can provide an accurate angle through a gyroscope, coupled with odometer data, to achieve indoor inertial navigation. The advantage of this type of navigation technology is that it only needs cheap gyroscopes and odometers, and does not require relatively expensive sensors such as lasers, vision, or wireless positioning. However, when the robot uses the principle of inertial navigation to measure its own angle, due to the cumulative error, the self-positioning obtained by the robot will be inaccurate, which will affect the working efficiency of the robot. Contents of the invention [0003] In order to solve the ab...
