AI Technical Summary

Problems solved by technology

[0007] However, according to the prior art, the estimation of 3D coordinates is inaccurate due to the use of side landmarks
In addition, when errors are accumulated due to wheel slippage, the position error may be very large, so the position can only be recognized using a camera, but there is a problem that it is difficult to extract features in a dark environment

Abstract

The invention relates to a mobile robot and a position recognition method thereof. The mobile robot includes: a position recognition module, which extracts a straight line during travel, and uses the extracted straight line to identify the position; a second position recognition module, which can reflect the image information obtained from the surrounding area and reflect the first position recognition The location identified by the module to finally identify the location.

Description

technical field [0001] The invention relates to a mobile robot and a position recognition method thereof. Background technique [0002] Typically, robots are developed for industrial use and serve as part of factory automation. Recently, the field of application of robots has been further expanded, and medical robots, aerospace robots, etc. have been developed, and household robots that can be used in ordinary homes have also been manufactured. [0003] A robot cleaner, which is a representative example of the home robot, is a home appliance that sucks in surrounding dust or foreign matter while autonomously traveling in a predetermined area and cleans it. Such robot vacuum cleaners generally have rechargeable batteries, and have obstacle sensors that can avoid obstacles during travel, so that they can clean while traveling autonomously. [0004] Applied technologies utilizing mobile robots, in particular robotic vacuum cleaners, have recently been developed. [0005] Kor...
