Problems solved by technology

[0006] Even though various methods are used as descriptors for feature points extracted from images, they cannot achieve good performance in cases where lighting or image changes are significant
Furthermore, adaptive drive control methods are not recommended if the input image cannot be used or errors occur in the drive control of the mobile robot when controlling the drive of the mobile robot

Abstract

The present invention relates to a control method for the localization and navigation of a mobile robot and a mobile robot using the same. More specifically, the localization and navigation of a mobile robot are controlled using inertial sensors and images, wherein local direction descriptors are employed, the mobile robot is changed in the driving mode thereof according to the conditions of the mobile robot, and errors in localization may be minimized.

Description

technical field [0001] The invention relates to a control method for positioning and navigation of a mobile robot and a mobile robot using the same. More specifically, the present invention relates to a control method for positioning and navigation of a mobile robot and a mobile robot using the method, which can use a local direction descriptor when controlling the positioning and navigation of a mobile robot using inertial sensors and images, according to Conditions of the mobile robot change the drive mode of the mobile robot and minimize errors in positioning. Background technique [0002] In recent years, thanks to advances in robotics, mobile robots that set paths and move by themselves have become available. Representative examples of mobile robots include cleaning robots that clean rooms or buildings, and receptionist robots that help find locations. In particular, the cleaning robot includes various sensors and driving units to clean indoor floors using a vacuum cl...
