Application of QR Code for Localization and Navigation of Indoor Mobile Robot

open access: yesIEEE Access, 2023
Localization is essential for the autonomous navigation of a mobile robot. Because the error of the internal dead-reckoning localization increases with time, the localization error should be corrected periodically using external environmental information.
