Abstract
A coordinates compensation method of a robot cleaner using an angle sensor compensates coordinates of the robot cleaner with reference to absolute coordinates of a recharging station, so as to improve robot cleaner's path following. The robot cleaner is in a standby mode at the recharging station, and moves to an operation area to perform a given job. The robot cleaner stops the given job upon determining an accumulative angle exceeding a predetermined level, and returns to the recharging station. Current coordinates of the robot cleaner are aligned with reference coordinates of the recharging station, and the robot cleaner moves to a previous spot where it was before it returns to the recharging station, and resumes the work from where it stopped.
