Co-ordinate compensation method for robot cleaner, involves stopping robot cleaner when judging that accumulative rotation angle exceeds preset level and returning cleaner to recharge station for compensating actual co-ordinates

摘要

The robot cleaner is maintained in a standby mode at a recharge station and moved to operation area. The robot cleaner is stopped from performing the job, when judging that an accumulative rotation angle exceeds a preset level. The cleaner is returned to the recharge station to compensate actual coordinates with reference coordinates. The cleaner is returned to a previous spot for resuming the job. An independent claim is also included for robot cleaner system.
