Abstract
Provided are a method and apparatus for ensuring a cleaning robot to return to a charge station. The method includes the steps of: (a) measuring a battery usable time, a running speed, and an actual return distance of a cleaning robot during a cleaning operation; (b) calculating an allowable return distance on the basis of the battery usable time and the running speed; (c) comparing the actual return distance with the allowable return distance; and (d) returning the cleaning robot to the charge station when the actual return distance is larger than the allowable return distance as a result of the comparison. Therefore, it is possible to prevent the cleaning robot from being not returned to the charge station, thereby providing convenience to a user.
