Abstract
Disclosed herein are a robot cleaner that is capable of reflecting an obstacle sensed by obstacle sensors on a local map and a control method and medium of the same. The robot cleaner includes an obstacle sensor to sense an obstacle, a memory to store a local map, and a control unit to calculate an obstacle position using the obstacle sensor and to reflect the obstacle position around the robot cleaner on the local map.
