Abstract

A robot cleaner comprises a first light source, an optical sensor, a processing circuit and a second light source. The first light source emits first light. The optical sensor senses first optical data generated according to the first light. The processing circuit computes a height or an overhang height of an obstacle based on the first optical data. The second light source emits second light. The optical sensor senses second optical data generated according to the second light. The processing circuit determines whether the obstacle exists in the predetermined region or not based on the second optical data.
