Abstract
A docking station for a robotic cleaner may include a housing, at least one charging contact coupled to the housing, and at least three optical emitters disposed within the housing. The at least three optical emitters may include a first optical emitter configured to generate a first optical signal within a first field of emission, a second optical emitter configured to generate a second optical signal within a second field of emission, and a third optical emitter configured to generate a third optical signal within a third field of emission. The third optical emitter may be disposed between the first and second optical emitters. The first, second, and third optical signals may be different from each other. The third optical signal may be configured to guide a robotic cleaner in a direction of the housing.
