Control method for cleaning robots
First Claim
1. A charging station for a cleaning robot, comprising:
- an infrared (IR) transmitter to output a first IR light beam with a scattering angle 2θ
, wherein the IR light beam comprises a second boundary and a first boundary, and the IR transmitter is offset at the angle θ
to make the first boundary is substantially perpendicular or perpendicular to the charging station and the cleaning robot moves to the charging station along the first boundary; and
a controller to control the IR transmitter, wherein when the controller determines that the cleaning robot is near to the charging station, the controller controls the IR transmitter to output a second IR light beam.

Abstract
An embodiment of the invention provides a charging station for a cleaning robot. The charging station includes an IR transmitter and a controller. The IR transmitter outputs a first IR light beam, wherein the IR light beam includes a second boundary and a first boundary which is substantially perpendicular or perpendicular to the charging station and the cleaning robot moves to the charging station along the first boundary. The controller controls the IR transmitter to output the first IR light beam or a second IR light beam. When the controller determines that the cleaning robot is near to the charging station, the controller controls the IR transmitter to output the second IR light beam.
