CONTROL METHOD FOR CLEANING ROBOTS
First Claim
1. A control method of a cleaning robot with a non-omnidirectional light detector, comprising:
- detecting a light beam via the non-omnidirectional light detector;
stopping the cleaning robot and spinning the non-omnidirectional light detector when the non-omnidirectional light detector detects the light beam;
stopping the spinning of the non-omnidirectional light detector and estimating a first spin angle when the non-omnidirectional light detector does not detect the light beam; and
adjusting a moving direction of the cleaning robot according to the first spin angle.

15. A cleaning robot, comprising:
-
a wireless signal detector to detect a first wireless signal; a motor to move the cleaning robot; and a controller to control the motor according to the first wireless signal, wherein when the wireless signal detector detects the first wireless signal and a strength of the first wireless signal is greater than a predetermined value, the controller determines whether the first wireless signal is output by a light generating device, and when the first wireless signal is output by a light generating device, the controller controls the wireless signal detector and the motor to let the cleaning robot move to the light generating device. - View Dependent Claims (16, 17, 18, 19, 20)
