Automatic battery charging system and method of robot cleaner |
摘要 |
An automatic charging system of a robot cleaner includes: a rotating plate (306) installed at a robot cleaner; an infrared ray receiving unit (304,305) mounted at the rotating plate (306) and receiving an infrared signal generated from a power supply unit (400) while being rotated; a microcomputer (303) for moving the robot cleaner to the power supply unit (400) on the basis of the received infrared signal; and an ultrasonic generator (308) for generating a stop signal when the robot cleaner nears to the power supply unit (400). A robot cleaner can be accurately and quickly moved to a power supply unit for a rapid charging operation, and a cost for implementing the robot cleaner can be reduced. |
