Abstract: An automatic charging system of a robot cleaner includes: a rotating plate installed at a robot cleaner; an infrared ray receiving unit mounted at the rotating plate and receiving an infrared signal generated from a power supply unit while being rotated; a microcomputer for moving the robot cleaner to the power supply unit on the basis of the received infrared signal; and an ultrasonic generator for generating a stop signal when the robot cleaner nears to the power supply unit. 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.

Abstract: In the conventional cleaning robot, by mainly using each supersonic waves sensor having a sensing range as null30null in consideration of an appropriate sensitivity, when four supersonic waves sensors are installed at a cleaner main body, a sensing range as 240null is obtained, and accordingly it is impossible to observe surroundings of the cleaner thoroughly. In order to solve the above-mentioned problem, a position information recognition apparatus for a cleaning robot in accordance with the present invention includes a fixed plate installed at a cleaner main body; a main motor fixedly installed at the fixed plate in order to generate a rotational force; a rotational cylinder combined with a rotational axis of the main motor so as to be rotated at a certain angle; and plural position information sensors installed at the rotational cylinder at a certain angle in order to sense surroundings. By installing several supersonic waves sensors performable left/right rotation at regular: intervals, observation region can be greatly increased, and accordingly it is possible to improve efficiency by eliminating unnecessary rotational motion of the cleaner main body in position recognition and distance compensation.
