SYSTEM AND METHOD FOR AUTOMATICALLY RETURNING SELF-PROPELLED ROBOT TO RECHARGE UNIT Russian patent published in 2007 - IPC G05B19/00 G05B19/42 B25J5/00 B25J9/00 

Abstract RU 2306591 C1

FIELD: computer engineering.

SUBSTANCE: recharge unit emits infrared light from infrared unit in response to recharge request signal received from robot via wireless transceiver, and sends infrared radiation signal in accordance with infrared light radiation. The self-propelled robot communicates with the recharge unit using various data and sends recharge request signal to the recharge unit when accumulator charge level drops below a threshold level and moves back towards the recharge unit using image data input from camera unit as response to infrared radiation signal sent by the recharge unit. The robot has microprocessor for controlling robot movements for providing return to the recharge unit by processing data of infrared light position on picture introduced from camera unit when detecting infrared light presence in the picture.

EFFECT: accelerated return to recharge unit.
