APPARATUS FOR RETURNING OF ROBOT AND RETURNING METHOD THEREOF

摘要

An apparatus for returning of robot and a returning method thereof are provided, in which the apparatus for returning of robot includes a signal transmitter which is disposed on a charging station and transmits a single front signal and a plurality of distance signals including first, second and third distance signals, a signal receiver which is disposed on the robot and includes a plurality of receiving sensors to receive any one among the single front signal and one among the plurality of distance signals, and a controller which calculates an angle of the charging station by using one among the received single front signal and the plurality of received distance signals and controls the driving so that the robot can return to the charging station by using the calculated angle of the charging station.

1. An apparatus for returning a robot to a charging station, the apparatus comprising:
a signal transmitter disposed on the charging station to transmit a single front signal and a plurality of distance signals comprising first, second and third distance signals in which a respective transmission distance of the plurality of distance signals consecutively increases; a signal receiver disposed on the robot and comprising a plurality of receiving sensors to receive the single front signal and the plurality of distance signals; and a controller configured to calculate an angle of the charging station by using any among the single front signal and the plurality of distance signals as received, and to control the driving of the robot so that the robot returns to the charging station using the calculated angle of the charging station, wherein the controller controls the robot to drive away from the charging station when the first distance signal is received by at least one among the plurality of receiving sensors provided on the robot, or for the robot to drive toward the charging station when the third distance signal is received, the controller controls the robot to perform front-turn driving toward a direction corresponding to a preset angle based on a direction of the charging station and searches the front signal when the second distance signal is received by at least one among the plurality of receiving sensors, and the controller controls the robot to drive toward the direction of the charging station and to connect to the charging station when the front signal is received by at least one among the plurality of receiving sensors.
