Abstract
A method and apparatus estimating a position of a moving robot are provided. The method includes receiving a primary signal and a secondary signal transmitted from a predetermined signal transmitter using a sensor, on a moving robot, that receives the primary signal and three or more sensors that receive the secondary signal; calculating a transmission distance from a sensor that receives the secondary signal using time information extracted from the primary signal; and calculating a position of the signal transmitter from the distance, wherein the secondary signal comprises first and second secondary signals and each sensor that senses the secondary signal determines whether to amplify the second secondary signal based on the result of the measurement of the first secondary signal.
