Apparatus, method, and medium for localizing moving robot and transmitter
First Claim
1. An apparatus for localizing a moving robot and a transmitter using a sensor provided in the moving robot, the apparatus comprising:
- a motion controller to control the moving robot such that the sensor passes a plurality of measurement points by rotating the moving robot;
a distance measuring unit, which includes the sensor that senses predetermined waves generated from the transmitter, to measure distances between the sensor and the transmitter at the plurality of measurement points;
a rotational angle measuring unit to measure rotational angles of the moving robot at the measurement points; and
a location calculator to calculate location of the transmitter relative to the moving robot or location of the moving robot relative to the transmitter using input values including the measured distances, the measured rotational angles, and a radius of a circle determined by the sensor resulting from the rotation of the moving robot.

Abstract
Provided are an apparatus allowing a moving robot to localize a user, or localizing the moving robot from a fixed location, and a method and medium thereof. The apparatus includes a motion controller to control the moving robot such that the sensor passes a plurality of measurement points by rotating the moving robot, a distance measuring unit, which includes the sensor that senses predetermined waves generated from the transmitter, to measure distances between the sensor and the transmitter at the plurality of measurement points, a rotational angle measuring unit to measure rotational angles of the moving robot at the measurement points, and a location calculator to calculate relative locations using input values of the measured distances, the measured rotational angles, and the radius of a circle determined by the sensor resulting from the rotation of the moving robot.
