Robot system
First Claim
1. A robot system including a beacon with a transmitting part to transmit light to determine location, and a mobile robot with a receiving part to receive the light,the beacon comprising:
- a rotation driving part to rotate the transmitting part; and
an encoder to add phase information regarding rotation of the transmitting part to the light, andthe mobile robot comprising;
a location determiner to determine a location of the mobile robot based on the phase information of the light received by the receiving part,wherein the rotation driving part outputs information on a phase shift of the transmitting part relative to a reference direction of the rotation driving part of the beacon in accordance with the rotation of the rotation driving part, andwherein the location determiner determines the location of the mobile robot based on a displacement of the mobile robot, and the phase information received by the receiving part.

Abstract
A robot system including a beacon provided with a transmitting part to transmit a light for location determination, and a mobile robot provided with a receiving part to receive the light. The robot system further includes a rotation driving part to rotate the transmitting part about a predetermined axis; an encoder to add phase information regarding how much the transmitting part is rotated by the rotation driving part with respect to a reference direction to the light; and a location determiner to determine a location of the mobile robot based on the phase information of the light received by the receiving part. Accordingly, a robot system is provided, which can precisely determine a location of a mobile robot regardless of external environmental conditions, distance, and reduction of cost by using a few transmitters.
