Mobile robot
First Claim
1. A mobile robot system comprising:
- a mobile robot includingcontrol means for controlling operation of the robot,driving means for moving the robot according to control of the control means, andinfrared signal transmitting/receiving means for transmitting and/or receiving an infrared signal in the course of travel of the robot; and
position correcting means separated from said mobile robot for receiving the infrared signal from the infrared signal transmitting/receiving means and for sending an intrinsic code signal to the infrared signal transmitting/receiving means, said position correcting means includingan infrared receiving unit for receiving the infrared signal transmitted from the infrared signal transmitting/receiving means;
a trigger generating unit for generating a trigger signal according to the infrared signal received at the infrared receiving unit;
a code establishing unit for receiving a voltage supplied from a power supply unit to thereby output intrinsic code data characteristic of the position correcting means as predetermined by a user;
a code modulating unit for modulating the intrinsic code data output from the code establishing unit; and
an infrared transmitting unit for receiving and amplifying the intrinsic code signal modulated by the code modulating unit to thereby transmit the amplified intrinsic code signal to the infrared transmitting/receiving means,said mobile robot further including distance detecting means for detecting a separation distance from the position correcting means in order to output separation distance data detected therefrom to the control means, said control means correcting a position error on the basis of said intrinsic code signal and said separation distance data.

Abstract
A self-propelled robot for performing jobs while travelling along a route, and more particularly to a mobile robot for correcting a position error generated in the course of movement of the robot to movably control the robot to a targeted area, including a control unit; a driving unit for moving the robot according to control of the control unit; an infrared signal transmitting/receiving unit for transmitting and/or receiving an infrared signal during travel of the robot according to the driving unit; a position correcting unit for receiving the infrared signal from the infrared signal transmitting/receiving unit to output an intrinsic code signal to the infrared signal transmitting/receiving unit, so that a position error data generated during the travel of the robot can be corrected by a predetermined position coordinate data; and a distance detecting unit for detecting a separated distance from the position correction unit to output a separted distance data detected therefrom to the control unit, so that the position error can be corrected.
