Cleaning robot having carpet detector and method of detecting carpet boundary using the same
First Claim
1. A cleaning robot having a single carpet detector to detect a state of a floor, comprising:
- a main body;
a driver fixed to the main body to move the robot; and
the single carpet detector detecting a carpet when the robot is driven by the driver, the carpet detector including a single contact part in contact with the carpet when the robot is moving on the carpet, and a single sensing part to sense motion of the contact part generated by the contact with the carpet,wherein the cleaning robot includes the single carpet detector to determine the state of the floor,wherein the sensing part includes a rotation sensor sensing rotation of the contact part.

Abstract
A cleaning robot having a carpet detector and a method of detecting a carpet boundary using the same, in which the presence of the carpet on a floor is detected. The cleaning robot having a carpet detector includes a main body, a driver fixed to the main body to move the robot, and the carpet detector detecting a carpet when the robot is driven by the driver. The method of detecting a carpet boundary includes detecting a carpet using respective carpet detectors fixed to both wheels of a robot, obtaining a moving distance of the robot for an interval between times at which the respective carpet detectors detect the carpet, and calculating a boundary direction of the carpet with respect to a moving direction of the robot using the moving distance and the interval between the times at which the respective carpet detectors detect the carpet.
