CLEANING ROBOT AND CONTROL METHOD THEREOF
First Claim
1. A cleaning robot, comprising:
- a roller unit comprising a plurality of rollers;
a sensing unit receiving a reflection signal and generating a detection signal according to the reflection signal;
a first control unit, wherein when the detection signal is less than or equal to a reference signal, the first control unit controls the traveling direction of the rollers according to the detection signal such that a distance between the cleaning robot and a wall is equal to a first distance; and
a second control unit, wherein when the detection signal is larger than the reference signal, the second control unit controls the traveling direction of the rollers according to the detection signal such that a distance between the cleaning robot and a wall is equal to a second distance larger then the first distance.

Abstract
A cleaning robot including a roller unit, a sensing unit, a first control unit and a second control unit is disclosed. The roller unit includes a plurality of rollers. The sensing unit receives a reflection signal and generates a detection signal according to the reflection signal. When the detection signal is less than or equal to a reference signal, the first control unit controls the traveling direction of the rollers according to the detection signal such that a distance between the cleaning robot and a wall is equal to a first distance. When the detection signal is larger than the reference signal, the second control unit controls the traveling direction of the rollers according to the detection signal such that a distance between the cleaning robot and a wall is equal to a second distance larger then the first distance.

9. A control method for controlling a cleaning robot comprising a first control unit and a second control unit, wherein traveling route of the cleaning robot is controlled by the first and the second control units, comprising:
-
activating the cleaning robot to receive a reflection signal; generating a detection signal according to the reflection signal; when the detection signal is less than or equal to a reference signal, the first control unit is enabled such that the cleaning robot maintains a first distance with a wall; and when the detection signal is larger than the reference signal, the second control unit is enabled such that the cleaning robot maintains a second distance with the wall, wherein the second distance is larger than the first distance. - View Dependent Claims (10, 11)
