Abstract

Disclosed is a mobile robot having a reflector including: a reflector detachably provided at a side of a front surface of a body of the mobile robot; and an infrared sensor including: an infrared transmitter emitting infrared light to the reflector and an obstacle; and an infrared receiver receiving both the infrared light reflected from a line on a floor after being reflected from a wing of the reflector and the infrared light reflected from the obstacle.

Claims

1. A mobile robot having a reflector, the mobile robot comprising:

a reflector detachably provided at a side of a front surface of a body of the mobile robot; and

an infrared sensor including;

an infrared transmitter emitting infrared light to the reflector and an obstacle; and

an infrared receiver receiving both the infrared light reflected from a line on a floor after being reflected from a wing of the reflector and the infrared light reflected from the obstacle.

2. The mobile robot of claim 1, wherein

the reflector includes:

a fan-shaped panel; and

a wing standing on the fan-shaped panel at a predetermined angle.

3. The mobile robot of claim 2, wherein

the wing stands at an angle between 20°

and 80°

based on the fan-shaped panel.

4. The mobile robot of claim 1, wherein

the infrared sensor is provided on the front surface of the body of the mobile robot.

5. The mobile robot of claim 1, wherein

the infrared light emitted at a predetermined angle from the infrared transmitter installed on the front surface of the body of the mobile robot to the wing of the reflector is reflected at a predetermined angle from the line on the floor, and is projected on the infrared receiver.

6. The mobile robot of claim 1, wherein

the infrared light emitted from the infrared transmitter installed on the front surface of the body of the mobile robot to left and right sides of the reflector is reflected from the obstacle, and is projected on the infrared receiver.
