Edge Blocker Robot Concept

Edge barrier robot's concept line is similar to a follower. In these types of robots, we generally use light behavior on the black and white surface. When light falls on a white surface, it is almost full reflected and is absorbed by the black surface in the position of light in the black surface. This behavior of light is used in a follower robot as well as in the shielding robot.





Here we have used the IR transmitter and the receiver which is also called the photo diode, which is used to send and receive light. IR transmitted infrared illumination When infrared rays fall on any surface except for dark or more dark surfaces, it reflects the layer and is drawn by photodiode and produces some voltage changes. When the IR light falls on the black surface, the light from the black surface is absorbed and no ray does not reflect back, resulting in no light or ray of the photo diode.
