Step-2: Making of Compound Eye (sensor) –
The Compound Eye sensor used in this bot is built using four IR LED’s and eight Photodiodes. The idea and design of the compound eye sensor was taken from ……………………….. Here is the link to his site ………….. . You can buy this sensor from Stores or make it yourself. From the reference of above site I had made a similar sensor with some modifications, the circuit I had used for my sensor is different from the original one and I had used Photodiodes instead of Phototransistors.
The circuit diagram of my (modified) sensor is below –
