3.ir led and ir photo diode :2 pair
4.470 ohm resistor :4
5.diy robot chassis
Hi welcome to the second part of five part robot series. As youcan see i am using the same circuit that i used in Light following robot.i just added relay switch in each channels output.
I build a sensor circuit with a pair of ir photo diode and ir led ( for each channel).
Here is the diagram of the circuit.in this circuit you can see that i motors are powered by separate battery.
Now final assembly of robot
And now lets test it.
This is not the most sophisticated robot but i am sure this is the easy to make robot.
We have a be nice policy.
Please be positive and constructive.
