IR sensor cicuit for maze solving robot

[govinho88]

Hi guys,

I am trying to build a maze solving robot for a local competition.I have decided to use IR sensors to detect the walls as I plan to solve the maze by the wall following algorithm. However, I dont really know the circuit for a wall detecting IR sensor...I have found some on the net but those circuits are for the line following robot.Can anyone please help me with the Circuit...pls

I have built two circuits for IR detection, and have used them many times on robots:

Re:

I have a circuit maybe ill post it tommorow coz im at work right now.
I suggest you use the sonar sensor for more accurate result.
