Sorry I do not have any pictures of this yet. I just got batteries for my camera this morning before work. This consists of: 2x Fairchild QRD1114 Reflective Object Sensors 2x 10kΩ resistors 1x 180Ω resistor 2x PNP transistors 2x GM2 motors The idea behind this is pretty simple. When the QRD1114 sensor sees the reflected IR light it has emitted, the phototransistor closes and sends current through to the PNP transistor which then closes and sends current through to the motor.
