    Yeah, sure. Find a circuit for a white line follower and reverse the actions that the sensors perform.

    You may be able to do this by swapping the position of the detector and the resistor (if its a voltage divider)

    Or swapping the 2 inputs over (or placing the detectors on the opposite side.

    Or reversing the connections to the motors (swapping left/right)

    You may have to tune the circuit a little to take account of the normal level of reflectance of the surface (i.e. light not dark)

    Edit: google "dark line follower"
