Maze Solver with 3 ultrasonic sensors

i have to made a maze solver with 3 ultrasonic sensors..and i am using L293D motor Drive ..
i am stuck at cooding ..can anyone help me regarding Code

If it is a "maze solver", you must have some code, otherwise it is just a chassis with some sensors.

Why not post the code you have, and tell us what problems you are having with it (hint: "it doesn't work" is not a valid problem)
