black line on a white surface.Its built from just electronic components.Its motors are a twin gear

control its motors.The circuit board,batteries for the interval timer,and the interval timer are
held on by a rubber band.Its body is a project box. 

Problems:The only problem I had was the photocells because when they recieved light reflected off
the floor they just kept running even when they got on the black line but I fixed this by adding a
interval timer.

Time to build:About a year on and off dew to the photocell problem but i fixed it.
