Team Challenge IV

Things That Go Bump

Goal:  Build and program a car that will travel in a straight line until it hits a wall, reverses direction, travels until it hits another wall, and then stops.

Challenge Questions:

1.      Describe or sketch the bumpers you built. Do they work if the car hits the wall at an angle instead of head on?

2.      Did you use one or two touch-sensor ports? If you used one port, how could you change your program so that it uses two different ports? If you used two, how could you change your program so that both touch sensors use the same port?
