Bumper Car

This little robot adds a touch-sensitive front bumper to the 5-Minute Bot. It will roam around your room and turn whenever it bumps into something.

Normally a touch-sensitive bumper would be made with a touch/pressure sensor, but since the standard Inventor kit doesn't include one, this design uses a simple trick to make one out of the color sensor.




The color sensor behind the bumper sees the
teal-colored beams when the bumper is pushed in.
