In this project you will build a simple circuit
by connecting a motor and a battery pack. Attaching a cork to the motor’s shaft makes
it vibrate. This is the same concept that makes cell phones
and video game controllers vibrate. You will attach your circuit to the body of
a robot made from recycled materials. Your challenge is to build a robot that can
move straight instead of just moving randomly or spinning in circles. To see written instructions for this lesson
