The Elenco Sound Reversing Car is a voice controlled robot car. The car is made up of transistors, capacitors, and resisters. In addition, a microphone and a few mechanical parts. The car will move forward until a sound is detected then the car moves backwards to the left for about two seconds before moving forward again. The two major components of the car are a microphone and a 15 degree pivoting front wheel, which position is dependent on the current direction of the car.  |
