Circuit for Autonomous Model Vehicle

Not open for further replies.

Any help is greatly appreciated.

Basically i need to make a autonomous model car to hit a wall at an unknown distance and return to its original position.

My idea was to potentially have a capacitor charge and discharge 2 different motors, with a DPDT switch to reverse the polarity of the 2nd motor so that it reverses.

A circuit diagram would be incredibly helpful.

Thanks in advance.

Is this a school/college project?
What do you mean by 'charge and discharge two different motors'?
Why two motors?
What will the other motor do when the second one is reversed?

One is enough, multiple threads on the same subject causes confusion.
