i need to build a vehicle that will go backward from a starting point and hit a wall ( which can be anywhere in the test track) by touching wall and comeback to as close to the starting point as possible
HELP pleases
What have you tried? Can you even make the thing move? Do you have some kind of switch to tell when you've slammed into the wall?
How will you know how far you have traveled? How will you assure that you start forward going the same direction you went backwards?
When is our homework due?
I'm sure that with a request like that folks on the forum will gladly put as much effort into this project as you appear to have done.

I'm nowhere near that tactful on a good day.

PS I am not allowed to use any sensor what so ever
so what can i use and what should i do
I don't know what a sensor is defined as in this context but if it's allowed I'd consider an encoder. You keep track of the number of steps until the encoder stops, which indicates the vehicle has hit the wall, and then reverse the same number of steps. A problem I can see with this is that if the wall is not perpendicular to the motion of the vehicle it may cause the vehicle to turn if it hits the wall with too much force.
