I recently began making a self drivable toy car at school. Although it is very primitive as of now, the concept is more or less working and very fun to work with. The car steers and drives itself, only by the help of the micro processor Arduino Uno I have programmed. The car orientates what is in front of it with the use of an ultra sound sensor located in the front. At school, I only had access to one sensor, that means the car is not able to "see" what is in the room very well, thus explains its primitive state.
