for this vehicle with no sensors, i thought that if the vehicle had a bumper made of bearings, no matter what it ran into, it would just slip off of it and turn in a different direction. but since i only had two bearings, i designed a hinged front bumper system where once it hit an object, it would pivot the hinge and slide the front portion of the vehicle to the left or right (there is a missing third bearing on the right side).
