Final Challenge- 1

For this part of the challenge, Esther and I were introduced to the problem of making the MotorCar move straight. In the previous challenge, we made a program that would move the MotorCar forward, but it did not necessarily make it move straight. When we observed the Motocar go forward, we saw that it beared slightly to the right. In order to test the straightness, we used a tape line on the floor as a reference point and the ramp set up in the classroom.
Because our MotorCar beared to the right, we decided to add friction to the left wheel by pushing it inwards towards the motor. The result was that the MotorCar now beared towards the left. We had made too great of an adjustment.
When we added friction on both wheels, the MotorCar did not move straight at all. It looked like it was spinning to the right.

It was hard to find the right position of the wheels on the axle for the MotorCar to move straight.
