In the Robotics Activity we did we had built a car out of legos and used it for the experiment. We started with measuring the diameter of the wheels. We found the circumference of the car and measure the speed and rotation of the wheels by connecting the car to the computer to collect the data. We recorded the wheel rotation, the time it took to rotate and the distance it went. At lower powers the car struggled to move and at higher speeds it skidded to stop, which could explain the discrepancies in the data.
