Today for our EPro8 challenge, my group built a ‘Caveman Car.’ A Caveman Car is a car that manually moves by itself, our car is rubber band powered with a rubber band around the reel, resulting in the ‘Caveman Car’ moving. The Caveman Car had to have a roof to protect the caveman from the rain, a seat where the caveman will sit, and the rubber band powered motor. Before we made the frame of the car, we did a prototype to find out how the car would be powered. It was a challenge to make the Caveman Car move because my group and I had to make it lighter, but Miss George told us to make the aluminum rod longer so the car would drive farther. In the end, we successfully built the ‘Caveman Car’.
