Preliminary sketch
Building Process
Originally we were going to make a lever combined with a wheel and axle that is attached to a screw. The screw, driven by the wheel and axle, would push the pencil up the lever and into the pencil sharpener. We realized that the lever was not needed and we replaced it with an inclined plane. The wheel and axle also kept moving off of the track so we added support. We attempted to increase the length of the axle but the extender prohibited it from moving as far as we needed so we got rid of it. Then we encountered distance again and fixed it. We also added a guide to stop the pencil from falling out of the track.
