Performance Predictions More contact area on drive wheel means better grip Smaller drive wheel requires less torque A rough estimate for the time it will take would be about 20 seconds

Reflections We changed our design to have more rope to drive wheel contact We used aluminum because it was light and strong Hardest part for us was getting a drive wheel Over all we spent about $35 on materials In the future we would implement lighter building materials
