Prototype 2 Video

Description:

This second prototype is intended to be a follow-up of the first, elaborating specifically on the crank mechanism. Instead of using a chain for the prototype, a belt and pulley system is used on 2 axles. Spinning the top pully will also spin the bottom pully, and consequently, cause the “brush” on the bottom axle to spin as well. In the final product, Cogs and chains will be used to greatly increase the efficiency of the system in regard to power transfer.
