Strategy & Machine Concept

     We settled on a strategy that focuses on collecting balls from the base of the tower. We wanted to do this with a machine that can mostly just position itself in front of the tower and then sweep many balls under it continuously, guiding them to the goal without moving.

Our final concept does this with a sort of "waterwheel" device on the front, and a fence that extends from the back with a rack and pinion mechanism.

We created a Solidworks model that shows clearly how the modules of the machine will work together and how the motors and power transmission methods will function.

We are very enthusiastic about this design and look forward to building it.
