Our strategy is focused around collecting the red balls on the upper ledge of the arena, and also collecting the yellow balls closest to our starting zone at the beginning and end of our execution. We selected this strategy because it has a high potential for scoring, as its calculated expected score was the highest. This strategy is also very simple and should be easy to implement. The strategy does not require a large amount of moving around the arena, as it is very centralized and is expected to make good use of the 90 seconds that are available.
Our machine will have two independently driven back wheels, with two caster balls on the front for stability (red). The arm and trap door at the front of the machine will be simultaneously controlled by the motor (blue) through a series of gears (green and yellow). As the arm is engaged (lowered to be able to rake balls down the slope), the trap door is lifted into the open position. When we move our machine around, we will raise the arm, which simultaneously closes the trap door.
