The main strategy is based around the tower. We plan on driving straight towards the tower at the start of the game and then pushing it over our goal. While inspecting the tower, we noticed that there is hole at the bottom which would allow the balls to fall out if placed over our goal, so we decided it would be a great strategy to try and get all of the balls out of the tower by sliding it over our goal . While the ping pong balls our filling our goal, we will back up and block the opponents from scoring by positioning ourselves over their goal.
Advantages:
- Getting a lot of mass quickly and simply while we have an opportunity to block the opponents goal
- Allows us to have a very simple and sound vehicle without many moving parts
Disadvantages:
- Another team may be able to out push the tower from the opposing side
- Faster vehicles could score and block our goal before we are able to push the tower far enough
Machine concept:
Based on the strategy above, it is obvious that one huge requirement for our vehicle would be for it to be able to push the tower. This requirement inspired the overall tank-like appearance and functionality of the vehicle. We decided to go with treads to try and make sure we had a very small chance of sliding while at the same time having enough torque to push the tower.

Also, in order to push the tower at the lowest point possible, we needed an appropriately shaped plow. As you can see below, the plow has a notch in it to make sure there is an even amount of force distribution across the whole plow while in contact with the tower.

With the simplicity of our machine and strategy paired with the detailed calculations of torque and friction forces, I believe we have a great chance of winning.
