To mount our ball, we needed a solution that would allow for free motion of the ball once it is hit, similar to how a golf tee normally falls after impact from a club. With tips from the TAs, we chose to source rubber golf tees for our solution. This solution ultimately allowed us to calibrate the position at which we wanted our ball to be hit, and it also ensured that we would have a robust method to hold our ball. Additionally, the team printed additional 1.1" standoffs in order to optimize the height at which the end effector made contact with the ball.
