Our biggest risk for the project going forward will be the main ball launch mechanism. We are confident in the design itself, but we are just not sure of exactly how far we will be able to launch the tennis ball. We are mitigating this risk by trying to overestimate the launch force, energy, power, and exit speed needed from the spinning wheels so that we will have some wiggle room, while also having backup plans in case it fails (spring load mechanism for guaranteed energy).
No changes in design nor schedule have been made thus far. Our main goal as a team for next week is to complete the design presentation for 9/28 and get a more complete Bill of Materials.
