Another Update

Today, we finalized our design and decided to change it slightly. We bought PVC pipes, elbows, and Tee pieces to construct our device, which functions like a catapult (tension from Bungee cords). We have the contraption built and put together, we just need a few finishing touches before we finish our first prototype. We need to figure out what we are going to be using for our release mechanism to let go of the pieces in motion (attached to Bungees). We might use a motor with a button connected, or a non-mechanical device that we have not decided on yet. We also need to find a way to attach the tennis ball to the pipe that will be launching it (tba). We will scan a sketch of the device ASAP, and will have another update next week, hopefully with our prototype finished.
