This week was fun for us because it was a chance to get some hands-on assembly and analysis done with the motor lab. It took longer than expected, but we had a good time doing it and learned some things from it as well. We found it rewarding to finally have an assembled part sitting in front of us that is going to be part of our machine.

This week will be stressful for us, as well as all of the other groups I'm sure, because we will have to get into the shop and do some manufacturing. We spent some time this week tweaking some of our pieces and finalizing the drawings so that we will be ready to get our work done in the shop. We are very excited to get in and start machining some parts, and to see them come together into a working machine!

I'm including some of the diagrams we used in the analysis of our machine. We modeled our arm as a simple cantilevered beam, with a load equaling the weight of all of the balls in the arena acting at the end.
