Making a Frisbee Launcher (and failing)

This time around, I tried to build a frisbee launcher, which I had hoped to expand into a fully-featured frisbee launching robot. Spoiler: I failed. I also spent some time chastising Mark Rober for his design process, which I probably should have followed more closely. Oh well.
If you're interested in building machines using motors, you can probably still find some valuable information here. Just remember that motor are scary.
