Tumbler Vs. Protobot

Creating an inventory for the tumbler was stressful. I myself made a few mistakes, and had to redo the part I did. The protobot with its more lax inventory rules made it much easier. Since we have already gotten the hang of it, it was much better. When building the tumbler, we had a few problems with the placement of some of the screws and we ended up having to take it apart to move a couple things. When we got around to the protobot though, we made sure we were much more accurate. The tumbler had a very stable, easy to repair/tighten structure. For some reason on the protobot, the pieces kept falling off, even though we tightened them as much as we could. The build is also more complex so it takes a bit longer to find what is broken/loose and repair it. I don't think there is much we could have done differently to make the bot better.
