Well, we had designed and cadded out an arm design about the second week of the build. We thought we had made it fairly simple, so we sent it off to be machined. It took us a while for the shop to actually get it, and they had to special order the metal to make it out of. Basically, we were supposed to get it on Wednesday, about 6 days before the ship date. Well, due to some problems we didn't get it, and we realized there was no way we could use that arm. We got really stressed out since we REALLY did not want to be a box on wheels. We thought for a couple hours, and came up with a different design. We had thought about the old design a lot(which in hindsight was a terrible design), and developed an entirely new system for picking up tetras. We went off to Lowe's and spent about $200 on generic pieces of metal. We started building our new, much more basic, design for the arm. That same night, a guy who worked the machine shop said we could go over there anytime we wanted, to get the arm pieces welded, etc. So we ended up really pulling together as a team, and designing, building, and modifying our arm design in about three days. It ended up working really well, and the simplicity of the design enabled us to keep an extremely low center of gravity. It was really incredible to watch our team work like we did, every single person on the team knew what we had to get done, and not a single person was left with nothing to do.
