Re: TEAM 1699 BUILD CONCEPT!

Team 166 tried building identical robots last year. While it didn't work out exactly as we had planned, it still provided us with a good chance to make the second (competition) robot, get a little bit of driving practice, and a lot of spares.

Hubs were welded onto a shaft in the elbow, so if the shaft broke that's it. Of course, while practicing before River Rage, the shaft broke. Fortunately we took the effort 6 months before to build an identical robot and had an entire new arm to put in place of the broken one.

It would be better to make identical robots with identical materials, not one out of plywood and one out of aluminum. This is for spare part purposes and so driving the robots feel the same.

Also, make sure your budget can accomodate both robots. We decided to use AM mecanum wheels with a healthy amount of Banebots transmissions with encoders mounted on them. We pretty much ran out of money.

There are a lot of risks to take like having enough money, time alotted, etc. but if you do it right, you can end up with a machine that the drivers can use to practice and the programmers can use for autonomous. In a game like last year's where driver skill is incredibly important, this concept can be huge.
