Re: The advantage of holonomic drivetrains
Adding to what Ian said this happened with my team this year. We originally were using a tread drive sytem but our tread snapped. By the time we were on our 5th drivetrain and it was Thursday at the NYC regional we swapped for omni wheels in the front, knowing full well we wouldn't be able to get up the ramp.
Consequences of the omni wheels
We were able to turn which let us realign ourselves for shooting very quickly
We were able to be pushed very quickly while shooting
Instead of turning in very small degrees we made huge arcs, although our drivers got that under control
Our omni wheels actually broke
We were able to wreak havoc during the last 20 seconds of the game on the other side stopping from robots getting up the ramp knowing that we couldn't
We usually played backbot
In my opinion the good outweighed the bad, (we came in second), so it was a good tradeoff. If we had been primarily defensive and not played backbot, I'm not so sure the omni wheels would have been a good idea.
