Hold up a minute. If your robot is 31" x 32", you will need to have some method of losing 3" or so for transport.

As far as omniwheels, they allow very easy sideways movement. You REALLY want traction wheels of some form, though omniwheels may be useful on the corners IFF the center wheel is not dropped.

Yeah, before you do anything else, you guys need to fix this or you'll be in for quite a surprise at competition.

Unless you are going to get really complicated, one dimension of your frame has to be under 28".

Actually, you needn't get overly complicated to have your frame length and width >28".

I'm assuming they'll want the height of their robot to be over 42" tall, which I guess is not totally necessary. Regardless, I don't see why they would be unable to trim three inches. Having to severely limit your robot's transport configuration height probably isn't worth it over something like this that could be remedied and would allow much mroe flexibility later in the build process. I mean, its only what, day 6?

Note: Please read ALL of the 2015 FRC rules before designing & building a Robot.

We want you to be able to play the game when arriving at the competitions, instead of having to help you rebuild it there (If we can all avoid it, OK?).

Please see The Rules, Robot Section; R3 & R4 for Transport Size & Wt. constraints. There are other rules that apply this year also (such as there is no on the field width X length constraint as long as it fits within the transport size...pits to the field, through doors, gates, etc....though there is a Max. height limit, both on, or off the field, and you must be able to setup and break down reasonably on the field within 1 minute or less, and everything must fit into that transport box size limitation for transport throughout the venue). So reading all the rules is very important...Stop building, start reading OK?
