Kevin...
We have done BEST for three years here in Indianapolis and find it a great way to compete. We have been doing FIRST for 4 years. I, too, have been interested in using the VEX controller on a BEST robot.. I have talked to the powers that be about this also. The issue right now for BEST is that the motors that come with VEX are not strong enough (they are just servos after all..) to command a BEST robot. When we are able to interface BEST speed controllers with the VEX controller and utilize DC motors with the VEX system I think we will have a winner... after all the VEX controller and radio (even if you throw EVERYTHING else away from a kit...) costs less than the present radio and potential controller (DSP) for the BEST system...
I hope we can make it happen...
thanks

At any rate, it can certainly get very pricey. Especially for control systems, if you're using a full-size IFI RC there. The good thing about Vex is that you can get most of the stuff you need in one kit for $300, which is steep... until you look at a full size RC.
I will at this point mention the BEST robotics competition. For those that haven't heard of it, it runs on a fundamentally different model than FIRST. There are literally no entry fees to teams. A team puts down a deposit to cover kit items that must be returned like motors and controllers. All fundraising is done by the equivalents of regionals. Teams can only attend one, and must win to advance to the next level. Same 6 weeks time frame. The important difference is that teams are strictly limited to the materials in the kit of parts, and the robots are 2' x 2' x 2' and 24 lbs. And not programmable (yet). So it's a smaller program than FIRST in some ways, but capable of reaching schools that are very unlikely to have a FIRST team. As for the programming bit.... BEST is working on DSP based programmable controllers... and I'm working on BEST to look at shamelessly co-opting the VEX controllers.
The key point of the above is that there is no entry fee to a BEST team, though. FRC has an entry of $6000, FVC is $500 or so plus two Vex kits. Your mini-FRC competition would be around $500 or more for a new team. BEST is free. Or free, pending a $200 deposit. So, if there's a BEST hub in your area, you might consider pointing pointential FIRST teams at it before you terrify them with a $6000 entry fee.
EDIT: Oh yeah. BEST is in the fall. No worries about it interfering with build season. |
