I would check with your local FTC director and with FTC at FIRST.
I doubt if you could purchase the same kit the FTC teams purchase. (Yes they PURCHASE their KOP)
Here is something that is almost identical and might be what you are looking for:

There are other options (without the lego set)

You could also get the metal only kit without the motors...or purchase specific parts like this one:
battery pack (legal for FRC)

motor (FRC legal I think)
http://www.legoeducation.us/store/de...&c=0&t=0& l=0
etc on this site...
Unfortunately the big kits mentioned above are temporarily out of stock... the battery and motor are instock... so depending on just how much you need... you could get the bare minimum which would be a motor and battery and then work from there...
If you want to micro control this package you will need some other stuff. battery wiring harness and the speed controller and a lego NXT brick...
My suggestion is that you find a local FTC team to work with... if you have any
Good luck
