I think what he means is fabricate your own parts entirely and not use Tetrix
In this case there is a very strict limit on what you can use. If you go the the rules you can see you can us 36 inches of flat bar, square tubing, U/C channel, and L-channel. From my past experiences that is enough for a very simple robot, but not nearly enough for a robot that our team builds every year. Those are the only parts you can fabricate yourself. ( I know it becomes a bit expensive and kind of annoying, but you have to learn to deal with it or design for a cheaper robot) You can also modify any part by any means in the Tetrix kit (except for electronics). If the Tetrix kit wasn't mandatory teams like ours would probably be using many different means of assembly and FTC robots would vary as much as FRC in construction style and things like that. I know I modified sprockets this year for our first prototype of a catapult worked well but I still HAD to use a Tetrix sprocket instead of just machining it out of any old metal
