But did the practice bot weigh more than 30 lbs? If so, I don't see how this could ever be okay. Especially since parts were used from it on the competition robot.

I'm guessing every part on the practice robot was assembled, so none of it was COTS.

I don't even think it matters that you modified the part that was swapped over. If that works, why can't we all bring second robots, grab parts off and drill some holes to modify them, then slap them on the robot and say we "manufactured" them in the pits?
