Important question regarding starting position of balls in the BOT

[Nimmy]

hey guys, my build team just posed a tricky question, which im almost 100% sure the answer is positive

the question is wether or not balls are allowed at the start of the match (we are speaking of the 10 autonemous balls) to be under pressure, what I mean is

we have a conveyer belt to push the balls up our bot from the floor, the coveyer belt puts the balls under a very strong amount of pressure so they will go up easily, are we allowed to put the balls in that stress-position before the start of match?

also on the same question, can we put balls on the floor beneath our bot?
thank you very much.
