@andyblackfox13 you can go over the 18 in x 18 in x 18 in cube after you leave the starting position.
I just want to clarify that the original question asked if you have to wait to get out of the starting “box/platform”, which I’m assuming means starting tile. No, you do not have to leave the tile, as soon as the match starts you are allowed to expand.
yes.
The only size constraints are before the match. Your robot, should, in isolation, be smaller than 18x18x18 inches before the clock starts. After that, however, you could be as big or small as you need
