It's not allowed. Not only can your mini bot not extend outside 12" by 12" by 12", but your big robot now cannot assist the mini-bot up the pole in any way. It must go up by its own power. Furthermore, a mini-bot now can't store energy in flywheels, surgical tubing, etc. All of this based on the week 1 update found here.
