Ahem...

Due to the number of people who are trying to exploit the weight advantages... :P

House robots can weigh up to 500kg, but NO weight bonuses for shufflers, walkers or any other motivation than wheels.

In the house robot rebellion, you may enter a bot that is within the antweight and superheavyweight range (moot if its already filled, but... :P), meaning 150g-150kg, nothing under, nothing over. :P

Understood? :P
