RACK & ROLL Reaction

[Bongle]

The actual rule states

ROBOTS in HOME ZONE - ROBOTS score bonus points at the end of the match if they are
entirely in their HOME ZONE, not in contact with any element of the field (carpet, alliance
station, goal etc.) and the lowest point of the ROBOT is higher than 4 inches and/or 10
inches above the carpeted field surface.

So your robot simply CANNOT be touching carpet. Not just 'wheels off carpet', but 'everything off carpet'. This means that jokes about fans notwithstanding, the most bonus you can get is 60 points since at least one robot must be on carpet in order to lift two others.

I've thought about it, and it seems that a crane of some sort built on your manipulator (and a semi-standard hook on the to-be-lifted bot) is probably the most viable lifting method. A more universal method where you jack up an alliance robot would probably be more unweildy.
