The best starting point I came up with is those inflatable beds, they take way to long to inflate normally and are to heavy as supplied but have other essential items. Or the other item is a good blower ( like out of a shop vac, normally only one stage) that can be powered by a kit motor (or two). Volume is the big issue as 0.2 lbs. of air pressure in a bag 36" x 36" x 13" will give you (36*36*.02=259Lbs) of lift. A thin tough ramp(s) attached to the sides of your bot that drop down with the bag under and a check valve (flap) to keep inflated after you lift your team mates bots. Rip stop sail material might be a good starting point for the air bag.
Not playing this year but still get to think about the game

the problem i can see with your design is after the match is over all power is shut off to all robots(you could try to put your air things on a separt circuit, but i don't know if it is allowed{CHECK THE RULES}
