to control its own movement through the air. I would guess one could be built
small enough to test indoors, say in a high school gym.

I dunno.

Some coworkers and I were investigating home-made helium blimps for a homegrown
robotic dirigible race competition, and the amount of helium required to hold
up a few ounces was staggering.

Either my calculations are wrong, or you have a different concept of what is a "staggering" amount of helium. Here are my calculations: Each gram-mole of gas at STP [1] takes up 22.41 liters (cubic decimeters) of space. The weight of a mole of air (...) (25 years ago, 9-Nov-99, to lugnet.robotics)
