Worm gears are terribly inefficient, that's correct. We used them on our robot, and struggled getting enough power to push and climb the ramp. I don't think we'll be using them next year as they didn't work out as much of an asset this year. But at least we can say we tried! And as far as backdrive, you could still push our robot relativly easily even with the wormgears, they did have some give to them, which kind of defeated the purpose of having them on there in the first place.
