(...) Good idea, and I should have added that to the list. But a high-thrust LEGO air propeller or fan seems to be even tougher to make than a water propeller. There's been a lot of discussion in the past about LEGO hovercraft, but it's rather hard (...) (17 years ago, 14-Sep-07, to lugnet.robotics)

(...) I consider the ZNAP flex axles "not good enough" to be put to good use. Another useful item from the ZNAP collection, however, are the wheels. They have a turbine-like shape and from what I remember from past testing in the kitchen sink, they (...) (17 years ago, 13-Sep-07, to lugnet.robotics)

(...) Those are a good all-LEGO solution... but they tend to splash. A lot. This isn't fatal, but means either "splash shielding" the electronics (which requires more weight), or making the entire robot bigger (so the splashing wheels aren't close (...) (17 years ago, 13-Sep-07, to lugnet.robotics)

(...) I'd love to see more people try this. It's a little bit risky (usually, when my programming skills fail the robot doesn't end up stranding in the middle of a lake... or worse, on the bottom), but it brings up a whole new range of problems and (...)

(...) You know, what I like most with your project is that is such a refreshing, new challenge, which - as you pointed out- surprisingly few people though of yet. So, this might become a completely exciting NXT robot section. I think it was in 2005 (...) (17 years ago, 13-Sep-07, to lugnet.robotics)

(...) Actually, I haven't thought of that - at least partially because I've never had those axles. But I would think that a vertical axle driving meshed crown gears to drive the horizontal propellor axle, or even an inclined axle that is turned (...) (17 years ago, 13-Sep-07, to lugnet.robotics)
