Some ballpark numbers without thought to temperature and pressure. Approx lift for 1 Cu Ft helium = 1 Oz. RCX = 9 Oz. You might need two.... Motors = 2 Oz ea 4 (?) required Misc structure and balloon estimate 2 pounds? Total ( minimum ballpark) (...) (25 years ago, 26-Oct-00, to lugnet.robotics)

I was thinking of making a lego dirigible as part of an R&D project at my school. We came to the conclusion that we would need a baloon about the size of a small horse to get the neccesary equipment into the air. Though I still think that it would (...) (25 years ago, 26-Oct-00, to lugnet.robotics)

Hi, Bradley. As other people already told you, RIS is the most complete set. It is also the more expensive too. If you are looking for a cheaper and easier version, go for the Discovery set. The controller that comes with it, the Scout, has some (...) (25 years ago, 26-Oct-00, to lugnet.robotics, lugnet.loc.ca.on)

Hey! Anyone thought about making their rcx airborne? I figure we can do it with helium(lots and lots of helium) or with a hot air ballon. You could set up propellers and use a skid steering system. Yeah it would be reeeeeally difficult but i think (...) (25 years ago, 26-Oct-00, to lugnet.robotics)

Hi I think RDS is the best to you, except touch sensor, you also can use external light sensor in Scout, you can do most thing that RCX can do. I don't know if you can write NQC program as you are so young, you can refer page at (URL) there is a (...) (25 years ago, 26-Oct-00, to lugnet.robotics, lugnet.loc.ca.on)
