| | one motor- four diffrent axles
|
|
I had a great idea. I'm not sure if anyone has done this before, but I have found a way to make one motor drive four (or more) axles, individually! The downside is that only one axle can be rotated at a time and in only one direction, and I'm having (...) (25 years ago, 26-Oct-00, to lugnet.robotics)

Hello, I designed just such a drive, using worm gears instead of ratchets. It does, unfortunately, take a tiny amout of time to shift between moving forward and spinning in place. Perhaps it will meet your needs anyway. The relevant images are steps (...) (25 years ago, 26-Oct-00, to lugnet.robotics)

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)

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.
