| | 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)

I am an AFOL because it is a very easy to use medium in which to construct and evolve mechanical devices - such as robotic platforms.

Here is a program letting you play with InfraRed Ranging using the standard Light Sensor and the built in IR Communications Port. You can play around with the THRESHOLD value with 2 light sensors and see what kind of range and consistency you get at (...) (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)

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)
