If you haven't checked out Jin Sato's "Lego Mindstorms The Masters Technique", then I urge you to do so. Chapter 3 (pp. 19-50) are devoted to gears, gear ratios, and ways to make gear blocks. The book took forever to be released, but well worth the (...) (23 years ago, 20-Apr-02, to lugnet.robotics)

| | Getting Gear Ratios Right
|
|
Considering that gear ratio is such a fundamental concept, it's disturbing that several authors of Mindstorms books have got it confused. A good explanation is to be found on page 65 of Ben Erwin's "Creative Projects with LEGO Mindstorms". The best (...) (23 years ago, 20-Apr-02, to lugnet.robotics, lugnet.technic)

You can still switch back and forth between legOS and NQC if you find the joystick control helpful. Another suggestion is to write a legOS program that runs all axis at intervals...if you just need it for testing. A final suggestion is to use the (...)
