I believe the weakest points are the axles. They twist and bend easily. At points where you have to transfer the largest forces, make sure you don't have long axle sections between the wheels. Keep the wheels next to each other if possible. If you (...) (25 years ago, 21-Sep-00, to lugnet.robotics)

A worm gear mounted against a 40t gear is, I believe, the 2-gear combination that provides the most torque. You may want to gear down the worm gear first, providing even more torque. In general, as speed decreases (assuming the decrease is caused by (...) (25 years ago, 21-Sep-00, to lugnet.robotics)

What is the strongest gear assebly? Using mostly RIS 1.5 pieces, but some extras, I need to design a gear box that has enough strength to lift the contraptions own weight. What is the strongest possible settup of gears that i could use to achieve (...) (25 years ago, 21-Sep-00, to lugnet.robotics)

I discovered, during the course of implementing a software interface to the Lego rotation sensors on another hardware platform altogether (not RCX) that there is a problem with the sensors themselves. They suffer from the well known "between states" (...) (25 years ago, 21-Sep-00, to lugnet.robotics)

(...) I have run into "count loss" using the rotation sensors also. I found that anything above 40RPM is somewhat problematic. I imagine the exact numbers depend upon the size of the program you are running and how it is designed. But no matter what (...) (25 years ago, 21-Sep-00, to lugnet.robotics)

Hi ! (...) I think that common sense might lead you to suspect a number like 60 rpm. That's one rev per second. You could watch it go round! The one I measured ran at ~380 rpm from the RCX and ~420 rpm from the 9 v battery pack with no load. JB (25 years ago, 21-Sep-00, to lugnet.robotics)
