(...) You can push the gearing still higher - 1:1 isn't the upper limit. But the trick with gearing is to match the gearing to the torque that the motor provides - and to use as few stages of gearing as possible. If 1:1 gearing is optimal - then (...) (19 years ago, 25-Mar-07, to lugnet.robotics)

First, I'm a beginner. So it will be very easy question for you guys. I have to make a lego robot with RCX model as fast as it possible. I just can use two motors and 4 wheels. It means I can use only a 'driving base'. I made gear ratio for 1:1, and (...) (19 years ago, 25-Mar-07, to lugnet.robotics)

(...) Thanks for the heads up, this is wonderful to see. We primarily came up with the GBC idea for exactly one of the reasons you mention in the PDF - we wanted a collaborative, not competitive, LEGO event for groups, clubs, and kids. It has (...)

At the recent LEGO Engineering Conference 2007 in Singapore, (URL) showed how kids using ROBOLAB 2.9 could learn about proportional control and apply it to their robots like making a model car go a precise distance and a proportional control line (...)

Alexander, Thanks for the differential/pole-reverser idea. Based on your description, I was able to get a prototype running very rapidly! I'm still seeking a clean more mechanical version, but this certainly will work for now. Along the lines of a (...) (19 years ago, 23-Mar-07, to lugnet.technic, lugnet.robotics)

I have implemented OP_WAIT and a variant of OP_WAIT which takes a variable rather than an immediate numeric value (which in nbc is called "waitv"). I also modified NBC to accept a command line switch that tells it whether the firmware supports waits (...) (19 years ago, 22-Mar-07, to lugnet.robotics.nxt.nxthacking)
