There's an older version of the black pegs that are even tighter. Too tight, in my opinion, so I've set the few that I have aside. You can easily tell the difference- look at a regular black peg. It has short lengthwise ridges on the ends about 2mm (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

(...) The black ones fit tightly into the holes in various Lego parts - the grey ones are a looser fit and spin freely. Use grey pegs to fit parts that will rotate relative to one another - use black ones otherwise. See this for more details about (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

(...) I believe that the patents on the basic brick/stud technology expired quite a few years ago - so you may just be able to do it. However, there are patents on lots of the *other* Lego components - so beware if you are planning more (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

HI, I am building a robot ant and using a light sensor to detect lines to follow. However, the algorithm I am using must not be deterministic; i.e. I need to do a sensor sweep and build a graph of the relative light levels at the left, front and (...)

Steve, Here's an "all gear" based solution (minus the chain I used from the drive shaft): (URL) not sure how much gear lash is in the design I came up with, but the thing runs very well (much better than I thought it would). It's been quite some (...) (23 years ago, 4-Apr-02, to lugnet.robotics)
