(...) Hi Mike, Unfortunately there is no possibility under Robolab 2.5 that the RCX might itself access the data collected in the log. Robolab 2.5 is based on LEGO-firmware 2.0, which has many new features, but not this one. If you want to do your (...) (23 years ago, 4-Apr-02, to lugnet.robotics.rcx.robolab)

I've uploaded a simple detent mechanism which can be used to stop shafts creeping round when they're not supposed to. The only drawback is it can get rather noisy :) (URL) black shape at the top is supposed to represent an official Lego rubber band. (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

Steve, If the precision is due to the axe slipping while not being driven, you could consider using a pully off a micro-motor. It has a friction slip mechanism at one end, and an axle hole at the other. You could use the axle hole to stablize the (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

Nice work! Could you potentially use a ratchet mechanism or maybe a step motor set up (with a rubber band) to help with the "coating" problem? Jona ----- Original Message ----- From: "Steve Baker" <sjbaker1@airmail.net> To: "Kevin L. Clague" (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

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 (...)
