I don't know much about mechanics or walkers, but what about a gyro device that's more stable than a rotational sensor. Surely someone out there would know how to use one of these to "balance" a walker. Of course this means powering the gyro to spin (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

The large weight waiting to drop would be a bunch of (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

(...) I don't have the time to work on this, but I see a relatively simple way to do this that might work well. Build a column to stack all 3 cans into. Place 3 "spikes" roughly dead center at each can, the RCX powers a bar that moves the spikes in (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

Hi There, Hmm, you found the loophole! Okay, the rules have been changed to indicate that all cans must be crushed at least 50%. This should prevent the instant win, but still keep the formula as it was. The updated formula is a good one, but since (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

Sorry if this one has been suggested: (URL) have seen two others, but searches came up empty and didn't someone post a brick sorter that read in a sequence of 1x2 tiles to produce an "order" to be "picked" from hoppers of different colour? Couldn't (...) (24 years ago, 13-Feb-01, to lugnet.robotics, lugnet.general)

| | Oops! Darn diode/fuse
|

So while trying to modify my brick to accept 9v from an AC adapter, I managed to blow the SMT diode/fuse. Anyone know the rating (or part #) of the fuse/diode so I can replace it? While I'm at it, anyone know what voltage/mA the RCX can take as (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

(...) I'd better submit my model (which is one 2x1 plate and nothing else) it scores 2 points...and may yet win if nobody succeeds in crushing a can and everyone needs more than an RIS set to attempt it! (24 years ago, 13-Feb-01, to lugnet.robotics)

I have added a "Block & Tackle" based LEGO device to my site at (URL) Check it out. Block & Tackle is a formal mechanism, as much as a wedge or lever or gear. It has some amazing benefits. But it's hard to work it into a design and some of its (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

Doesn't a machine that does nothing score perfectly? If so, my entry is an RCX sitting next to three cans. It finishes the instant it starts. You have a formula time * height * bonus = score, with small being better. So a robot that does no crushing (...) (24 years ago, 13-Feb-01, to lugnet.robotics)
