(...) Seriously? OK, whew! Then I *was* just being paranoid. I'll cross my fingers then and hope that 1.5 also has this property. (...) Amazing. Excellent. All is well with 1.0 then! (Whew!) --Todd (25 years ago, 30-Jul-99, to lugnet.robotics)

It's only a guess but perhaps they picked that sort of ratio to make sure that it would be easier for small kids to play with them - having a 1-1 ratio might be more confusing for kiddies who are just about getting old enough to work out which way (...) (25 years ago, 29-Jul-99, to lugnet.general)

Okay, I'll bite -- how do you get 7/6 to be anywhere close to SQRT(3)? 7/6 is 1.167, and SQRT(3) is 1.732. Is there an additional 2:3 ratio hidden inside the "8880 transmission"? Also, I'm having a little trouble figuring out how the transmission (...) (25 years ago, 29-Jul-99, to lugnet.build)

The MPEG section is pretty cool. A wide variety of solutions to the same challenge. Robots with touch sensors, light sensors, robots with no sensors at all. "Kenny" and "Michel Dowling" are impressive no-sensor versions - they both drive a nice, (...) (25 years ago, 29-Jul-99, to lugnet.robotics)

(...) That is true except for removing the firmware by removing the batteries.

Why is the 5-to-6 ratio supposed to be such a great thing? I still think that a 5-to-5 or 6-to-6 ratio (better known as 1-to-1) would have been much better. It would, for example, make it much easier to build things at right angles to other things (...) (25 years ago, 29-Jul-99, to lugnet.general)

But from that, doesn't it follow that this statment would be true?-- It is possible to write replacement firmware which, when downloaded and executed, still allows new application code but prevents the downloading of (...)

It would make messages like this an awful lot more understandable if you could try supplying a few set names with all those numbers. Or do you expect all your readers to spend 10 minutes looking up numbers on the lugnet database before they'll have (...) (25 years ago, 29-Jul-99, to lugnet.loc.uk)
