There is a large rubber tyre about 1 3/4 inches diameter which comes with the Mindstorms stuff. Its a solid tyre and even though there's a lot of rubber, it's is fairly narrow and fits on the small sized yellow hubs. What I want to know is if there (...)

Are there any good ways to produce TEMPORARY markings on large areas of floor surface (mainly carpet, some linoleum) suitable for line following robots, etc.? Someone suggested masking tape, but that wouldn't be good for long term usage (leaves (...) (25 years ago, 18-Sep-00, to lugnet.robotics)

Eric, I've noticed that some of the TRUs around here (Cleveland, Ohio) still have both versions on their shelf, and the 1.0 has a big sticker on it saying that you can get the software upgrade free. The main difference is that 1.0 has the power (...) (25 years ago, 18-Sep-00, to lugnet.robotics, lugnet.market.shopping)

You can get 1.0 and 1.5 systems on ebay, but there is some risk and the prices are amazingly high (80-95% of retail). There is not that much difference between the 1.0 and 1.5 kits, and I recommend the latest release, because half of it is a (...) (25 years ago, 18-Sep-00, to lugnet.robotics, lugnet.market.shopping)

I think I can answer all of these. I'll make down what I'm not certain about, and my fellow list members can correct me as need be. 1. The only significant difference between the 1.0 and the 1.5 is the AC port, which the 1.0 has, but the 1.5 lacks. (...) (25 years ago, 18-Sep-00, to lugnet.robotics)

Hello, Everyone: I'm interested in purchasing an RCX, but from what I've read the 1.0 is a lot better than the 1.5 (and since they're still giving the upgrade kits free, what's the difference?). Can anyone explain the differences between the 1.0 and (...) (25 years ago, 17-Sep-00, to lugnet.robotics)

Remember that this holds most of the pneumatic stuff that does not move. If you only need one switch, then IMHO it is a very good switch/base. For more switches though, it could get a tad bulky. Andy (...) (25 years ago, 15-Sep-00, to lugnet.robotics)
