Greetings all, Dave here. I'm making a quick post to remove some of the confusion I may have inflicted on the community. I am assisting this year with gbc, not coordinating. Steve, Bryan, Brian, John, et. al. will still lead the pack like last year. (...) (19 years ago, 8-Jul-06, to lugnet.robotics)

| | RE: RCX vs NXT for FIRST?
|
|
As a coach of 5 years experience it depends on what your focus is...if it is educational - stick with RCX as the NXT takes away a lot of problem solving and thus learning on gear ratio's and motor strength. If it is simply to win - use the NXT. Our (...) (19 years ago, 8-Jul-06, to lugnet.robotics)

(...) By "block" I mean a NXT-G code block as dropped from a pallet. Yep, you would think that these things would compile down to a single bytecode (or a few bytecode sequences), but they don't. There is an awful lot going on under the hood, and (...) (19 years ago, 8-Jul-06, to lugnet.robotics)

(...) By "Block" you mean a simple operation like and add or a multiply or turning on a motor or reading a sensor? These 'blocks' ought to be turned into little interpreted byte-code segments - it's hard to imagine how a block could possibly take up (...) (19 years ago, 8-Jul-06, to lugnet.robotics)

Thank's for setting up that list. Is there a way to tell if an adapter has been tried and doesn't work, or just hasn't been tried? Note that I did get he Kensington to work on XP and OS X as you can see from my later post. (19 years ago, 7-Jul-06, to lugnet.robotics)
