 | | ARM Assembly Language Programming on NXT?
|
|
Hi, I just stumbled on this newsgroup/website while searching for kits for teaching Assembly Language programming to undergraduate students in Comp. Science in an interesting (interactive) manner. I'm primarily interested in the ARM instruction set. (...) (17 years ago, 8-Oct-07, to lugnet.robotics.nxt.nxthacking)

(...) So it sounds like a single loop should be no problem under most situations, since I'm not sure I've heard of anyone running three motors on a single train (there's the same issue with how much amperage a power regulator can push). (...) It (...) (17 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

(...) Stalled, the train motor pulls 950 mA, while the stall current of the NXT motor is a whopping 2 Amps. So a single NXT motor output should easily handle a twin-engine train loaded to the point where it stalls the engine(s)... there's the matter (...)

(...) Fair enough, but clearly the idea has sparked some interest, so I'm sure I'll see it get put into use at some point. (...) The ports may be able to pour out power, as you say, but I'd say it's equally well established that large trains with (...) (17 years ago, 7-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

(...) As Ross mentioned, I was focused more on the "future" of trains, and if it's going to be done in LEGO, it looks like it will be done without conductive track. (...) Absolutely, but you could do better. Run a single loop off a single output, (...) (17 years ago, 6-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

(...) Oh, for shame, Brian. Letting me think up an option that you passed right over (and a really cool one at that). With the legacy converter cables, you could power the _track_ with an NXT. Hook the track up as if it was a motor, using the (...) (17 years ago, 6-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

(...) Not exactly, that I know of, *yet*... The biggest problem in running a train would be hiding the NXT - I saw only one good solution to hiding the RCX in a boxcar, and the NXT is bigger, as are the motors. You could use an old motor (or even a (...) (17 years ago, 6-Oct-07, to lugnet.lego, lugnet.robotics.nxt)
