 | | Nxtcom error #89
|
|
I've been using the nxtcom utility to download NXC apps from my Mac. It was working fine just a few minutes ago, but all of a sudden (starting about 10 minutes ago) it's giving me a "NXT Error #89". I've searched the web and read the read-me, and (...) (17 years ago, 5-Mar-08, to lugnet.robotics.nxt)

(...) I will check into this when I get home this evening but I think your problem may be that BricxCC and NBC do not automatically download the .RIC files referenced in the program source code. Those must be downloaded manually, which you can (...) (17 years ago, 3-Mar-08, to lugnet.robotics.nxt, lugnet.robotics, FTX)

|

I'm just getting started with bricxcc (and winxp on my mac), so I'm hoping there's something painfully obvious I'm missing. I've compiled and run a few simple nbc and nxc programs (mostly from John's book), but invaders.nbc isn't working for me. I (...)

(...) I emailed Karen with the solution to her problem. This can trip you up if you aren't careful. Drawing values to the screen can confuse you if you draw over the top of an existing number without clearing the screen first. John Hansen (17 years ago, 29-Feb-08, to lugnet.robotics.nxt)

(...) Yep. But note that Philo was talking about *torque*, not force. A torque of 50 N•cm means that it could supply a force of 50 N with a lever arm of 1 cm, or a force of 500 N (more than 100 lbs) for a lever arm of 1 mm... but that would imply an (...)

Thank you for clarifying this, Brian. I was reading (URL) It stated that the NXT with "Stalled torque) up to 50 N.cm. 50N... it equates approximately 10lbs?!
