... (...) Hi John, I just tried to load it and just tested the "Try-me" light sensor. It worked fine. Not so much help, but I can try some more another day. Good work. Rasmus (...) (18 years ago, 19-Mar-07, to lugnet.robotics.nxt.nxthacking, lugnet.robotics, lugnet.robotics.nxt)

| | Last call for my New York City NXT Meet-Up
|
|
I have the LEGO MINDSTORMS NXT ROBOTICS SET and since I'm so "into it", my father and I were thinking we could start up a Lego MindStorms NXT Meet up group/club in New York City where we could meet once a month (or every other month), build, (...) (18 years ago, 18-Mar-07, to lugnet.robotics.nxt)

| | Detecting stall and slip conditions in NXT-G
|
|
I published a new "sensor" NXT-G Block that monitors that actual power sent to the NXT servos. This is useful to detected both stall conditions as well as the move challenging slip conditions. Full description and download are here: (URL) Ziv (...) (18 years ago, 18-Mar-07, to lugnet.robotics.nxt)

(...) It actually was not a very big deal. I was familiar with the firmware source code since I had looked at it quite a bit since it was released, trying to figure out how to get it to compile with GCC. All the RIC bug fixes were things I figured (...) (18 years ago, 17-Mar-07, to lugnet.robotics.nxt.nxthacking, lugnet.robotics, lugnet.robotics.nxt)

| | Enhanced standard NXT firmware
|
|
Over the past couple days I have used the IAR Embedded Workbench to implement some enhancements and bug fixes for the standard NXT firmware. The bug fixes are as follows: 1. RIC drawing code incorrectly checked the size of the OP_LINE structure for (...) (18 years ago, 16-Mar-07, to lugnet.robotics.nxt.nxthacking, lugnet.robotics, lugnet.robotics.nxt)

(...) Unfortunately the ultrasonic sensor can't even detect the red and blue balls when stationary. (Unless you're REAL close: within an inch or two.) Their surface doesn't reflect much sound (perhaps something to do with the index of refraction), (...) (18 years ago, 15-Mar-07, to lugnet.events.brickworld, lugnet.robotics.nxt)

(...) Yes, that could work. We just need someone to design a "standard" pitching machine that can toss balls a foot or two. Then, we need a "regulation" bat size. We could do the whole base-ball, but I doubt very many people could field a whole (...) (18 years ago, 15-Mar-07, to lugnet.events.brickworld, lugnet.robotics.nxt)

We could use those red and blue spheres that come with the nxt... Would ultrasonic sensor work for detecting the (...) (18 years ago, 15-Mar-07, to lugnet.events.brickworld, lugnet.robotics.nxt)
