 | | EggArt - a 4-colour Easter egg painting robot
|
|
Just in the nick of time, the day before Easter, I completed building a 4-colour NXT Easter egg painting robot. I started building it several months ago, when I thought I'd have plenty of time before Easter. Of course, at about the 85% complete (...)

| | RE: Using NXT Port 4 EIA-485
|
|
I've looked at implementing an interface for RobotC, but I've always struggled with why bother since there are no applications that connect to it. I wish LEGO had implemented an option to provide a logic level "RS-232" UART on port four. Yes, I (...) (18 years ago, 8-Apr-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)

(...) As far as I know, there isn't any support for this interface in either the standard firmware or any of the other third party firmware implementations. The interface runs at 921,600 bps so it will be fast enough to be really useful. I am hoping (...) (18 years ago, 8-Apr-07, to lugnet.robotics.nxt)

(...) It may work, but it will be very slow. The NXT runs the i2c ports at only 9600kb/s, so the data will trickle to the NXT very slowly. (...) I think that the answer is yes. (...) (18 years ago, 8-Apr-07, to lugnet.robotics.nxt)

|

(...) Thx for the comments. The design as it stands right now would not allow the sorter unit to rotate all the way around - not a bad idea though. I wanted to challenge myself with the angle idea on the sorter itself (2 rows of cups). With larger (...) (18 years ago, 8-Apr-07, to lugnet.robotics.nxt, FTX)

|

Hi, is there currently any software-support (pbLua, NXT-G, NXJ) for NXT Port4 highspeed serial communication (EIA-485) ? This port can be used for connecting some new hardware (camera, SD-Card-storage) to the NXT... Thanks for more informations Bye (...) (18 years ago, 7-Apr-07, to lugnet.robotics.nxt)

|

Hi, current version of pbLua (Beta-3) works very well for me :D But now I have some more wishes for the next versions: 1. Filesystem (storing chunks and data at NXT) 2. Console via BT (I have autonomous robots with cable) 3. Audio e.g (...) (18 years ago, 7-Apr-07, to lugnet.robotics.nxt)

| | NXT external storage
|

Hi, what are you thinking about extending the NXT with an external storage for more sounds or karthographic data ? A simple hardware interface NXT==>I2C==>IOPort==>SD-Card is not the problem, but how can this supported by operating system (e.g (...) (18 years ago, 7-Apr-07, to lugnet.robotics.nxt)

(...) Cool stuff, and a very elegant design. I was wondering if there is a reason you don't have cups all the way around the sorter? Have you tried to put the color sensor inside a housing to cut down on ambient light? And the real question the (...) (18 years ago, 7-Apr-07, to lugnet.robotics.nxt, FTX)

What better idea to come up with to test the HiTechnic colour sensor then to build a LEGO brick sorter. So, that’s what I did. After quickly learning that the sensor does not read colour from a distance (in my excitement I forgot to read the (...) (18 years ago, 7-Apr-07, to lugnet.robotics.nxt)
