Post Mindsensors NXTCam v2
Hey everyone -

Here's a little something we've been working on: http://www.education.rec.ri.cmu.edu/promo/robot_c/media/NXTCam/NXTCam.html

Would anyone out there be interested in seeing more materials/support around the NXTCam?

Here's the sample programs too: http://www.education.rec.ri.cmu.edu/downloads/lego/resources/robotc/programs.zip

hi,
actually yes - but actually : I'm doubtful, too.

I got 2 of the nxtCam1's,
the 1st didn't recognize any colors,
Image
and the 2nd even hasn't been recognized by Windows as a USB device at all.
It obviously had been hardware failures and malfunctions.

The shipping costs to Germany have been enormous,
and I got a rediculous refund for my returns.

I would be stupid if I risked such a flop and such a loss again.

But I have an idea - I make you and Mindsensors an offer:
If you sent me 1 for free, I'll test it and maybe write you a good review if it really worked.

I guess they've made some pretty significant improvements since then. I've been using the NXTCam v2, and it installed on my Windows XP machine just fine (with the provided drivers).

The operation was a little quirky at times, but overall (as you can see in the video) it's performance was great. If/when we get around to doing a piece of support software around it, I'll be sure to consider your offer. :)

This is great! Im going to take a peak at your source files B-).

I think camera support would be wonderful, it is really powerful in controlled environments. I made a fire fighting robot to find and extinguish a flame using the camera, I think should be something to spend time on.

ok, maybe, my experiences were very bad.

Send me 1 for free, and maybe I'll change my mind... :poke:

I have ordered one of those NXTcam2s. Friend of mine is bringing it over from the US when he comes back from his business trip. I should have it in a few weeks or so. I will let you know how it goes :)

I'd contact Mindsensors and request an upgrade. I know they're upgrading the version 1 cams to version 2 now... we had one done here for ROBOTC testing.

Jesse,

Thanks for the source code! I just got my NXTcam2 so I am looking forward to tinkering with it. I would definately love to see more materials supporting this sensor!

Regards,
Xander

I found your video very useful for getting the NXTCam to follow the ball. But Im still having trouble with my program, I think its because we are using different lib the one the video uses #include "RAnxtCamLib.c" while I use #include "nxtcamlib.c" so my question is do I have to get that library (the RAnxtCamlib) or can I use my current one? and if possible could i see some more videos? maybe the ones that lead up to the one you just posted?

Thanks a lot,

Rookie

I am trying to test your program that recognizes different colored objects but I am using a V1 camera. I am getting a compilation error because of the #include "RAnxtCamLib.c" while I use #include "nxtcamlib.c"
Do I need to get that library (the RAnxtCamlib) or can I use the nxtcamlib.c

Thanks,
Nivea

The library comes with the programs.zip file.
