Last night, aside from difficulties focusing the camera, our camera's images looked pretty good after turning on white balance for a couple frames. However, it seemed that when we used the tracking function, it seemed to lock onto whatever was in the center of the camera's field of vision to determine what color to track. For example, I held up the backup battery in front of the camera, set it to track blue, and the camera showed my hand as being more blue than the backup battery case. Any ideas on why that happened?

We have the CMUcam2 software on a PI/Celeron 500mhz laptopw/ win98SE, and the only thing that doesn't work is the grab frame because the sofware was witten for 1024x768 and the laptop only supports 800x600. Did you make sure your serial port was configured correctly in all cases?

Yes, the serial port is correct, but the screen resolution may be a clue. I wish the CMU guys would realize that not everyone has a big screen. I have the same limitation on my laptop as well. Makes me wonder what we're going to do when we get to the regional.

Thanks for the info.

The java program seems to have an unbeleiveably annoying tendency to freeze. It has frozen on both my computers at home, in addition to two computers at school. We were going to run it on our awesome alienware laptop, but the usb transfer stick went nuts on us and our network is so screwed up we didnt even bother trying to use that.

Have you been able to find something about the built in PID that was mentioned and the "walk, turn" commands that were also mentioned?

I'm looking for info on those like crazy, but i can't seem to find anything


I haven't opened the kit yet, we didn't receive it here in Brazil, it’ll only come on Monday.

Thanks, sorry for the Bad English

If you look in command.h, you'll find the list of commands and their parameters. Then look in robot.c and you'll see how the commands are executed.
