We also tried an ultrasonic sensor, but it only reached about 14 feet. I don't know if it was the same one, though.

Beautiful machine making beautiful shots. The work you've done on the camera has really paid off. It seems like this will be a year where those who've developed a targeting system will really shine.

Congrats,
Nate

Looks like a great machine you guys have built. See you at the Utah Regional!

Re: Team 399: Eagle Robotics Presents: X-1
 

This looks good. Very well integrated. I also like the use of color. I too was having some trouble of figuring out if the color was blue or purple.

Re: Team 399: Eagle Robotics Presents: X-1
 

I can't wait to see it at the Utah Regional. Good luck this year.

I noticed in your description you said that different colored LEDs worked differently at different distances. Could you elaborate on that? Which ones worked best closer, farther, from an angle, etc?

Also, great job at the San Diego regional! You were unfortunately plagued by problems, so hopefully we'll see 399 pull a victory from Utah.

Thanks.

Re: Team 399: Eagle Robotics Presents: X-1
 

Thanks for the kind words.

From our testing, we've found these results:
Close range(< 5 feet): Red. Red isn't as intense as the rest of the colors so it doesn't wash out at closer ranges. However, it gets very dim very quickly as range increases.
Mid-Near range(4'<distance<16'): Green. Green works great at most useful ranges. However, at the close range, green washes out easily. At the far range, green starts to get a bit dimmer. Depending on your vision algorithm, this may or may not affect it.
Mid-Far Range(5'<distance< ~36'): Blue. Blue works really well at most ranges as it appears to remain a consistent shade of blue(to the camera) at most ranges. The only thing is that blue washes out at short ranges.
*"wash out" == appears to turn whiter

If I were to choose one color to use, I would pick green or blue. But I'd lean towards green as it fits our robot's colors better.

Another possible purpose for the ring light pre-match would be as a kind of a signal. Like have it default to white when there are no comms and switching to your preferred color upon gaining comms.

Thanks,
Jeremy
