Re: pic: Team 25 IR Goggles
how does that work its it just a filter or is it like a sensor?

Re: pic: Team 25 IR Goggles
Kind of a dumb question, but what is the point of them?

The point of the IR Goggles is to be able to see the Infrared light being emitted from the remotes on the field. Therefore we can use it to minimize transmission interference and ensure proper communication with the IR board. |
Re: pic: Team 25 IR Goggles
I recall a rule prohibiting tinted safety glasses. Also, the "communication system" of the RoboCoach is specified to be "handheld", which may pose another issue. Pretty cool looking though.

Re: pic: Team 25 IR Goggles
Wow!
I've gotten the chance to see them work and its absolutely nuts, you can see beams of light, like light sabers in blast. This will enable 25 to determine transmission pulse structure and maximize their IR performance. It is going to be interesting to see them in action. |
Re: pic: Team 25 IR Goggles
That is really cool, I never would have thought of that. Nice thought!

Re: pic: Team 25 IR Goggles
how much did they cost, and where did you get them from? (if i may ask)

Re: pic: Team 25 IR Goggles
So, we've been getting lots of IMs and emails about how you can't see IR indoors. Well, this video was taken indoors--decide for yourself. :)

Uhh... guys, I don't mean to rain on your parade, but isn't this kinda a direct violation of <T22>?

Re: pic: Team 25 IR Goggles
wow that is cool
...now I want to go make a pair just to see the world (except the sun) in IR-Vision |
Re: pic: Team 25 IR Goggles
These are pretty cool, but I don't see an advantage in the matches.
Camera sensors with proper IR filters can see IR and they make impressive videos. However, it is impossible to make a video of what the human eye actually perceives. You will not see a beam of light from the LED. They are low power and disperse fairly quickly. You may see that someone has sent an IR command if you are in line-of-sight of the remote. If one was curious of the science behind this field of optics, go for it. To the rest thinking it will be allowed in the matches, save your money. Spend your time and resources on improving your robot performance. |

<T22> disallows devices which give the robocoach a competitive advantage. By allowing your robocoach to see the IR beam through these nifty glasses, and align precisely with your IR receiver, and avoid interference, aren't you allowing him/her a competitive advantage, as the ability to see the actual beams is not shared by all robocoaches? Additionally, what do you mean by the drive team giving the robocoach a competitive advantage? |
Re: pic: Team 25 IR Goggles
I'm still not too clear on how these work. I understand that the red and blue filters allow only the IR light to be passed through, but why does that matter if the human eye can't see IR in the first place? It makes sense that it would work with a camera because of how digital cameras detect light, but if the human eye can't see it then how does only exposing the eye to IR help at all?

I've been fiddling with this, too. How do you guys make them? They look like video goggles. |

At team 25 we always see the world with rose colored glasses

Try it out with your camera phone and a TV remote.... same effect. Its how I check to see if the batteries are still good on my TV remote (depending upon the TV remote being functional of course). Free IR Hack: Put your camera phone in picture mode and watch the screen. |

Where can i find said goggles?

May I divert your attention to the Stuntmaster IR Headtracking project? :rolleyes: |
Re: pic: Team 25 IR Goggles
Just open up an old digital camera, find the CCD chip, remove the small glass infrared filter and replace it with a couple pieces of exposed 35mm negatives (found on the end of every strip of negatives from back in the analogue days).
Put it all back together and you have a perfect infrared camera that blocks all visible light, and allows you to use a remote control as a flashlight. Pictures coming soon. |
