wow that is cool

...now I want to go make a pair just to see the world (except the sun) in IR-Vision

It turns out that you can see the world in IR by (carefully) removing the hot mirror and putting the Congo Blue and Primary Red filters in their place inside a digital camera. It's pretty awesome.

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.

I won't deny however, it is super cool.

This rule is intended for the drive teams giving the robotcoach a competitive advantage. It says nothing about remotes.

You're right. It does say nothing about remotes. But if I understand correctly (and please correct me if I'm wrong), you plan on having your robocoach wear these nifty glasses that let them see IR beams.

<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?

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?

The naked eye CAN see IR. It's just that it's so horribly washed out by "visible light" that we never notice it. Filter out typical "visible light", and what do you get? IR.

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

Can you quote the Q&A? I searched and have read through all of them, and cant seem to find anything regarding the Robocoach wearing IR glasses.

I only said headmounted. I said nothing about IR vision.

I don't think so. The eye can barely pick up anything over 700nm (ie essentially cannot see), and IR starts at 750nm. If we could see IR, then many IR based nightvision systems would be pretty much flashlights, and chimneys would glow at night.

This first generation headset proved to be clumsier, heavier, and less effective than the previously posted modified one.

That is the camera viewing the IR source, not a naked eye.

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.
