Re: pic: Team 25 IR Goggles

how does that work its it just a filter or is it like a sensor?

Both. We wanted to see the interference and have true line of site driving.

Kind of a dumb question, but what is the point of them?

First of all, the only dumb question is the one you don't ask!

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.

Headmounted has been declared OK by Q&A. The tint might be an issue, but certain tints are legal.

how much did they cost, and where did you get them from? (if i may ask)

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.

Re: pic: Team 25 IR Goggles

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.

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.

Re: pic: Team 25 IR Goggles

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

19-01-2008 01:04

Ian Curtis

Re: pic: Team 25 IR Goggles

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?

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?

Re: pic: Team 25 IR Goggles

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.

Re: pic: Team 25 IR Goggles

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.

Re: pic: Team 25 IR Goggles

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).

Put your camera phone in picture mode and watch the screen.

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.

Re: pic: Team 25 IR Goggles

I tried to do this with a legacy camera but i couldn't manage to take the camera apart without destroying some circutry. i found some DIY page on the internet witch discribed exactly that. If you do that Please pass it on. There are a few gizmo's im working on that would benefit from your knowledge
