@jsrarne1 Hi Jay What is your thought about using a modulated ir signal (type of signal from a TV remote, for example. The signal generated could be a number) instead of the glyph? The signal would be a focused beam, not open, which would flood the room. (Requires maybe Arduino to decode then sent to the ezb) Maybe it would work?

I didn't get to Gitub yet, but will when work slows down.

I think you are correct that you would need to decode with Arduino. I had discussed something similar couple of years ago to have some way for the bot to automatically follow me and DJ at the time indicated the camera/EZ-B/WiFi would not be a good solution for reading the signal because it would potentially miss the pattern of flashes that would make the beacon unique.

But using something that can read IR and then just populate a variable that ARC could read through any number of different integration methods that already exist might be a good solution for this.

Hi Alan, Yeah, I was thinking about using the concept of the line follow idea. The receive would read the number a camera would see the beam? I don't think the pulsing of the beam would be an issue. Maybe later tonight I will see if an ezb camera would see the beam from a TV remote. A stationary sender would repeat enough times to allow the camera enough time to pick up the signal. Thanks for the reply.

I finally had a chance to confirm the ez robot camera sees the ir signal from my TV remote. I was only able to "see" dimly, about 10 feet. I will be looking around for a toy or try to find some lenses to make a "beam" which I will try to use as a target to use for tracking and also decode as a descripted signal. I am still busy but hope to get to test soon.

Is anyone aware of any (focused beam) device easily available which can be converted to what I want to do? I know some photoelectric detectors could maybe work, but I don't want to spend big dollars for testing. Any suggestions ?

You will likely want to remove the filter from the camera or use a different camera to see IR well.

Hi Jay Have you ever tried what I am suggestioning? I know you messed a lot with ir stuff.

I can confirm that you can remove the IR filter from the EZ-B camera but be aware of 2 things:

• The IR filter resides directly behind the camera lens and is glued in place
• The IR filter is made of glass (looks like a rainbow when viewed a certain angles)

In the past I've used need-nose pliers to squeeze the plastic a bit to break the glue from the glass but there have been times where I've shattered the glass filter. Please take the necessary precautions when attempting to remove the IR filter, use safety glasses and do the work above a small container to catch the glass.
