called a light pipe ,very cool idea .led on one side and the whole tube lights up.and is bendable

led light pipe it comes in clear and white

Imagine the white is cut out and backlit. I don't think anyone can really say this looks intrusive or like it doesn't belong on the back of a charging dock. Not sure if the EZ-Robot font is right but it's a concept at the moment.

I've just printed it at 4" x 4" and will attempt to cut out, light up and test when it's dry and I get chance.

Looking at it 4" x 4" is really quite small so if this does work then it's suitable for pretty much any size robot.

Second thoughts, I think a glyph may need to be simpler than the symbol I put on there...

I was actually searching for info on glyphs and come across this topic

And more to the point, this video;

That was an interesting topic navigation unfortunately was forgotten by the wayside, I think that navigating targets in individual topic is very important to "go" to the charging station, not to "try to find" unnecessary circling. In my humble opinion, we can kill two birds with one stone if we solve the issue of charging station with the theme of navigation or the reverse.

YES thats all been my idea from the first

That vieo you have doesnt show GLPHS it uses wall and other stuff to navigate using a camera

kinect camera uses that design using a laser and a camera,DJ said he is working on a interface,but having problem getting it to work.

I trust you meant to write "That's been my opinion from the start"?.. Unless you really are trying to take credit for everyone else's ideas and suggestions.

Who said it showed glyphs? It's an interesting concept.
