Title: IR color sensors
Post by: Radiken on March 14, 2007, 11:27:37 AM

I'm starting a project to build a robot that solves a Rubik's cube. In order to do this, it needs to be able to recognize white, yellow, orange, red, green, and blue.

Is it possible to use a Fairchild QRB1134 IR Photoreflector for color recognition?
If not, what can I use to recognize 6 different colors?

It might be better to go with a CCD camera

Nice. Just for curiosity, where could I find some open-source Rubik cube algorithm? I know the solution for the Rubik cube but never tried programming it on a computer, and I am too lazy and buzy to do that.

so it's possible to do colour recognition by shining different colours of light at a surface. the idea is that more light will be reflected if the light colour matches the surface it is shining at.

it would be far easier to use a CCD camera though.

I think your best bet is to use the code for a program like this http://www.wrongway.org/cube/solve.html (http://www.wrongway.org/cube/solve.html) and just change it to fit you needs.

try this on this web site: www.robotroom.com/colorsensor.html I used this on a color seeking robot ones and It worked grate , and there are also links for other color related sensors.
