The WiiCamera only tracks IR light not just light. It can see up to 4 IR light sources. Some smart people have used it to do basic triangulation. It's pretty accurate for smaller distances.

I have made a much simpler version of this using LDRs but your's is better as my  robot needs the light to fall on it. Wait a second, mine is also powered by a cell phone battery. I wanted to verify if it is safe to use cell phone batteries.

I have been using them tons and I have no issues. Do your homework and don't over charge.

Do not copy to much of my code, I'm a very bad programmer :) To integrate the SR04 sensor I mixed these 2 sketches together:

and this sketch:

I have it set up that when the WiiCamera does not detect IR light the robot start driving around and avoids obstacles.

Yeah I had all these old cell phones laying around and needed a project so I started playing with a couple... the next thing ya know all my robots have them and they were free.

Very nice bot! Just wondering what the material is used for the base?

It's black foam board from the office store. Just paper and foam. I also used hot glue, aluminum L, and a cord lock for a caster.

Looks like fun. Like the target "Indoors and flat" - I can understand that one.

Still waiting for my cam from Rocket Brand and having some fun with it too.
