Would it be feasible to use a Wiimote sensor mounted on a pan/tilt platform to track a green laser dot in a room? If it is possible, what kind of range would it work at? I want to build a platform that allows me to use a laser pointer as a sort of designator.
You'd have to take off the IR filter from the Wiimote, which would mean it would see any bright spots.
Or possibly the frequency doubler from the laser, but then it wouldn't be green anymore.
I hadn't thought of all the effects of removing the filter. I've heard that a lot of cheap green lasers don't filter the IR light that they produce. Would this produce a dot of IR light?
EDIT; Actually, how small does the point of light have to be? Could I use an infrared flashlight?
Alternatively, Is there another way that I could remotely designate a target. Besides directly controlling the pan/tilt of course.
I know a lot of people have done similar things with a webcam and rasberry pi. But that I like the simplicity of Wii remote and arduino.
