Wii360... perfect example for RC?

Just to take the neg rep burden from Lil Lavery...

It's a cool project simply for its amazing ability to hack together many disparate elements, but I entirely agree with Lil-Lavery: Using a motion-sensing apparatus such as a wiimote to control your robot seems a bit counter-intuitive. I understand that there are teams that did it this year (one at GTR even made homemade wiimotes), and that is certainly innovative, but from my experiences playing my wii, I can't see a real fidelity advantage over other methods.

Since the accelerometers are the 2nd derivative of what you presumably want to measure (the position), then you've got to do lots of computationally intensive and potentially error-inducing integration to determine your position. Building a little model of your arm and tricking it out with potentiometers would allow for direct manipulation of your on-robot arm from your OI.

Sure you could use the accelerometers to infer the exact orientation of the remote (as many games do), but that can be tricked into innacuracy simply by the remote shaking a little (lateral or longitudinal acceleration would be misinterpreted as the remote rotating).

It would be an excellant off-season project to learn about custom circuits, programming, and about electronics in general, but I don't see any great advantage over more conventional methods.
