Now with the camera and these sensors and trig functions, you could easily push the RC to its limits, I think.

So far we've got a program that's running fine with six encoders (each generating around 1000 pulses/sec), the gyro, some prototype DAA code, the camera, several PID controllers, and a bunch of math using (floating point!) trig functions, and it all fits comfortably on the RC so far and is working fairly reliably (the camera occasionally goes off into la-la land for as yet undetermined reasons, but if I reset it and the RC it's always fine). That said, this is just the nuts and bolts, getting all the code ironed out, the PID parameters properly set, and autonomous mode working are going to take a lot of time and effort on the part of several students.

I suspect that if I need too many more trig functions or the code gets too slow, we'll have to address the issue (probably by replacing the floating point math with fixed point trig routines), but for now I'm pleasantly surprised with what this year's RC can do.

How accurate do you think you can go for a navigation system using the gyro and accelerometer? I want like 1 cm resolution at 10m/s, on paper at least.

Whats DAA? and What do you need 6 encoder for(at 1000 pules/sec)?
