not only did we have great sucess, but we can control turning, distance and speed down to 1/4", and its shorter, faster, and simpler then writing a gyrp algortiom. 2 intrupts, 2 banner sesors, 2 wheels, 2 variables. lol thats it.

That way you don't need to waste cycles on the RC integrating the gyros, and counting the encoders, etc...

for next year im working right now on a pic16F84 in basic (yea i know; shush up) to integrate the gyros (2x) 2 banner sensors (for the wheels) and a compass. it will output the data in rs232 format as (speed)-(direction) every time its polled, and a (time)-(distance) may get built it soon. i might
might write a white paper on it if i can pass history
