Re: Noisy Accelerometer
We're seeing the same kind of jitter in the accelerometer from this years KoP. In all directions (x, y and z) we are getting odd values for an at rest bot. The nominal values are suppose to be 1.5V at rest. X is 1.84, Y is 1.76, Z is 1.74.
I tried resting the accelerometer on the ground, away from the bot and no change. I swapped the accelerometer with one from 2005, and while there's a little jitter it's in the +/- .002 range.
Now the new on is more sensitive (300 mV/G) and it's possible that we need to replace the bandwidth filter on the board, and isolate the board better but I'm leaning more toward that the board is broke.
