I've been experimenting with various IMUs like the MPU9150, but I'm finding it simply isn't up to the task. It's noisy, non-linear, and not repeatable. I've been using the excellent RTIMULib and calibrated the magnetometers, but it's still not what I need. I'm using it indoors which may be an issue.
You get what you pay for. I have a bigger budget for this project, so I'm looking for an IMU that can give me...
-Output of absolute orientation in Quaternions
-10Hz update rate
-Accurate within 5 degrees
-Repeatable within 2 degrees
-Ideally, serial output (to interface to an XBee/XN-XV)
-Physically, smaller than a deck a cards if possible
Sparkfun's highest-end seems to be the Razor IMU, is it up to the task? Other alternatives? Hoping to spend under $200, but could stretch it to $500 if absolutely necessary.
