First FEZ-IMU Demo!

This is the first baby step towards a full working Quadcopter - testing the IMU!

On the computer screen it shows two Artificial Horizons. On the left, it’s the raw output from IMU Accelerometers, and Accelerometer/Gyroscope fused data on the right. The filter used here is the simplified Kalman filter developed by Starlino.

Things are getting more and more interesting!


#2

Which IMU unit is that? the filter looks spot on.


#3

It’s a 6 DoF ADIS16350 Digital IMU from Analog Devices. We salvaged from some senior design groups previously working on a similar project. This thing is expensive, however Starlino used an Analog one and it works for him.

holy crap that looks accurate! :o

Cool! ;D will you use this for rwar?


#7

Chris: I would like to see how you will filter the result. Accelerometers and Gyroscopes are two little bad boys, you have to decide who to trust more to get better results.


#8

Yep, using for RWAR. I don’t intend on filtering past the AHRS code. The data looks pretty clean already.
