This is pretty cool based on the specs.  Whats the physical dimensions though?

Finally! it is available to purchase from Farnell: IMU-6000. Been waiting for this for a while now..

I've been designing an integrated radio/imu/autopilot around the ITG-3200 and LSM303 but I think I'll use this instead

This nice SoC was announced some time ago, but looks like it's finally on the market.

A bit pricey on Farnell (even compared to its MSRP) but no doubt the chip count and board area saving are huge.

 

I would like to see an APM+Oilpan fusion into a single board using this chip (and cheaper than curren combination).

Something like ATmega256, IMU-6000, 3ax magneto and a few more things ina single board.

 

On the other hand, how about its fusion algorithm? How good is it? It means that it would strip down the calculs work to the ATmega?

It will be interesting to see how well the fusion stuff works, hopefully someone will do some sophisticated benchmarks before I get the hardware finished! Now I need to find a decent cheapo magnetometer which hooks up easily with the IMU-6000 - anyone have any suggestions?

That link is just for a pre-order....  InvenSense got a little ahead of themselves when they announced this a few months ago.

 

Ryan Beall and I have been working with Patrick Henry from InvenSense to get some good hooks built into the firmware so that this will work well in an APM oilpan ;)

@Thomas

how about the ubiquitous HMC5843?

@Doug

I am impressed how much ArduPilot team is involved in the industry!

This owns.  I must admit I've been eagerly waiting for it, and not-so-eagerly awaiting a stupidly overpriced sparkfun breakout board :P

 

Does the motion processing have filters running ?

We are just waiting for the SPI version to release the APM v2.0 around Q3-4

Yes, we discussed this last year when it was announced. It is not available now and won't be for a while. We've been working closely with Invensense and will be the first autopilot to use this chip. But using the built-in sensor fusion is not easy, since it wasn't designed for moving vehicles and centrifugal force is not corrected for. We're in discussion with Invensense about ways to input a GPS direction vector, but in the first iteration I suspect the chip will be used mostly just for the raw sensor data, not the built-in Kalman filter.

It's nice to combine the gyro + accel, but with modern MCUs I hardly see a need to offload the math. You can run a super-naive C floating point of DCM with like 5% of a $3 STM32.
