Louis Legrand recently ported the direction-cosine-matrix firmware that Paul Bizard and I developed to the "IMUDOT", and made a video of a demo.Louis, thank you so much. Thank you.The video speaks for itself.Bill Premerlani
Louis, can I ask what model accelerometers, gyros, and magnetometers you use for your IMUDOT? Do you apply any analog or digital filtering (poles, cut off frequencies)? What ADC sample rate do you use for the sensors?
Let's put it that way. Truly Amazing IMU. But... From our point of view, it is as available as Procerus Kestrel. In fact not available at all. If we rank it among other IMUs not available for mortal being, I bet the one in Space Shuttle is more impressive as it is radproof and requires no acceleros.
"Regardless, it is nice to see Bill and Paul's effort in the hands of a giant like Intel. That speaks for itself!"
And now comes the lack of GPL. Soon Intel is going to announce the new processor that will be able to tell if it is being thrown into the thrash in order to start negotiating early.
I agree with OliverD, for the most part. The InertiaDot was not designed for UAV's. It is mostly designed to be worn by people. Further, it uses some pre-production parts from a company I cannot name (we signed a NDA). Bill's UAVDevboard is definitely the way to go for the diyDroner. Bill's code is first rate. As a point of reference, our previous generation IMU code used the majority of a 32 bit 400MHz XScale. The InertiaDot is running on a 16bit 8Mhz MSP430!

@OlivierD,
Thank you for your kind words.
I basically agree with you, although magnetometers would improve performance when making turns in strong winds. The ideal combination is a GPS, 3 gyros, 3 accelerometers, and a 3 axis magnetometer, but it would be only a little bit better than GPS, 3 gyors, and 3 accelerometers, if the GPS responds quickly.
Sure. I appreciate the budget consideration. That said, for the helicopter I'm working on at school, a board like this (not with bluetooth, definitely a wired connection) combined with a Novatel GPS is actually pretty appropriate.
The devices we develop at Intel Research are not typically sold. They are built to facilitate the various research project that we are working on here in the lab (unfortunately no UAV's). However we do occasionally share devices with other researchers. See for example http://seattle.intel-research.net/msp/ and http://www.seattle.intel-research.net/wisp/ for examples of this kind of collaboration. I am hopeful that we might do something similar with the IMUDOT some time in the future.

What gyros are you using? It is good having them all on the same circuit board without having to mount vertical boards.
