Hi there! Finally you can pre-order the ArduIMU V3 here.. You can find more info abut it in my last post here.
The final version of the board for full production is here, I'm expecting to start shipping them this Friday or Monday.
We are still working on documentation and giving the final cosmetic touches to the example code to have it ready before you have one in your hands and at the same time we are shipping samples to developers to do a full DCM integration.
From now on our new color will purple! All our new products will feature a Lilypad style look!
(Note: this is a stand-alone IMU, and is not designed to be a replacement for the "Oilpan" IMU shield of ArduPilot Mega.)
Comments
I'm glad to hear about the ability to include GPS data in the DCM calculation, but I hadn't seen any reference to that capability in the posted documentation. That makes me wonder what other undocumented features the chip has.
Is there more documentation available for the MPU-6000, beyond what is posted on Invensense's website? I noticed they just posted the Register Map doc in the last day:
http://invensense.com/mems/gyro/documents/RM-MPU-6000A.pdf
Hopefully they wouldn't require an NDA to get access to additional documentation.
Purchasing the hardwear was easy The architecture to the software is hard.
You guys need to relax with the price issue. Whats 18 dollars...Come on already , this is all open source hardware and software..What more do you want
I'm starting to buy hardware for my firstever quad. Could anyone please tell me, would I be safe to order this + other electronics (without the ArduIMU V2)? would that make a functioning system? (http://store.diydrones.com/ArduPilot_Mega_kit_p/kt-apm-01.htm minus ArduIMU2 plus ArduIMU3) ?
I don't get the needless sensitivity. I don't see a reason for any apologies. The price is what the price is, that is what it takes to produce and sell it. It's not meant to insult anyone, and it is great that it's open source. If someone thinks they can make it cheaper, fantastic. It's not an insult, it's an opportunity and an earnest challenge, for the benefit of the entire community. What's the fuss? (That is a rhetorical question.)
@Mike: My ArduIMU quad is not documented here, but use the blog search and you will find a lot of information on work by others. For example: http://diydrones.com/profiles/blog/list?q=arduimu+quad
@John: I am interested in a quad that uses just the ArduIMU as I want it to be small and use brushed motors (I know that is not a popular choice) and of course I would be using v3 when available. I have built small quads (about 3-4" across) but nothing Arduino based and this seems like a good option - just need a tiny receiver. Can you point me to your projects you mentioned. Thanks!
Wow. That sounds excellent
Alex: We've got that covered. The code just uses the GPS information to send a accelerometer bias correction to the MPU-6000 internal sensor fusion processor. We can also send in magnetometer data if desired. We've been working on this for a while, including with the Invensense team, so we've got a lot of experience already. It's a great chip and you'll notice a significant performance improvement.
@John @Chris : Ok good to hear the code will support both methods out of the box. One concern with the MPU-6000 calculated attitude is that since it doesn't have access to a velocity measurement it would not be possible to correct for translational or centripetal accelerations of the vehicle. For example, a constant speed, steady turn would eventually cause the roll estimate to drift in response to the centripetal acceleration.
