FreeIMU 4.0 and MultiWii - Is your copter trusted enough to fly above your car in a confined space?

As a huge follower of Fabio and his excellent FreeIMU I thought it time to post an update. I am looking forward to playing with the final release. For those who don't already know Fabio, he is a pioneer and well worth following.

 

Extract from the blog...

First flights of FreeIMU v0.4

The testing of FreeIMU v0.4 is proceeding nicely.. finally my friends Tilman and Warthox received their boards and as soon as they could they mounted them on their quadcopters for some flying tests. They used the brand new MultiWii software which me, timecop and Alexinparis have produced... the result?

Judge it by yourself..

p.s.: huge thanks to Warthox and Tilman for their time in testing the boards and making the videos!

All I will say about that, is discussion about the new boards is not happening in the Arducopter list.  You guys know about as much as I do.

Sometimes, I wonder why the APM2 was developed, given that the natural progression is toward 32 bit processors. I suspect the lifecycle of APM2 might be short.

I think one of the core ideas with the APM2 was to use the MPU-6000 to offload the IMU calculations. Tests show that the Invensense DMP works really well as an AHRS IMU.

Ellison: The hint is the "Ardu" part. If you understand why Arduino has dominated the exploding DIY electronics market (blowing away all the 32-bit boards), you will get why we follow the Arduino roadmap. It's not about "feeds and speeds" --it's about community, ease-of-use and accessibility to all. When Arduino moves to ARM (later this year) so will we, but not before.

Chris, yes it's definitely a plus to keep within the "Ardu" environment.  I would hate to have to move to any of the proprietary or Eclipse environments.  My current information about the AQ Baloo is that Maple is being ported to it.  Ted, has been testing the code already.  I haven't followed the Baloo progress in the last few months, so I'm not sure of the latest information.  If indeed the Maple port has been completed, I'd probably get one, since I sourced the prototypes, myself from SOC Robotics, in Vancouver. We're not as much on the fast lane as Silicon Valley, I'm not used to product lifecycles of a year. ;-)

Well if you get to a certain chinese resturant on Saturday hopefully Mr Arduino (Massimo Banzi) will have something interesting to tell you :) Obviously with the ARM annoucement from Arduino at the end of last year, Saturday, might be a good day for all :)

Chris, for those of us new to the scene (me) why is Arduino dominating the market?  All I see are criticisms from some "experts".

Comment by Ellison Chan on May 18, 2012 at 2:01pm

Fab, there's a Chinese restaurant in Italy?

@ Jason J "Ellison, yep i know. I have seen few NAZA's flying. But you also need to remember that NAZA cannot do any navigation/auto take-offs/landings and things like that. It's just mainly a flight stabilization system. Could we be better, sure…"

 

You might need to rewrite this soon, new NAZA with GPS, RTL and IOC........

Martin, in fact any autopilot can be upgraded to have nav, like the navi board for KK.  I was actually thinking of modifying the AC code so that it provide yaw/roll/pitch/throttle to the Naza.  The AC can do all the navi functions, and since we retain yaw/roll/ptich/throttle all the way down the chain, until we actually set the motors, the code would just set the controls, using four of the motor channels, instead of actually setting the motor pwm.  However, because of the "vario" throttle on the Naza, as I've discovered, elevation/throttle output from the APM may have to be modified.
