I suspect my first method for tuning PID loops was not a great hit because it required 3-view drawings or photos of the aircraft plus inertia data all of which is a bit fiddly. I've now got a new method based on flying the aircraft and logging accelerometer and gyro outputs in response to elevator, rudder and aileron doublets. This method works well with simulated data and I'd like to try it on real data. If you are interested in this experiment, let me know your email address and I'll send…Continue
As you've probably noticed, there are new features added to the Mission Planner almost every day (Michael Oborne is amazing). I thought I'd just highlight today's, which is neat. In the Flight Planner screen, your current Waypoint radius (the "hit zone" that qualifies as having arrived at the waypoint, which you can set) is…Continue
After some painstaking PID tuning and some near crashes, I decided to take out my octocopter and see what kind of thrust it was able to generate. After hovering for a moment, I gunned the throttle and the machine disappeared into the sky. It was beautiful. The only problem was that I had forgotten my Xbee receiver and thus had no telemetry data. My glee quickly turned into panic as I tried to judge which way the octo was facing and how to get it back. As it drifted further and further with…Continue
I try to launch it with a diy bungee launcher without much success, this launch has not damaged the wing but after the second launch i've to glue it (after a…Continue
I have uploaded a new revision of APM to the trunk repository (r3665) with automatic flap functionality. I am really pressed for time so am hoping some community members can do some flight testing on it and report back.
Flap functionality can be assigned to channel 5 or 6, using the…Continue
Overall width 680mm , length 840mm
About 5 hours work in it so far, the centre section and motor mounts are pre made for me out of 2.5mm fibreglass
The aluminium is all hand cut and drilled (lots of…Continue
CNET reports on a cool proof of concept--delivering life-saving drugs by UAV in parts of Africa where road are poot. I've advised that team that fixed wing UAVs might be a better choice for those…Continue
The aim this evening was to prove the new flybarless head with the ACM, and whether it would make a good deal of difference to the flight characteristics. We flew a full 5 min flight which is pretty good as the Heli is quite heavy now with all the extras fitted to it. Also i use a separate flight and main Power battery. a 2700mah 2cell and a 5000mah…Continue
Today's Developer is the genius behind the HK GCS, which you all know and love. We'd had ground stations before, but Paul Mather was the first to really do them right. I still remember the day he rolled out recording and replaying missions, which was mind-blowingly cool. And when he added voice synthesis, I felt a real surge…Continue
The Mission Planner will automatically load the new APM 2.23 code when you click on the plane icon on the firmware tab. The APM 2.23 source…Continue
Because I was searching a long time for an up to date APM +Remzibi´s OSD without success,
I made it by myself.
If you also like the new Version and dont know how to integrate remzibi´s feel free to use mine!
All Features of APM 2.22 are…Continue
If anyone thought the FAA could not move any slower on producing rules for sUAS...they were wrong. The last publication goal date was 11/17/2011...now the new proposed publication date is 01/06/2012 according to the Department of Transportation's website.…
Following discussions from a previous…Continue
It only took my JDrones kit from www.buildyourowndrone.co.uk a few days to get to Iceland. I started building it on wednesday night and it flew successfully on saturday morning!
(Apologies for the camera tilt) In this clip I am on the second 3000mAh battery and tentatively testing the altitude hold.…Continue
Today in Meet the Developers, please meet Max Levine, another graphic artist par excellence! You've all seen his work in the simple, stylized icons in the Mission Planner (see below), but he's also behind many of the diagrams and instructional graphics in the ArduCopter manual.
He's also working with…Continue
