About Me:

Lead developer of ArduCopter. I coordinate releases, provide support for users having trouble with their copters, add new features (most often based on ideas and suggestions from the community). I also help others get their code integrated into ArduCopter. You can find numerous video tutorials from me here: https://www.youtube.com/user/rmackay9/videos facebook: https://www.facebook.com/groups/ArduPilot.org/ gitter: https://gitter.im/ArduPilot/ardupilot/

Please tell us a bit about your UAV interest

Interested in quads and helis mostly. I got my start in this field by reading the electronics tutorials from Sparkfun and from watching the success of Jack Crossfire's vicacopter. I've learned an enormous amount from the combined wisdom of the people on the DIYDrones forums and members of the core dev team including Jason Short, Tridge, Doug Weibel, Leonard and many more.

Randy replied to Ray's discussion bad crash last Saturday - can someone here read logs and analyze ? in IRIS
"I don't spend time on DIYD anymore, normally I'm over on discuss or one of our other communication channels.

In any case, I wanted to let you know that Peter Barker and I have seen this and will look into it.  I've raised an issue here."

Randy replied to William Billings's discussion APM 450 Helicopter tuning in ArduCopter (traditional heli) user group
"It may be better to get support on the ardupilot discourse server: http://discuss.ardupilot.org/c/arducopter/traditional-helicopter
code for the APM2.6 is pretty old now.. >2years I think.  Best to get a more modern flight controller.…"

Randy replied to George Piper's discussion Uploading Problem w/ Programming APM2.5 using Arduino IDE
"Best to join us over on discuss.  Also best to give up on the AVR boards and move to something more advanced like a Pixhawk or NAVIO2 or something like that."

Randy replied to George Piper's discussion Uploading Problem w/ Programming APM2.5 using Arduino IDE
"maybe try this link? avrdude.conf
by the way, few of the ardupilot developers use diydrones anymore.  better to look for us over on ardupilot.org. or in particular to post questions in the ardupilot forum."

Randy replied to Carolina Monterrosa's discussion Drone loses configuration in ArduCopter User Group
By the way, ArduPilot support is mostly done over in the ardupilot forums now and most developers don't spend much time on DIYDrones anymore.
I think the issue is likely a damaged Fram chip on the board (somewhat unlikely) or that the…"

Randy commented on Randy's blog post Terrain Following Missions using Lidar
"@BretC, yes it does (see wiki here).  By the way, we've moved most ardupilot support over here to the ardupilot forums and I don't think you'll see most of the core ArduPilot developers here much anymore  The servers are a little slow but they'll be…"

Randy replied to Bob Smith's discussion APM 2.8 landing gear retraction in ArduCopter User Group
"Hi there.  Most support for ardupilot is being done over in the support forums I think although no guarantees of a response. http://discuss.ardupilot.org/
I think the easiest path to happiness probably involves getting a more powerful flight…"

Randy commented on Randy's blog post Copter-3.4 beta testing starts
There have been many changes for sure including some in MAVLink.  Perhaps it was the addition of MAVLink2?  Or perhaps some messages were replaced by others?  If it's MAVLink2, I think only -rc6 has it as the default protocol, -rc7 (coming…"

Randy replied to Tony Kenward's discussion Leddar One optical range-finder support coming to ArduPilot? in ArduCopter User Group
"In an interesting turn, a pull-request has come in for the LeddarOne.  I think it's a new effort, separate from what Anton has done above.  Not sure if I'm being cheeky or not but maybe Anton could look over this PR?  It's perhaps a bit of a shame…"
