Experiments in Autonomy

Sometimes a flight experiment gone awry exposes a set of behaviors that directly correlate to previous design choices. It's a moment of validation based on developing systems with the expectation that they will fail. The video below is an example of one of these moments.

During one my daily experiments with multiple robots, one of aircraft experienced a GPS interference…

How to avoid pitfalls when using taper and twist

Hey guys,

Just put together a quick video to show the effects of taper ratio and twist and how they interact. Turns out using rules of thumb in this area can be detrimental. I have used similar rules of thumb in the past, but thought it was high time to walk through some rigorous calculations to see what's best.

Hope it's…

Copter-3.3 ready for wider use

After months of testing by the beta-testing team, Copter-3.3 is ready for wider use.  Similar to the Copter-3.2 release this is a "soft launch" meaning that for the next couple of weeks, we are asking users to load the new version using the Mission Planner's "Beta firmwares" link…

Free Android App for UAV's

New app available for UAV pilots.

This app contains over 46,000 airports around the world which can be displayed quickly and easily when flying RC models. When flying RC/UAV's commercially, these areas are considered "No Fly Zones" based on your geographic location.

For example when flying UAV's in Canada, Transport…

Micro Drone of the Future

I've been looking at micro drones lately and I'm now sure it is likely that the future of the drone is the tiny drone much like this mechanical dragonfly.

With the use of very tiny piezoelectric actuators that draw very little current I believe it is now possible to create these very tiny flying drones. …

PaparazziUAV and Multiple MAVs in Flight

A few weeks back I posted about flying multiple robots along with my Periscope channel where the videos age out on a daily basis. Some folks requested a more persistent video of these flights. Yesterday, I went out to the field and did a few flights. My friend Max was nice enough to film one of the multi MAV flights, and I took the initiative to archive it on…

Why sweep hurts endurance and what to do about it

Hey guys,

I just wrapped up a project that taught me a lot about the effects of sweep on flying wings. Turns out sweep can significantly increase drag and hurt endurance. Sweep isn't all bad, though. There are ways to make a flying wing stable if you do it right.

I put together this film to explain the physics of what's going on and how to get stability without sacrificing endurance.

Hope it's helpful.…

Nica Drones Mag Lifter EPM 688 Next Steps.. We made IRIS do it

I had posted the following blog for developing possibly  real application. My partner Ian, he is a bit of a jock and does not want to give up. Anyway, using Spektrum DX8, he was able to hook up the Mag lifter to "Pick Up and Deliver Cargo". You can see the video on our website.

There are couple of issues remaining-

1. Copter being not very stable, was not…
