Shape Shifting UAV







The little airplane is able to withstand rough conditions thanks to three aeroservoelastic trim tabs, which are located on the trailing edges of the wings and tail. When the plane is hit by wind gusts, the tabs perform rapid high-frequency shape…

Playing With UDB LOGO

We've been working hard to make MatrixPilot ever more modular, and to test this modularization, I thought it would be fun to build a LOGO-like mission planning language as a plug-in replacement for the existing waypoints module.


After a few evenings of playing, I ended up with something that actually feels pretty useful. All the logo basics are there: HOME, RT, LT, FD, BK, REPEAT, etc. You can also set…

As most are aware , the only true constant in life is change . However the…

T3
rudder-roll stabilization

If you are flying a UAV DevBoard in a plane without ailerons, you should be interested in a recent revision to MatrixPilot that will tighten the turns in waypoint mode, without overshoot. The above picture is the track of a portion of a test flight in an EasyStar. The control mode was switched from stabilized mode to waypoint mode with…

Choose your equipment carefully.

With the profusion of low-cost components available today, it's tempting to pick the cheapest one that looks like it will do the job and not stop to think too hard about how well it's going to work. After all, if it's for sale and other people are using it, it must be OK, right?


Consider this post by the respected DIY ESC developer Takao Shimizu, talking about a low cost controller available from a popular vendor:…

Novel means of quadrotor control / adjust

Here's the demo of my gamecube remote controlling my quad. Newly implemented is the ability to adjust the PID.P value on the field using just the remote.



This method can be implemented with the analog remotes most people use. I've got another remote that uses only analog sticks to drive a menu system. Something similar could be done for the main AeroQuad project if anyone is interested.



The idea was that I wanted a durable,…

The journey begins

For my first post I thought I'd give back to the community (and edit later to add anything else I can do).



Viability spreadsheet



I'm pretty new to RC planes although I have had a JP Zagi for years but with it being unpowered I'm at the mercy of the wind and I'm still pretty jittery. Seeing the DIY Drones setup I thought it would help me become a bit more competent but instead I bought an EasyStar… Continue

Indoor UAV - 3D position estimation



Watch on Dailymotion

Hi!

The position estimation is not yet accurate (still bugs), but I am working to improve it. I also have lot of problems…

How to setup an Overo to work with your AP -- This is just a quick run down even though a long post

The gumstix overo is literally the size of a stick of gum.



This will show BASIC functionality of how to get the UAV DevBoard and the ArduPilot working. The rest is up to your imagination and the recipes you come up with and the add ons you want as well. I am sure there may be cleaner and better ways to interface the two but this was the easiest for me to be able to get the functions on board the plane i needed.



I will be showing you… Continue
