ArduCularis ready for take-off

After hours of painstaking work, weeks of researching and flying in airplane parts, and more money spent than I care to think about, I finally powered up my ArduCularis for a ground test today. The LEDs lit up, the ESC sang and the servos sprang to attention. A control surfaces test came out perfectly, flaps down, ailerons and rudder. The throttle and props pushed back…

Updated for ACM 2.5.3 and APM 2.3.0 - Unified Ardustation 2 With Parameter Editing, Antenna Tracking and Auto Detection of Arducopter or ArduPlane

This is an update from the original blog post in October 2011:

I've updated the Ardustation 2  source code to allow compilation with Arduino 1.0 Relax and the latest libraries for ACM 2.5.3 and APM 2.3.0. This update also includes a modification of parameter names for PID editing that match ACM and APM. The updated version is 2.0.12.

rotary engines for UAV

hi friends, on 14 October 2011 there was an exhibition organized by some 20 UAV manufactruing companies in New Delhi, India. It was wonderful to have something like this in India. The technology dispalyed was amazing. there were fixed wings and rotary winged UAV's. The show was won by this twin cylinder rotary engine designed for UAV's. The manufacturer claims to having nil vibrations in the engine. a very important issue for IMU's in the autopilot.  beautiful engine with circular cross…

Learning to work with EPS Foam


As I work towards building the GeekStar (My Geek Show's version of the Easy Star) I decided I needed a better building technique. This week I built a demo/sample of the EasyStar's nose section to see if 3/4 inch EPS foam would be a suitible build material and to see if a "layered" building approach would work, and in both cases: Yes!


The thicker foam is very hard to cut out with a knife, I'll have to build a hot wire cutter, but when it's…

Object Tracking - Proof of Concept

A few days ago I posted some videos of my object tracking algorithm, and some folks were curious how well it would perform if the object left the frame. Since posting I have hit kind of a breakthrough in the algorithm and it is working much better than I had ever expected. I am still fine tuning some of the sensitivities, but I added some neat…

Arducopter PID tunning howto video

Finally, someone has created a PID tunning howto video, from scratch to perfect stabilize flight, that I think will be very useful for the arducopter community, specially for those flying non stock frames.

The concepts are already in the AC2 PID tweaking guide developed by Jason, but a visual howto helps a lot!


The guide has been created by…

Magnetometer offsets revisted

The above is a plot of the 3 components of estimated magnetometer offsets computed during spin tests at 78 RPM of an improved method for estimating and removing magnetometer offsets. There is a report available with theory and implementation. The method will work equally…

Quadrotor: trying a few design ideas

My daughters and I have built several quadrotors out of aluminum and also a mini quad out of kite parts (see beatty-robotics.com for these). But for this next project, we decided to make a quadrotor out of carbon fiber. We applied everything we learned on our previous builds and also tried a few new ideas that we hadn't tried before. 


The arms of this new quad…

DIY Drones London Meetup

Thanks to Chris, according to many who had been at Number Twelve yesteraday was a very interesting meetup. One of the rare one's where you talk about everything from UAV's to how UAV's could be used to monitor eggs in bird's nest to export regulation of…

Homemade Hexacopter Powered by Arducopter

I thought i would share my hexacopter build with the world, it's not finished as of yet but it is getting there.

This is my second multicopter build; the first being a quadcopter which i may make a build log about as well but basically it was to see if my choice of building materials etc would hold up with the hexacopter project.


Components I am using:

- NTM Prop Drive 35-36A series (1800k/v @ 875W)

- HobbyKing Redbrick 80amp esc

- Ardupilot Mega…

New UAV to be reviewed by alishanmao

You're probably familiar with Al Shan Mao who vblogs on RC topics from China.  He's got a new video up previewing a UAV he will be receiving and reviewing.  Does anybody know anything about this unit?


  • full autopilot and GCS
  • 4 years of development
  • from "China's leading UAV makers"
  • interesting elastic-propelled takeoff…

Meet the Developers: Jose Julio

When we were first starting with IMU-based autopilots, the first thing we did was fly Jordi to spend a week with Bill Premerlani to understand the DCM and port it to Arduino. That was a great start, but we didn't really understand sensor fusion and filtering until we were lucky enough to hook up with Jose Julio, who is an international IMU rockstar…

My "indestructible" quad copter design.

Who am I kidding right? its almost impossible to design an indestructible quad copter frame! That's why this frame is actually the complete opposite. Its designed to fail! 

This is nothing new. Most designs nowadays are designed to fail, but they are designed to fail correctly and safely. There is always something that needs to be protected and for that to happen…

New hexacopter

Hi everybody,

I am starting with new hexacopter Project. It is my own project.. I am totaly beginer

an I hope, that project will be succesfull.

The frame is made from plywood 3mm, cuted with laser.

Last week, I ordered APM from jDrones.. I am still waiting postman.. :-) APM is on the way (on the air I hope) be cause I am from middle of Europe.

Motors will be AC2836-358 with 12X45 propeller set.…
