Slung Load Control with a Quadrotor

Just thought I would attach a video of my senior project. My partner and I used an AscTec quad to control a payload swinging underneath it. Purportedly, we were doing it to demonstrate that you could fly a helicopter and slung payload waaaay faster if you had one of these controllers running. Really, it was just a fun project. Check out the video:…

HK GCS now supports APM binary and UavDevBoard (Matrix Pilot/Serial UDB Extra)

Recent additions to my GCS include the APM binary stream and the UavDevBoard (Matrix Pilot/Serial UDB Extra) data stream plus playback of UDB text file on the Data File tab. Quad model is also a new addition (many more models coming soon). Screen is now resizable and depending upon the instruments size, either the glass cockpit or 3D model can be clicked and selected as the "big" instrument. Minimum screen size is now 800X400 which should work well on older laptops and… Continue

STMicro Cortex-M4 Samples Coming Out!

STMicro has done it again... this time readying their ARM Cortex-M4 MCU (with hardware floating-point, DSP instructions and compatibility with Cortex-M3) for production in early 2011. In addition, they're also expanding into the F-2 series, which features an adaptive real-time memory accelerator to achieve a performance of 150 Dhrystone MIPS when executing code from flash at 120MHz (the maximum possible for the Cortex… Continue

I2C is delicate, I too see

My first attempt at communications was going to be I2C, with the ArduIMU as a writing master, and the Nano as a reading slave. I had hoped that the 5V nano would be OK with the 3.3V magnetometer, but COMMs were never achieved, and it seems to have damaged the mag.
So, back to serial, while I wait for FedEx to bring my early xmas gift.…

AMA membership mandatory in new regulations?

The AMA is claiming that the FAA has "forced" them to become the "manager" of recreational aviation that will force every recreational sUAV user to be a member of the AMA or not be able to fly.

From one of the AMA's "ARC" FAQs:…

Getting started - First steps into the UAV world

As a total newbie into the world of electronics hardware and software, I took the big step a few months ago of deciding to build myself a UAV. Actually, I decided to build myself a quadcopter after seeing what was to become the ArduCopter on Hackaday, but the dream changed and the desire for payload carrying overcame my initial desires.

Anyway, I ordered myself an Arduino board and set about going through the learning examples,…

Arducopter arrived at home

Just wanted to share my excitement about the arrival of my Arducopter.

Want to thank and congratulate with Jani for the super fast shipping (despite one month of wait in the pre-order list): the box left the office last Friday and this morning, Monday, 3 days later with a weekend in between, it arrived at my place, in Bruxelles (Belgium)

Here is the content of the box:…

Angle of Attack and Sideslip angle estimation from ArduIMU V2+ and GPS data

Hi, I'm wondering if there's a way to obtain AoA and sideslip angle information from GPS speed data? There is vertical speed and 3d speed so this would probably be able to give me an estimate of the angle of attack, but for sideslip, I would have to have the y-component of the speed. Is there a way to get this from GPS or the IMU unit?

I have also tried it for one whole day but am at a loss of how to get the information to be passed from ArduIMU V2+ to ArduPilot so that I can…

Drive 10 Servos using only 2 Arduino Pins

I've been building both AutoPilots, and QuadraCopters, and I wanted to drive more servos and ESCs, with less jitter, so I used some ideas from the Paparazzi gang and developed a way to drive up to 10 servos with just 2 output pins from an Arduino or ATMega8.

The design uses just one chip, a Johnson style Decade Counter, and requires only two output pins from the Arduino. The Arduino uses one PWM pin (pin9), and one general IO pin (pin8). All the pulse… Continue
