Arducopter Maiden

by on Mar.09, 2012, under Everything, Projects, Unmanned Aerial Vehicles

Finally had a nice sunny day to take my Arducopter for it’s first flight!

It is not as stable as I thought it would be; most of the flying time I had it in ‘loiter’ mode which attempts to maintain a position based on GPS and altitude (using either barometer or sonar).  Even so as you can see from the video it moves around quite a bit still – next time I’ll take my laptop to make sure it has a solid, accurate GPS fix before launching.

Three flights in total, the last one had a hard landing which flipped the quadcopter throwing a prop; all fixed in just a minute ready for the next flight in a few days.

Adrucopter Build

by on Mar.05, 2012, under Everything, Open Hardware, Technology, Unmanned Aerial Vehicles

My recent obsession with Arduino brought me back to an old interest: autonomous flight!

I totally love the open source community and the great stuff that people throw in together on…such as DIY Drones.

DIY Drones is a community built project using Arduino microcontroller to control a multi-rotor helicopter (though it also can control a single rotor heli or fixed wing aircraft).  A dedicated Arduino board (ardupilot) connects to an IMU sensor board which contains minuscule gyros that sense the orientation of the aircraft and the built in software responds to changes in attitude by adjusting the speed of separate motors.

I have added GPS support and a magnetometer to sense magnetic heading, along with a bunch of pretty lights that help identify which way is front!

The airframe and parts are from jDrones; the software and instructions are all contained on the Arducopter Wiki (including a couple of good guides on adding in LEDs).
