I think its time for a new DIY Drones contest which I would like to propose.
The T3 is fun, but it doesn't have any real point other than the winner gets some bragging rights.
At the end of the day, speed is not the goal for most of us so a competition that measuers speed yields no useful information that helps us move forward as a group.
The contest I would like to proprose…Continue
A large scale Variable Pitch Tilt Quadrotor implementation.
An update on the navigator concept:
I think the screen shot is interesting.
On the left is ArduPlane Desktop in default config, running the "autotest" mission at 1000hz perfect world data.
On the right is the…Continue
After a successful first year of the Mr. Lifter contest in 2011, a new contest has been launched for 2012. The contest has many categories you can enter -- from 'heavy lifter' to 'all out time duration', 'most weight efficient', to 'largest copter' to name a few. One category that is new for this year is the "furthest distance" (round-trip) in a single charge. Perfect…Continue

I would like to fly with live video and goggles, but this makes it tough to make any changes on the mission
planner. To avoid any need to take off the goggles I integrated a series of menus in the OSD.
My setup, as reported…Continue
Here's a cool hack of the Parrot AR.Drone using the EZ Robot controller board (a PIC32 board with bluetooth and some very easy to use desktop software). It tracks the color red and chases him around the room!
Last year me and a friend of mine started building a quadcopter from scratch. We wanted to build the machine and the electronics ourselves. We experimentad a lot, but up until today we did not yet succeed in getting the bird in the air with the home build electronics. We keep having some trouble reading the data of one of the sensors, thus the PID loop doesn’t work properly. More information about out QR1 quadcopter can be found on …Continue
With the new fast prototyping tecnology is possible to develop new technology from the concept to reality . With high performance DIY electronics and 3D Design tools today is possible to obtain this kind of result.
This is our experience :
We use some 3D Pro as EdgeWorks or Solidworks and Opensource Tools as Bleender for design the frame.…Continue
Following up on the success of my relay low battery warning leds I have expanded that code to include a complete lightshow and to be compatible with the newest ACM codes (2.1.1) and the APM1 hardware. APM2 hardware MAY work, but I don't have APM2 at this time,…Continue
Finally I've managed to have some time and do a little flight to test the Arducopter v2.1 firmware.
Here is my quad and some specs I hope you find them usefull somehow :
Weight (with camera on board) : 1700gr
Weight (without camera) : 1500gr
Battery : Turnigy 5000mAh 3S / 30-40C
Motors : 4 x EMAX GT 2812-11 930KV (about $15 each from plus2city - behaving very well so far)
ESCs : 4 x AE 30Amp (about $12 from hobbywing, behaving surprisinglly well so…Continue
This definitely counts as more sci-fi than practical reality, but a South Korean team has proposed using a cloud of "robotic bees" to squirt building material to form structures the way bees make nests. …Continue
This is awesome and a great candidate project for the PhoneDrone Android/RC interface board.
From the creator:
Recently, I have been refreshing my knowledge of…
While looking at new products on GlobalSpec, I came across this sensor from Delta Metrics. Delta Metrics (a subsidiary of tecsis DBA) has created a single sensor to measure both static and dynamic pressure simultaneously, reducing the complexity of implementing an airspeed sensor. More information is…Continue
We often get questions from newcomers who are confused by all the Ardu* nomenclature here, so I made the above product comparison matrix, which you can find here.
And just to extend this to the full family, including…Continue
The 2012 AMA Expo (happening this week) will be featuring the NASA DROID, a drone that's being used as an educational vehicle for high school students.
Come and see and learn how NASA Dryden Flight Research Center uses the DROID or Dryden Remotely Operated Integrated Drone for flight research, pilot training and the INSPIRE student internship program.
The DROID is one of four aircraft used for…

Gyro stabilized mount works quite well. The roll servo does seem to be a bit jerky, but from the forums it seems its one of the downsides to digital servos. What about a small air shock absorber? A trade off of reaction time for fluidity of movement. Although, the platform is for photos not video...
A somber ceremony begins, as the machine which caused Major Marcy to sever all contact with us is dismantled & returned to its role as an aircraft position tracker.
The construction of an indoor test harness greatly…Continue
Just built a suprisingly good flying quad. Total price with battery but without receiver and APM was $127. It's very usable indoors and later I will add GPS mag, xbee and fpv tilt roll cam today.…Continue
Happy new year!
I've put together a proof of concept autopilot based on the Lyapunov Vector Field path following stuff documented in various UAV research papers of the last many years. It is here:
a) it can fly JSBSim,…Continue
