Time for a new contest....

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…

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…

"Mr. Lifter" Multi-Rotor Contest for 2012

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…

Ardupilot control using OSD menus



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…

Camera tracking with an AR.Drones and the EZ-Robot controller

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!

QRM [DIY quadcopter]

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 …

From Concept to reality with Multipilot32FX and 3D Printed single body Frame FOX 5 Multiquad (First Flight impression)

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.…

U4eake's showleds, arming and low battery warning leds

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,…

My quad + Firmware Arducopter 2.1

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…

UAVs as robotic construction drones

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. …

Single Sensor For Static and Dynamic Pressure

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…

NASA drone to be featured at upcoming AMA Expo

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…

APM 1 and gyro stabilised Photoship One MTR Pro Camera mount

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...

Proof of concept cross-wind navigation (and low level) autopilot with vector field surface tracking

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:

http://i.dslr.net/vectorfield/autopilot.html

It is written in javascript can can operate in one of two modes. It is only tested on Chrome.

a) it can fly JSBSim,…
