APM Mission Planner now also serves as ArduCopter 2 Configurator

We're getting ready to launch the beta ArduCopter 2.0 (formerly known as ArduCopterMega, or ACM), and much has changed. First, it's our first real quadcopter UAV code, designed from the ground up for fully scripted autonomous missions as Jason's runs at Sparkfun demonstrated. It's also totally built…

Microsoft ICE: a free PTGui killer?

I've been using the PTGui software ($121) for years to stitch together aerial shots into composite mosaics, but noticed in Krzysztof Bosak's post that Microsoft Research had something called ICE that could be an alternative. I…

Quadrocopter's third flight with the GoPro

I tried flying with the GoPro mounted this time. I already had broken part of my landing gear last flight but managed to hold it in place with some duct tape ;) Everything went ok until I broke the landing gear again and had to remove the camera mount not to break it. I did a couple of flights without the camera and with the broken landing gear until I snapped 3…

How the land changes as we repeat mapping during the year

Dear all, during routine test flying of Pteryx UAV, we had an opportunity to capture maps of various sizes.

The following example is made near our factory in Opaleniska village, South-East Poland.

One thing is clear: Google Earth is lying! The earth from above never looks as it shows.

The original is here:…

Charming story of building an aircraft launcher

After failing in my autonomous rise-off-ground launches at Sparkfun and seeing Doug do so well with his catapult, I've been thinking about building my own launcher. So was this kid. Watch his research, experiments and ultimate lessons. A really nicely done… Continue

My seconds twin boom attempt

This is my second attempt at a twin boom. Made from 9mm depron hot glue and nylon re-enforced tape, with a 2m wingspan. The wing is a KF2 profile with a single c/f rod for stiffening.

Running a 2200kv motor 8 inch prop and 2200mAh battery. Weighs in at a tad under 650grams. Had the motor running at about 60% throttle for over 25 minutes. At full throttle it can almost go vertical. I haven't decided what features to have in the nose cone yet so its just curved…

First round of frame modifications!

Hey all, though I might share the attached photo with you to show off some mods I've been working on whilst I wait for spare props to arrive from Thailand, after not loading code properly and flipping the copter on its maiden voyage.

Widened the landing gear to more stability, as well as increasing ground clearance for my GoPro, converted the dome to just two complete…

My stuff have arrived!

Previous wednesday, my APM arrived, but I haven't got any time to take a look at it. As soon as possible I should solder the pin headers, so that I can do some testing. Yesterday my motor and batteries came, which means that I hopefully can get the plan into the air by next week.

Below is a picture of the plane I am going to use. It's my brothers old .20 model, which I found of the loft and I have got his permission to use it. It haven't got airborne yet, although the plane is…

Start as you mean to go on -- The Coptermatic Chronicle Part 1

Minor background before I start.  

I've been playing with wheeled robots for a while, using the Basic Stamp as a controller.   Just tinkering, and more interested in the software side of things (as well as having something that annoys the cat).  My enthusiasm died out about 7 years ago, then my son gave me a Lego…

Yet another Build log - Epp FPV

So my kit from HK arrived yesterday and I should note that this is my first build ( If you see terrible mistakes don't hesitate  to shout;))


Soldered the carbon rod using some super glue. I installed those holders just in case even though most probably am gonna put the elevator end radder servos on the wing itself

Remzibi OSD and video + radio RSSI

In fact with my installation , i am using currently 2 Remzibi OSD.

-The one in the plane is standard with a Flytron Current sensor which is measuring the Instant consumption and the Average current consumption + Radio RSSI + Home + plane battery voltage + Radio RSSI + GPS Altitude and speed.

-The other OSD is for the Ground station and currently i am using… Continue

DIY HEXA power distribution PCB

Hexa frame adventures continue !


This time I've prepared the power board that will distribute power to all 6 ESC's and to additional devices (video TX, camera controls receiver unit, tracking system TX, LEDs and more...)


Important issues were: Lightweight, simple, high current, fail-proof.

MatrixPilot 3.0's Improved Navigation

This is a screenshot of part of one of my MP3.0 test flights from yesterday.  The plane was programmed to fly figure eights, using the UDB Logo program below.  The GPS track is shown at 1Hz, and the dead reckoned IMU track is shown at 4Hz.  The plane had taken off very recently when it started this track, so it was still calibrating for the wind speed. That's why the first side of the…

More details on Minuteman

GPS vs. Dead Reckoning
So, I decided to try the bare minimum first, then add complexity as needed. It turned out that dead-reckoning worked pretty well. With some refinements, I think it will work REALLY well. Also I came to the conclusion that heavy reliance on GPS will doom any bot to slow speeds. The…
