Hi Folks,
I am from Netherlands and want to purchase Arducopter kit from near Netherlands. Is there someone from Netherlands working on Arducopter(s)? It might be better interesting if I can find someone to contact here.
Also, I am a bit confused about

I have a quick question. My budget for a transmitter/ receiver pair is +/- 100$. I can see that there are really cheap ones out there, but I would like to ask you about the compatibility, performance and failsafe usage with Arducopter (i.e. A

During the Arducopter purchase I noticed that I have to make some choices:
My requirement is to fly the quadcopter with GPS (for waypoint navigation), sonar (for height sensing) and IR (for object avoidance). I may go for a Hero2 camera with a

Although, I have experience with quads, I am going for my first purchase (ready-to-fly) kit for Arducopter. I thought better ask the community on where to purchase, Udronesor jDrones or buildyourowndrones based on their experience. Factors

I am doing some research on building 'low cost' quadcopters. I wanted to find out from people's experience building quadcopters on the:

A quick question. Has anyone programmed APM for a camera trigger?
Basically, I need to send out +5V when camera must trigger for 250ms and send 0V otherwise.
The problem I have is:
digitalWrite does not seem to work on APM output pins.

I am using APM-1. I am raising this question after I heard from Chris Anderson that SD card interfacing with APM is not possible. It may go a bit technical from here as follows:
I read that SD card interfacing is possible with bit-banging by n

I finally got the solution to the 'frustrating' gimbal lock that I was facing for quite some time with the use of APM board while building my camera mount for a closed loop stabilization. The problem happened on the 2-axis camera mount using P

This is a simple question I am having for some experts out there. I am getting a GIMBAL LOCK problem when I pitch my APM-1 board 90 degrees (downwards), the roll and yaw values becomes crazy.
My current implementation uses ahrs.pitch_sensor

I think I have raised this question quite a few times before, with no answer surprisingly. This is the last time I am giving a shot with this question.
Can I use an external SD card with the APM- 1 board?
If so, how can I use it, do I need to solde
Read more…Hi,
In APM (ArduPlane/ ArduCopter) with/ without Mission Planner, we can observe that when the board is titled down, pitch angle changes from 0 (horizontal position), to 90 (vertically pointing downward), and tilting it further brings/decreases it ba

I was brainstorming on coming up with an idea based on UAV, Quadcopter application in real-time. In the area of surveillance there are many different ideas that can be employed.

I use APM, and I need to do 'drift compensation'. I have the following:
ahrs.pitch, ahrs.roll, ahrs.yaw.
drift vector =( x, y, z )
I use an external Compass for Yaw , and it is enabled. Now, how do I make use of the vectors above; do I need to a

I was interested in doing my master thesis research in the area of UAV. I wanted to know the topics of reseach in the area of building surveillance using a quadcopter.

I have a simple question for experts.
In my gimbal, I am having the PAN/ YAW feature which rotates the gimbal 0-360 degrees, using speed control mechanism. It works, though there seems to be some drift (a.k.a gyro drift, I guess). Here goes my

I am using continuous rotation servo for 'Yaw' control of my camera gimbal. I am using it for stabilization around a setpoint/ target angle, using PID's.
If I give a target of say 60 degrees, the servo should adjust its speed in such a way as

I wanted to learn the difference between AR.Drone platform Vs. APM (used in DIYDrones) platform.
This will also be helpful for all the new folks getting a fair view of the open-source platforms available out there. Just jot in your views..

Can someone guide me what are we doing in the
void AP_Mount::stabilize() .. function of APM exactly? It is part of the libraries that we use for camera stabilization (ArduPLane/ ArduCopter). i.e . libraries/ AP_Mount/ AP_Mount.cpp
There it is
