Hello,
The former wiki for Ardurover was complete and clear about the first time setup. The current new ardurover wiki site does not give a clue about the channel assignments In (steering, throttle, mode)/Out (which servo outputs to use for steering/t

I would like to test a real antenna tracker, driven by a Pixhawk and the antenna tracker firmware, which is setup "in the middle" : on one side the antenna tracker is linked via 3DR radio to the vehicle, on the other side, it is linked to a PC

We did a XAUV Talon flight with latest Arduplane release.
The flight started fine in auto take off with a catapult method.
Once in flight the plane started to make a sinusoidal trajectory as if the center of gravity was off, although the CG had been

First the VIBE graph : I see Z-accel seems quite high (and in the classical vibration graph, it goes from +5 to -5

If 3DR really stops the radios, what could be reliable repl

Hi,
The EPO foam hinges are weak : repetitive mechanical movements of the surfaces end up breaking the very thin EPO foam fixing them.
Here a video of a crash we had because of the loss of the left aileron in mid flight at 30 m altitude, and how I made

In the never ending quest to improve camera triggering via Pixhawk, one of my objective was to reduce as much as possible the triggering latency. That is the time between the moment the autopilot processes a trigger instruction (sent out on a pred

I posted this on drone-discuss but without any answer, so I try here again:
In an objective to georeference images, I'd like to export from a .bin log file the CAM & GPS messages with corresponding timestamps (the time that is d
I flew this summer repeatedly with my X8 setup with two GPS : a 3DR LEA6H and a M8N-XL (Drotek):
Browsing though the log files I was amazed how better the M8N-XL performed vs the smaller 3DR LEA6H. I selected random one of those flight logs to show

I share hereunder what worked for me to get a succesfully working dronekit python on windows; I indeed could not have anything work with the so-called windows installer (an .exe file that is supposed to install everything automatically on your win

I wanted to download the dronekit api (windows installer) from http://python.dronekit.io/guide/getting_started.html, but the link is broken. Anyone could upload it to share ?

I do not knwow if I did not sleep well but can't find manual mode anymore (3.2.1). Tried on two different mission planner on two computers.
Without manual mode it is impossible to calibrate the current measurement as it is the only mode where the t

During a quadcopter autotune which started very good, I had passed the roll tuning phase and the quad was in the middle of the pitch tuning phase. I recentered the quad a few times. Until I had apparently the bad idea of correcting slightly the ya

Hi,
During our last training session where we tried "Auto-Take off" (@1:25 min in the video) with the last Arduplane 3.3 version, I noticed a severe drop at the exit of the catapult. We tried to the minacc (was at 4m/s) , minspd (15m/s) and throttle d

I 've got an issue on an octo build : an explained drift in loiter mode (seems to the right each time but could have been the Wind at that moment). Stabilize is fine.
I've looked in the log and I see a discrepancy between X, Y velocities and Desi

I'm looking for the MAV_TYPE values of all the pixhawk parameters. I just could find the list of parameters on the wiki doc, but could find nowhere what is the MAV_TYPE value of each.
For example : what is the MAV_TYPE value of the parameter "CIRCL

What is the signal's logic voltage level on pixhawk I2C and GPS port? 3.3V or 5V?
I do not have an oscilloscope so if someone had the answer, it would spare me to buy this equipment :)
Thx
