Hiiiiii everyone,
My gimbal is connected to Ardupilot and I can rotate it by sending MAV_CMD_DO_MOUNT_CONTROL (#205) mavlink message from the ground station.
My problems is that I cannot find a way to get current gimbal angles from the device. I read all the messages come from the ardupilot but it doesn’t contain any information about current gimbal angles.
I suppose it must be MOUNT_ORIENTATION (#265) but I don’t get that message.
Any ideas?

Hello All,
I am looking at the Air Commander GEO Tagging device from Airpixel. Does anyone have any experinece using it. Sounds pretty good. I plan to use it on auto mapping missions on a quad plane with a Sony A6000 camera. I have a seagull and CamRemote, but interested in the AirCommander becuase it writes GEO info directly to the image EXIF data, which streamlines the work flow.
I am interested to read opinoins about it.
Thank you,
David

I’ve been slowly tuning and working on a VTOL tilt rotor plane, updated everything to the latest firmware last week. One issue I’ve had consistently is a bad oscillation on descent trying to land. I upped the motor gain from default 0.5 to 0.75 and it seems to help, but I had a light bulb moment. When the plane is descending nose up, the elevons are responding in the wrong manner. In forward flight elevon down would nose down, but in the “backwards flight” of Tailsitter landing the elevon down motion causes the nose to go up. Has anyone else remedied this? I assume on a non tiltrotor Tailsitter this would be a much bigger issue.

I’m making a first attempt/test at ArduCopter by trying to convert a small quad so far running INAV, rewiring as little as possible in case I want to go back.
However, I cannot get the GPS to work so far (no data), which was already connected and working in INAV, but to a different UART than suggested here: https://ardupilot.org/copter/docs/common-matekf405.html#default-uart-order (I have it on UART 3.)
So my simple question is if it’s necessary to switch GPS to UART 1 to make it work on F405-CTR even though it also says it “can be adjusted to personal preferences”.
Thanks!
EDIT: A second question came up - it looks like I would also have to rewire the motors as per https://ardupilot.org/copter/docs/connect-escs-and-motors.html ?

I am using a pair of Holybro 915MHz SiK telemetry radios to communicate with a Pixhawk 1 in an ArduRover sailboat.
I am experiencing frequent radio dropouts, usually for around 10 seconds at a time. The LEDs on both radio flash until the radios reconnect. The dropouts occur when the radios are right next to each other, as well as at longer ranges. The dropouts seem to be more frequent at longer ranges, but occur even when the signal strength appears perfectly adequate before and after. I have been experiencing this problem since I bought the radios a few weeks ago.
My only explanation at this point is a hardware defect, but I was wondering if there is something I could be missing.
Here is a screenshot of the radio signal log during a run:

Hello! In the flight modes for my Nimbus VTOL (using Pixhawk 2.1), I see “QRTL”. In the “Mission Planning” section using Mission Planner there is only an option to select “RTL” not “QRTL”.
Will RTL and QRTL behave the same if I have QRTL Enabled in my parameters.? Or will the plane just loiter around the home point?
I need to add a RTL to my Mission and have it perform a VTOL landing at the end.
Thanks, Jeff

Dear Community
I am Utkarsh Mishra, currently a 3rd-year undergrad at IIT Roorkee, India. I went through all the pointers and am almost prepared for writing the proposal which I will be sharing soon.
I am very much interested in the walking robot integration project and also have prior experience in legged robotics basically with a bipedal robot. Although, I am aware of the fact that the project is focused on quadrupeds.
I wanted to discuss the expectations that the community has with this integration. As in the project description, the goals seemed just to have a basic legged robot model with static balance and mostly quasi-static balanced movement abilities. Is that so?
Furthermore, it would be great if the simulations can be performed using Gazebo. As the description also talks about procuring a suitable frame, will it include HIL simulations?
I am sorry for such a late response to the community as I was exploring the Arducopter configuration and setup files to get the idea of the working and to plan the implementation of the quadruped. Also as the project description is so brief, it gives rise to immense possibilities. I will be grateful if I get the guidance of what direction to ponder on. @OlivierB @ppoirier

Let’s consider the following scenario:
A UAV has a companion computer (CC) connected via UART. By running mavproxy.py on the CC, is it possible to set the --out parameter to define the IP_ADDRESS/PORT to whom telemetry is redirected. A GCS having that IP_ADDRESS can connect to the CC by initializing the vehicle object using DroneKit. Via the instance vehicle, it is possible to access lots of properties and methods, for example, to check the current battery level or navigate to a certain position.
Let’s suppose the code running on the GCS has to perform some actions based on external triggers. For example, the CC has a camera onboard. When a certain object is recognized, the UAV needs to stop any movement to take a photo or eventually return-to-home
In my understanding, any action performed using a dronekit-python script is running locally on the GCS. If the link is lost, no reaction is possible because the GCS doesn’t know what happened.
This is not ideal because the benefits of having a CC are lost. I assume I’m doing something wrong or I simply forgot to consider some basics.
The goal would be to have a script ABC.py to perform some actions which is located on the UAV. Via GCS only high level instructions should be sent, for example start running ABC.py or stop it.
What is the preferred architecture to accomplish that?
Thanks! Emanuel

Hi all,
I am new to arducopter heli setup and recently installed OmnibusF4V3Pro board on my blade 450 with a flybar.Did maiden yesterday and everything was fine in stabilized mode.I only tested stabilized mode.
So today i tested again and first 3 flights went okay but on my 4th flight in stabilized mode,helicopter started to roll right and it seemed that i had no control to correct it.So after seeing that it was not responding,I moved my cyclic down to avoid hitting it to my fence and it crashed to the ground
I am attaching log.Could anyone please check my log?Thanks.

Using APM 2.6 and AC3.2.1 (coz that’s what I got) to fly a slung cargo to a destination, descend to AGL slightly lower than the length of the sling, and release by servo. Kind of a poor-man’s “package place” mode since this won’t run on AC3.2.
The problem is the copter is not arriving at the intended target altitude, always somewhat lower, and on one occasion (log and waypoints attached) it flew into the ground at the site where it was intended to descend within 3m above the ground. I sense that it was trying to navigate to a waypoint altitude that is “underground”. I cannot completely make sense of the indicated altitude, particularly the GPS alt, with respect to the true elevation.
In each instance, the destination elevation was higher than the home elevation, by from 5m to 25m difference. Not sure if that matters.
I’m sure there’s a simple explanation for this and I’d be so grateful if you would have a look and let me know what I’m doing wrong.
I’ve done many parachute drops, now trying to raise my game for beer and toilet paper delivery by slung-cargo dropoff during COVID lockdown.

Hi and thank you all for sharing your knowledge! Im wondering if there is anyone out there that can help me with my problem. I have been working on a Y6 tiltrotor and i need a little help with the transitional tuning. It uses the firefly6 vtol parameters. Its sort of like a tricopter collided with something in the back of Burt Rutan’s barn. The pixhawk onboard is having a hard time with logs… most of the logs come off corrupt and half the time the sd card does seat properly and it wont arm. i had to bypass logging to get it to arm regularly. I mounted a gopro on the tail so its a pretty good view of whats going on.
here is a picture.
here is a link to the video. https://www.youtube.com/watch?v=GHqM3bVwrJY&feature=youtu.be
here is the parameter file. 2.param (20.8 KB)
The first part of the video is to show how it tilts on the ground when switching from qstabilize to fbwa and then qstabilize to manual. I show both because the speed is different. Then the first transition is almost perfect. all of the next transitions struggle. The very last transition in the video i went from q loiter to fbwa for a few seconds then to manual to get it to switch quickly. the machine weighs about 13 lbs and has plenty of power in all modes. It is a little nose heavy which i intend to fix once dialed in. the motors are lower quality 5208 running on 6s with 18’s on the top and 20’s on the bottom. no air speed sensor, no osd, no ground station or telemetry of any kind. It transitions from plane to hover perfectly every time. from hover to plane is very inconsistent.
The problem that i have is the tilt angle and duration seems to be a little bit different every time. I assume that this is because of airspeed. Sometimes it barely tilts. If anyone has any suggeations let me know. Im not sure if possible but i would like to completely eliminate the need to use airspeed (measured or estimated) during the transition. If i could make it tilt to about 45 degrees and stay there for a certain number of seconds while maintaining multi rotor control, then quickly rotate the other 45 and disable multi rotor control at some adjustable point. I think if i could do that i could dial in a transition that barely looses any altitude during most weather conditions.
Let me know if you have any questions or suggestions. Thanks!!

Dose any one know if single-line encoder (non quadrature) is supported? I use a set of motors for skid steering today and they have a encoder with only one signal cable. When I read the instructions it’s pointing to WENC_PINA and WENC_PINB but I only have one pin that is connected to “AUX OUT 4” for one of the encoders. How do I configure single wire encoders? I’m currently running ArduRover V3.5.1.
