    Hello Everyone! Im trying to use precision landing with IRlock in RTL mode but it never uses it!

    IRlock works in precision loiter and in land but RTL does not work at all.

    The setup is a quadcopter with the latest version of arducopter.

    Anyone knows how to make RTL look for IRLock and use it for landing?

    Apparently terrain follow has to be enabled , but it limits you to have the rtl alt to the rangefinder maximum alt

    Hi All,

    I’m looking for roslaunch files for global planner and local planner px4 obstacle avoidance running intel realsense D435 on a real drone not in simulation.

    I will appreciate any thing you are able to provide because I’ve been hacking away at this for weeks and it’s the standard supported configuration in the obstacle avoidance project so it shouldn’t be difficult for somebody who has tested it or used it to just send me what you have so I can look it over and compare it with what I’m having.
    I think it’ll be a lot easier if I can just see what works and then adapt my files to that.

    I will very much appreciate your help.

    Sincerely,

    Aaron

    Hi guys, I have problem when using vicon system.
    When I use vicon as mav gps for my drone, the drone can not hovering, it drift instead.
    I already checked the orientation and it seem be true with respect to the NED frame.
    When I add the optical flow, the drone can hovering pretty good.
    So I think there might be have some problem with my vicon setup but I don't know which is problem.
    Can anyone help me with this? Thanks!

    Hi All,
    I am facing an issue with setpoint velocity/position in guided mode. I am using Cubeorange with arducopter 4.0.5, running mavros on a companion computer connected via usb on the fcu. I am using a slam system to give pose data(not using gps as it's for indoor flight) to the drone, and the message is being received by the fcu (i can see the message in mavlink inspector). After this, when i switch to guided mode and give it a setpoint velocity/position message from mavros, i don't see any movement from the drone, and it often just starts drifting randomly (in random directions). I don't know what logs to share that show i am sending setpoint velocity and it is not being used by the fcu, but if anyone can suggest anything i can share those logs. I have also tried doing the same out in the open with gps (and no slam) and i see similar behavior. At this point i have no idea how to debug this issue. I must also add that i have worked with similar setup in the past and have had no issue like this and really lost about what could cause this. Any help with this would be appreciated. Thanks.

    Hey everyone, I've been playing around with mavros to interface a NVIDIA Jetson Nano and a Pixhawk through the GPIO to/from telemetry port. I'm launching mavros with the apm launch file.
    I'm able to arm/disarm successfully and although in a peculiar way, I'm also able to change to custom modes.
    So although I'm able to change modes with the command, for instance:
    rosrun mavros mavsys mode -c 1
    I still get an error " CMD: Unexpected command 11, result 0". But it does change the mode nevertheless (I can see it in Mission Planner)

    Although if I issue:
    rosrun mavros mavcmd int 176 0 1 0 0 0 0 0
    I get the error " CMD: Unexpected command 176, result 3"

    Shouldn't mavsys mode -c 1 use command 176?

    The other thing I've been trying to do is to test actuating on a servo, which should work by using MAV_CMD_DO_SET_SERVO, (command 183), although once again after issuing:
    rosrun mavros mavcmd int 183 1 1023 0 0 0 0 0
    I'm getting the error "CMD: Unexpected command 183, result 3"

    It's probably something really basic... but I can't put my finger on it.
    Any pointers?

    I think you need to post on ardupilot’s discord channel - vision project

    @cjmv
    Hi @juvinski , who me? I have no problem on doing that. But what does that mean exactly? Does that mean that I will probably get better help on Discord than here? :-)
    Jaime Machuca
    @jmachuca77
    Yes the Gitter channels have been deprecated for a while new discussions should be done on discord
    Carlos Vicente
    @cjmv
    Hi @jmachuca77 , Thanks... will do then!
    Carlos Vicente
    @cjmv
    By the way... I'm looking for it on Discord but I can't see to find it in the Public Servers. What's the actual name of it?

    Hey guys, I am planning to implement obstacle_distance plugin in mavros. i have created a separate script to reduce laser data points to 72 but when i run this script i get this error on roslaunch mavros terminal:

    Am i supposed to add obstacle_distance config under apm_config.yaml? if yes, what should it contain?I really appreciate if someone could help me. Thank you

    Hi Guys,
    I'd like to ask for help with mode changing of ardurover with mavros.
    Here is my situation:
    I am using Ardurover for floating drone and working on anticollision system.
    I am trying to send mavlink commands via mavros to ardupilot rover.
    mavsafety arm/disarm is working fine, but I can’t change mode of the autopilot.
    I am sending message with: rosrun mavros mavsys mode -c HOLD
    I am getting response: Error:Unsupported FCU
    I run out of ideas how to solve this. Any idea of what might be the issue?
    Any help appreciated.

    All the best!

    Hello,

    I'm working on a multi-copter project that will follow a Aruco target. The goal is to "land" in a kind of net on a sailing boat using a comanion computer
    I need a precision about 50cm in XYZ.

    I tried :

    • Precision landing, but when the camera loose the Aruco, the drone still continue the landing process
    • control attitude in Guided no gps mode, but it's a little bit complex as I need to filter aruco position, implements PID for attitude target...
    • Vision Positionning, but I can't send vision positionning messages all the time because camera shows the aruco only at the end of the flight... And I've a doubt about it also because in this case, the reference is moving then I 'm not sure how the drone will act if I tell it it's moving and its IMU says it doesn't? I tried what is explain here (https://ardupilot.org/copter/docs/common-non-gps-to-gps.html) but I got an error message at init "Vision Position not healthy"

    My question is what is the better way to implement that for you? Any other ideas?

    @Dronotique can you join discord server, we have moved away from Gitter. I have a PR in the pipeline that "retires" landing incase the camera looses the target, and it also gives you an option to not land at all incase the target isn't in sight. ArduPilot/ardupilot#17930
