MAVSDK-Python: action.do_orbit no attribut found error message.
Hi, I am trying to achieve an auto mission with do_orbit function to move the drone in circle facing towards alawys front option. I tried using mavsdk python and it gives the following error.
`Error msg:
Waiting for drone to connect…
Drone discovered!
Waiting for drone to have a global position estimate…
– Global position estimate OK
– Arming
— Taking Off

@arpitpara it would be great if you could add an example to https://github.com/mavlink/MAVSDK-Python/tree/main/examples once you have something that nicely works against SITL.
so…analyzing this ulg file with plotjuggler: The drone was for ~10 seconds in ORBIT mode. The navigation mode is written in the
vehicle_statusuORB topic in the fieldnav_state. As you can see, it’s 21 for around 10 seconds and checking https://github.com/PX4/PX4-Autopilot/blob/main/msg/VehicleStatus.msg you will findNAVIGATION_STATE_ORBIT = 21.The issue seems that the takeoff didn’t have enough time to do it’s job: the drone reached only 0.5m altitude. Then you gave him the orbit command to orbit somewhere at 2.5m AMSL, even though your flight started at ~488m AMSL.
So my tip: Use
float("nan")for param7/altitude to use the current vehicle altitude (see https://mavlink.io/en/messages/common.html#MAV_CMD_DO_ORBIT) and give all the sleeps a little bit more time, especially the takeoff. Or consider a way of checking whether the drone finished takeoff before sending the orbit command. Eventually, the land detector detected the drone touching the earth and caused the drone to disarm.Edit: the altitude graph:
Sorry for pasting the whole code. But there was no error shown. That’s why
I think you are supposed to use the enum instead of raw integers, e.g.
