actual flight

[LizhichengDlut]

Hi, Keipour I met some questions when I made the real experiment. I used Pixrecer R15 hardware, and upload FMUv4 firmware as following the PX4 user guide, After this, i try to make the fully-actuated UAV take off, but When I pushed the throttle lever to the maximum using the remote control, the fully-actuated hexacopter still couldn't take off. So I dare not switch the flight mode to offboard, have you encountered this situation again?

I used to use a regular Mavros interface, which can also be used in simulation environments. I see this interface in github readme, is it necessary when I use ROS for offboard flight? How should i use this？

Hello @LizhichengDlut, it has been some time since I have left the project and @mmousaei might be a better help. We have seen a behavior where the rotors just rotate with the idle speed no matter what input is provided when other firmwares/hardwares are being used (other than Pixracer), which should be easy to fix but we never needed it and never tracked down the issue to fix the bug; but Pixracer should be compatible (unless if something has drastically changed from R14 to R15) and you should not be seeing that behavior. Flying with the remote controller should be independent from MAVROS and it should take off regardless when using the remote. We have not tested with the regular MAVROS, so cannot tell if that is compatible or not. I would suggest using the software developed with this firmware as explained in the README. Hope that helps.

Thanks for your reply, it might be much helpful How is the inclination direction of a drone set, that is, the rotation direction and position of each rotor, as well as its inclination direction and corresponding channel number, are there corresponding file descriptions? Hope reply soon

Thanks，I find it , the first rotor is channel 1? right?
