UAV not responding to keyboard controls

[shubham-shahh]

Hi,
when I run the keyboard node there are no errors and the props start spinning in gazebo simulation, but when I use "1" it doesn't take off, nor do other commands work. there are no error messages as well. @Boyang--Li @Ttoto

Can you see the "takeoff" in your terminal？
If so, Would you please have a check of the MAVROS messages (Topic name: /mavros/setpoint_position/local)?

Hi,
when I launch the keyboard node, the output in the terminal is

I am using ROS Noetic @Ttoto

before starting the keyboard node, the "./sim.sh" terminal outputs

It seemed everything is workout fine. Would u please have a check of ur PX4's version?

It is the same, as mentioned in the Repo instructions, I think the UAV is not able to localize hence it is constantly asking for Home position, there must be some problem with GPS, any fix for that?

[Ttoto]

So what u mean is that the position information(FLVIS or GPS) is not fixed and the vehicle is unable to arm and take-off?

I think the position output for x and y should not be 0. It may be caused by you are not correctly using the positioning message from GPS or the FLVIS (VIO). You can check the configuration of the PX4 parameters via QGroundController or other Apps. Also, you can try to put this package into a NEW workspace to eliminate any interference.
