The flightControl sample code of the ROS platform reports an error: Takeoff failed. Motors are not spinning.

Keywords: ROS flight control, flightCtrl, takeoff failed

Troubleshooting steps:

1. Confirm the take-off status of the drone (check with RC and APP), that is, whether the drone has taken off(on simulator);
2. Test the sample code with the Linux platform. If the sample code of the Linux platform is normal but the ROS is abnormal, it is recommended to check the ROS baud rate. ROS recommends using a baud rate of 921600 and above
