* This fix is necessary because usually uORB structs get initialized with
all zeros and then get filled with the fields that are actually in use.
* The number 0 for the mode slot was already commanding to switch to the
mode in slot one even though for example the joystick input via mavlink
does not use this mechanism at all.
This commit adds Roll Pitch Yawrate Thrust (RPYrT) setpoint control to the
PX4 stack, enabling the UAV to follow specific yawrates sent from
offboard. It also introduces individual body_rate flags, along the
lines of mavros.
Tested on a MoCap enabled flight arena in KTH Royal Institute of
Technology, Stockholm. The MAV receives RPYrT setpoints from an
external PID controller to stabilize around position setpoints.
The UAV is also externally disturbed to assess the stability to
external unmodeled events.
Fixed Kabir comments.
Removed deprecated ignore_bodyrate.
Fixed integration test.
The initial idea of the flight task architecture was that
a task can freely set it's setpoints and doesn't have to
worry about takeoff and landing. It would just takeoff
when it's landed and there's a setpoint to go up and
land when it puts a setpoint that pushes into the ground.
With the takeoff logic there are some significant interface
problems depending on the way a task is implemented:
From the setpoint is not high enough to trigger to
an unexpected takeoff because of some estimator
fluctuation affecting the setpoint. It's easiest to solve this
by allowing the task to determine when a takeoff is triggered.
If no condition is implemented by default a task is not
allowing a takeoff and cannot be used to get the vehicle
off the ground.
This allows to perform pre-arm checks and prevent arming if obstacle avoidance is enabled but not yet running.
Added a print once flag to prevent excessive message spamming in QGC.
