* 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 fixes the terrifying case where the drone disarms in-air just
because it receives a MAVLink disarm command. We now check param2 for a
magic number which enforces arming/disarming.
This is added to the mavlink protocol in:
https://github.com/mavlink/mavlink/pull/1162
It doesn't affect fixed wing flying anymore. I disabled it for the
deltaquad since I presume @sanderux prefers to have the feature disabled
even when flying in multicopter mode.
AAs discussed in the devcall this functionality is only useful for
rotary-wing (multicopter) flying since it's a big safety hazard to
accidentally bring a fixed wing out of an auto mode e.g. a mission
and fly away in a straight line or into an obstacle.
This param has no effect within the Firmware.
The param can be used for example:
* in log post processing to have context about the flight
* in ground stations to adapt the UI automatically
outside the fence" to "engage geofence failsafe on transition". This
way, the pilot is not stucked in the non flight zone and can switch to
a manual mode and fly back or trigger RTL.
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.
This moves the hysteresis test out of the systemlib and makes it its own
small library. Since it still depends on hrt_absolute_time this does not
link yet. My attempt to get all link dependencies together failed.
