landing airspeed was previously defined by a scale factor multiplied by minimum airspeed. this commit changes this parameter to an explicit speed, and when unspecified, defaults to the minimum airspeed
MIS_LTRMIN_ALt was used to limit the go-to altitude of a LOITER_TO_ALT (not the exit altitude,
but the altitude that the vehicle went to to fly to WP), and during landing abort to climb to
at least this altitude. The min entry altitude of LOITER_TO_ALT I remove with this commit, while
for the min alt during abort I added the new parameter MIS_LND_ABRT_ALT.

* Enable motor controls for fixed wing mode in tailsitters
This commit enable motor controls in fixed wing mode for tailsitters
This is needed for enabling quad tailsitters
* VTOL: differential thrust in FW: adapt params to be generic for all axes
Until now only suppoted on yaw axis. Not to be supported also on Roll and Pitch.
- VT_FW_DIFTHR_EN: make bitmask for all three axes independently. First bit is Yaw,
sucht that existing meaning of VT_FW_DIFTHR_EN doesn't change.
- VT_FW_DIFTHR_SC: rename to VT_FW_DIFTHR_S_Y and add same params for roll (_R) and
pitch (_P).

- update all msgs to be directly compatible with ROS2
- microdds_client improvements
- timesync
- reduced code size
- add to most default builds if we can afford it
- lots of other little changes
- purge fastrtps (I tried to save this multiple times, but kept hitting roadblocks)
* Changed sitl_gazebo to the advanced liftdrag plugin fork.
* Added advanced plane and its associated parameters to PX4. Also tweaked one of the plugins to fix a compilation error (upcasting from float to double).
* Switched gazebo back to main branch, to avoid merge conflicts.
* Change simulator bridge back to what it was in main branch
* Changed sitl_gazebo to match the PX4 main branch's (commit hash b968405)
* Changed SimulatorIgnitionBridge to match most recent main.
- for convenience merge px4_sitl_ign into px4_sitl_default, but allow simulator_ignition_bridge to quietly skip inclusion if ignition-transport isn't available
- simulator_ignition_bridge only try setting the system clock in
lockstep builds
- this simplifies usage and CI system dependencies
- rcS parameter backup try to directly restore param (FRAM) from backup (in case SD card is removed before successful export)
- rcS parameter backup logging rearrange to capture more logging output (param_import_fail.txt)
- posix rcS try to keep param backup and restore roughly in sync with NuttX rcS
- tinybson fix debug printf format
- param_export_internal ensure file descriptor positioned at 0 (precaution)
This feature allows user to use a Gripper type pacakge delivery
mechanism on a drone to trigger the delivery during a mission via the
mission item `DO_GRIPPER`.
This is a minimal change that is intended to have simplest pacakge
delivery feature on PX4, however the future scope would extend this
feature out of Navigator, and rather move towards a federated PX4
(flight-mode flexibility) architecture. But until then, this will serve
the purpose.
Update Tools/sitl_gazebo submodule to remove sdf file overwrite error
- There was an error happening due to .sdf file being overwritten, it
was caused by a wrongfully added. sdf file.
- This update pulls in the PR commit: https://github.com/Auterion/sitl_gazebo/pull/147
Initial cut on supporing PAYLOAD_PLACE mission item
Tidy and comment on navigation.h to clarify mission item definition
- Convert vehicle command ack subscription data type to
SubscriptionData, to not care about having a dedicated struct for
copying the latest data
- Tidy and comment on navigation.h to clarify the definition of
mission_item_s, which is confusing as it is an intergration of MAVLink
Standard into PX4's internal Mission Item structure
Rename mission_block's mission item reached function & cleanup navigator
- Isolated Handle Vehicle Commands function inside the Navigator
- Rename mission_block's mission item reached function to 'reached or
completed', as the navigation command can also be an action (e.g.
DO_SET_SERVO, which doesn't make sense to refer to as 'reached' when we
have successfully done executed the command)
Include MAVLink PR commit to include payload_drop message
More changes to add payload_drop MAVLink message support
- Comitting for testing purposes
Add mission item payload_drop to vehicle command payload drop link
- Now with a mission item with the nav_cmd set to 'payload drop', the
appropriate 'payload drop' vehicle command will be issued
Make Payload drop executable via Mission Plan
Implement payload_drop module to simulate payload delivery
- Simple module that acknowledges the payload drop vehicle command after
certain time, to simulate a successful delivery
Additional changes - payload drop module not working yet
- Need to do more thread stuff to make it work :(
Fix Payload Drop enum mismatch in vehicle_command enums
- First functional Payload Drop Implementation MVP
- Simple Ack & resuming mission from Navigator tested successfully
Hold the position while executing payload drop mission item
- Still the position hold is not solid, maybe I am missing something in
the position setpoint part and all the internal implications of
Navigator :(
Add DO_WINCH command support
Some fixes after rebase on develop branch
- Some missed brackets
- Some comment edits, etc
Add DO_WINCH command support
- Still has a problem of flying away from the waypoint while the
DO_WINCH is being executed, probably position setpoint related stuff :(
Apply braking of the vehicle for DO_WINCH command
- Copies the behavior of NAV_CMD_DELAY, which executes a smooth, braking
behavior when executing the delay because of the braking condition in
`set_mission_items` function
- This will not apply to Fixed wings
- The payload deploy getting triggered may be too early, as right now as
soon as the vehicle approaches the waypoint within the acceptance
threshold, the payload gets deployed
Add DO_GRIPPER support
Implement Gripper actual Hardware triggering support
- Currently not working, possibly in the mixer there's a bug
- Implemented the publishing of actuator_controls_1 uORB topic
- Implemented the test command for the payload_drop module, to test the
grpiper functionality
- Edited px4board file to include the payload_drop module
- Added Holybro X500 V2 airframe file, to enable testing on X500 V2
- Created new Quad X Payload Delivery mixer, which maps the actuator
controls 1 topic's data into the MAIN pin 5 output
Make Payload Drop Gripper Work
- Initialization of the Gripper position to CLOSED on Constructor of the
payload_drop module
- Setting the OPEN and CLOSED value to the appropriate actuator controls
input
Set vehicle_command_ack message's timestamp correctly
- By not setting the timestamp, the ack commands were not correctly
graphed in PlotJuggler!
Rename payload drop module to payload deliverer
- I think it's a more complex name (harder to type), but more generic
Add Gripper class (WIP)
Add Gripper class functionalities
- Add gripper uORB message
- Add gripper state machine
Use Gripper class as main interface in payload_deliverer
- Utilizes Gripper class functions for doing Gripper functionality
Remove mixer based package delivery trigger logic
- Remove custom mixer files that mapped actuator controls to outputs
statically
Additional improvements of the payload_deliverer
Fix payload_deliverer module not starting
- _task_id wasn't geting set appropriately in task_spawn function, which
led to runtime failure
Add Gripper Function to mixer_module
- Still not showing up as function mapping in QGC, needs fix
Add parameters to control gripper behavior
- Now user can enable / disable gripper
- Also select which type of gripper to use
Applying review from nuno
Remove timeout fetching from mission item and use gripper's timeout
- Previously, it was planned to use a custom DO_GRIPPER and DO_WINCH
MAVLink message definitions with information on timeout, but since now
we are using original message definition, only relevant timeout
information is defined in the payload_deliverer class
- This change brings in the timeout parameter to the Navigator, which
then sets the timeout in the mission_block class level, which then
processes the timeout logic
Make payload deployment work for Allmend test :P
Support gripper open/close test commands in payload_deliverer
Move enum definition for GRIPPER_ACTION to vehicle_command.msg
Remove double call for ` ${R}etc/init.d/rc.vehicle_setup`
- Was introduced during the rebase
- Was causing module already running & uORB topic can't be advertised
errors
Fix format via `make format` command
Modify S500 airframe file to use for control allocation usage
- Added Control allocation related parameters as default to not have it
reset every time the airframe is selected
Implement mission specific payload deploy timeout and more changes
Switch payload_deliverer to run on work queue
Remove unnecessary files
- Airframe changes from enabling control allocation are removed
Address review comments
- Remove debug messages
- Remove unnecessary or verbose comments & code
- Properly call parameter_update() function
Switch payload_deliverer to scheduled interval work item & refactor
- Switch to Schedeuled on Interval Work Item, as previous vehicle
command subscription callback based behavior led to vehicle comamnd ack
not being sent accordingly (since the Run() wouldn't be called unless
there's a new vehicle command), leading to ack command not being sent
out
- Also, old vehicle commands were getting fetched due to the
subscription callback as well, which was removed with this patch
- Fix the wrong population of floating point param2 field of vehicle
command by int8_t type gripper action by creating dedicated function
- Refactor and add comments to increase readability
Add gripper::grabbing() method and handle this in parameter update
- Previously, the intermediate state 'grabbing' was not considered, and
when the parameter update was called after the first initialization of
the gripper, the grab() function was being called again, which would
produce unnecessary duplicate vehicle command.
- Also replaced direct .grab() access to sending vehicle comamnd, which
unifies the gripper actuation mechanism through vehicle commands.
Navigator: Change SubscriptionData to Subscription to reduce memory usage
- Also removed unused vehicle command ack sub
PayloadDeliverer: Remove unnecessary changes & Bring back vehicle_command sub cb
For SITL it's important that the GCS receives the first events messages
that reset the sequence number, in case the user does not press 'Disconnect'
when restarting SITL.
- new modules/simulation directory to collect all simulators and related modules
- new Tools/simulation directory to collect and organize scattered simulation submodules, scripts, etc
- simulation module renamed to simulator_mavlink
- sih renamed to simulator_sih (not a great name, but I wanted to be clear it was a simulator)
- ignition_simulator renamed to simulator_ignition_bridge
- large sitl_target.cmake split by simulation option and in some cases pushed to appropriate modules
- sitl targets broken down to what's actually available (eg jmavsim only has 1 model and 1 world)
- new Gazebo consistently referred to as Ignition for now (probably the least confusing thing until we fully drop Gazebo classic support someday)
- much simpler direct interface using Ignition Transport
- in tree models and worlds
- control allocation output configuration, no more magic actuator mapping to mavlink and back
- currently requires no custom Gazebo plugins (keeping things as lightweight and simple as possible)

- landing slope/curve library removed
- flare curve removed (the position setpoints will not be tracked during a flare, and were being ignored by open-loop maneuvers anyway)
- flare curve replaced by simply commanding a constant glide slope to the ground from the approach entrance, and commanding a sink rate once below flaring alt
- flare is now time-to-touchdown -based to account for differing descent rates (e.g. due to wind)
- flare pitch limits and height rate commands are ramped in from the previous iteration's values at flare onset to avoid jumpy commands
- TECS controls all aspects of the auto landing airspeed and altitude/height rate, and is only constrained by pitch and throttle limits (lessening unintuitive open loop manuever overrides)
- throttle is killed on flare
- flare is the singular point of no return during landing
- lateral manual nudging of the touchdown point is configurable via parameter, allowing the operator to nudge (via remote) either the touchdown point itself (adjusting approach vector) or shifting the entire approach path to the left or right. this helps when GCS map or GNSS uncertainties set the aircraft on a slightly offset approach"
- all sources of optical flow publish sensor_optical_flow
- sensor_optical_flow is aggregated by the sensors module, aligned with integrated gyro, and published as vehicle_optical_flow
