- trajectory_setpoint and vehicle_local_position_setpoint used to be
the same data type
- we got extremely lucky here that this didn't cause any issues due to
all the fields still aligning
Starting the fake position as soon as all the aiding sources stop makes
the local position immediately invalid while we could continue to navigate
for a couple of second with inertial dead-reckoning
- vehicle_imu_status can publish immediately on any measured sample
rate change or sensor error increment, but the windowed mean/variance
shouldn't necessarily reset that often
This is to prevent that that data from non-recent publications of the virtual
attitude setpoints are used in the transition code.
It removes the previous implementation where the update_transition_state()
method was only run when both mc and fw virtual att sp where recent, independetly
of whether both are used or not.

The function is now only available with an int as the argument.
- Previously it was hard to check which state the gripper was in
(GRAB/GRABBED/ etc), not even whether it was correctly initialized, this
commit adds that functionality
- When the gripper was uninitialized, the error message popped up
everytime the module had 'any' vehicle command received. But we should
be spamming only when we do actually get 'DO_GRIPPER' command received,
this commit adds that feature
- Also converted error messages for CLI when gripper test functinality
fails, so that user would get a feedback (originally, the PX4_DEBUG was
of course not outputting everything)
Also containst a mini refactor by removing the unnecessary function
get_default_altitude_acceptance_radius().

This new check is inteded to trigger if there is no data variation published by
the airspeed driver for the first 10s after the first data is published.
This is to capture malfunctioning sensors/drivers that do publish a value, this
value though does not come from real sensor measurements.
Previously this was captured by the data stuck check, but it has shown that
some drivers can publish a stuck value without being actually malfunctioning
(e.g. when the airspeed is outside of their measurement range). Checking for
any data variation is the more conservative check that still catches the above
described failure case.

If the current yaw setpoint is valid we should use it to make the transition in this direction.
For a VTOL_TAKEOFF the yaw_setpoint is used to specify the transition direction (the
vehicle is aligned towards it and then transition is started). The current yaw can be
a bit off (e.g. because MIS_YAW_ERR is large), and it is better to track the actual setpoint.

As I understand it, only Rev 3 and Rev 4 were shipped by HB for Mini and
CM4, and are likely to be used for it.
It would be nice to have all combinations but it requires quite some
flash in the current implementation.
For targets that define the SPI buses via px4_spi_buses_all_hw, a call
to px4_set_spi_buses_from_hw_version() is needed. Otherwise a NULL

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

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
When hitting zero thrust by stick there is 0 torque authority
without airmode. So 0% minimum manual thrust should never be the default
without airmode.
Uses COM_SPOOLUP_TIME to slowly ramp the throttle and allow the
tailrotor to compensate in a coordinated way based on the yaw
compesation from throttle, see CA_HELI_YAW_TH_S.
This coordinated spoolup is necessary to avoid unsafe yaw twitches
because of the heli rotating until the correct compensation kicks in
through the feedback controller.
Move logic implemented in the header files to source files, this way
it will be simpler to define which is compiled to kernel space and
which to user space
Also allows to remove some headers that pull in half the universe
from the board definitions (which should just be pin definitions and
no functionality)
Fixes the compile error on llvm:
mixture of designated and non-designated initializers in the same initializer list is a C99 extension [-Wc99-designator]
- a growing number of samples come into the backend with the time
already delayed (sensor's interrupt setting timestamp sample)
- if the incoming timestamp is already delayed then the new data checks
(relative to latest IMU) can be slightly wrong
- handle almost all timestamps and checks on delayed time horizon,
except for explicit checks of new samples
- isRecent() and isTimedOut() helpers use delayed time
- add new isNewestSampleRecent() used for checking the incoming
timestamp of the incoming (adjusted) data
- print list of events whenever they change if
CONSOLE_PRINT_ARMING_CHECK_EVENT is set, instead of on each update call
- reduce flash usage by moving out templated code into non-template method
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)
Also remove the legacy "range aid" than can be achieved by setting the
height reference to range finder and the range finder control parameter
to "conditional".
Conditional range aiding cal also be set when the height reference isn't
the range finder. This prevents the ratchetting effect due to switching
between references.
Instead of having a single height source fused into the EKF and the
other ones "waiting" for a failure or the primary sensor, fuse all
sources in EKF2 at the same time. To prevent the sources from fighting against each
other, the "primary" source is set as reference and the other ones are
running a bias estimator in order to make all the secondary height
sources converge to the primary one.
If the reference isn't available, another one is automatically selected
from a priority list. This secondary reference keeps its current bias
estimate but stops updating it in order to be the new reference as close
as possible to the primary one.
- 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)

Since the horizontal and vertical velocity controllers are now
decoupled, it can be that the horizontal acceleration produced by the
controller is actually greater than the desired one (by design). This
condition would actually make the ARW run "backwards", degrading the
controller performance.
Directly use yaw controls for it, and don't add it to the allocation matrix,
as that would have an effect on rudder scaling if the wheel also would have
a yaw effectiveness.

2fbb70d9ca made the lowest possible
throttle value commanded by stick in Stabilized mode before taking off 0.
The real world problem with this is that when takeoff is detected then
the entire throttle scaling range jumps from
[0, MPC_MANTHR_MIN]
to [MPC_MANTHR_MIN, MPC_MANTHR_MIN].
As a result whenever MPC_MANTHR_MIN is not zero there is a thrust jump
on every takeoff just at the moment takeoff is detected even when the
stick is moved continuously.
Because of this I suggest to revert to having a higher throttle value
from the beginning on because it's less complicated and there's
no obvious value in starting out with zero thrust if anyways not
possible to go back to zero for safety once takeoff is detected.
Using the control status flags isn't robust as this part of the code
runs at the EKF update rate while the in_air transition is don at the
prediction rate. It was then likely to miss the transition
