Fix Follow Perspective Param metadata
follow-me: use new trajectory_setpoint msg
Convert FollowPerspective enum into a Follow Angle float value
1. Increases flexibility in user's side, to set any arbitrary follow
angle [deg]
2. Removes the need to have a dedicated Enum, which can be a hassle to
make it match MAVSDK's side
3. A step in the direction of adding a proper Follow Mode (Perspective)
mode support, where we can support kite mode (drone behaves as if it is
hovering & getting dragged by the target with a leash) or a constant
orbit angle mode (Drone always on the East / North / etc. side, for
cinematic shots)
Continue fixing Follow Target MAVSDK code to match MAVSDK changes
- Support Follow Angle configuration instead of Follow Direction
- Change follow position tolerance logic to use the follow angle
*Still work in progress!
Update Follow Me MAVSDK Test Code to match MAVSDK v2 spec
- Add RC Adjustment Test case
- Change follow direction logic to follow angle based logic completely
- Cleanup on variable names and comment on code
follow-me: disable SITL test
Need to update MAVSDK with the following PR:
https://github.com/mavlink/MAVSDK/pull/1770
SITL is failing now because the follow-me
perspectives are no longer defined the
same way in MAVSDK and in the flight task.
update copyright year
follow-me: mark uORB topics optional
Apply review comments
more copyright years
follow-me sitl test: simpler "state machine"
flight_mode_manager: exclude AutoFollowTarget and Orbit on flash contrained boards
Remove unnecessary follow_target_status message properties
- As it eats up FLASH and consumes uLog bandwidth
rename follow_me_status to follow_target_status
enable follow_target_estimator on skynode
implement the responsiveness parameter:
The responsiveness parameter should behave similarly to the previous
follow-me implementation in navigator. The difference here is that
there are now two separate gains for position and velocity fusion.
The previous implemenation in navigator had no velocity fusion.
Allow follow-me to be flown without RC
SITL tests for follow-me flight task
This includes:
- Testing the setting for the follow-me angle
- Testing that streaming position only or position
and velocity measurements both work
- Testing that RC override works
Most of these tests are done with a simulated model
of a point object that moves on a straight line. So
nothing too spectacular. But it makes the test checks
much easier.
Since the estimator for the target actually checks new
measurements and compares them to old ones, I also added
random gausian noise to the measurements with a fixed seed
for deterministic randomness. So repeated runs produce
exactly the same results over and over.
Half of the angles are still missing in MAVSDK. Need to create
an upstream PR to add center left/right and rear left/right options.
These and the corresponding SITL tests need to be implemented
later.
sitl: Increase position tolerance during follow-me
Astro seems to barely exceed the current tolerance (4.3 !< 4.0)
causing CI to fail. The point of the CI test is not to check
the accuracy of the flight behaviour, but only the fact that the
drone is doing the expected thing. So the exact value of this
tolerance is not really important.
follow-me: gimbal control in follow-me
follow-me: create sub-routines in flight task class
follow-me: use ground-dist for emergency ascent
dist_bottom is only defined when a ground facing distance sensor exist.
It's therefore better to use dist_ground instead, which has the distance
to the home altitude if no distance sensor is available.
As a consequence it will only be possible to use follow-me in a valley
when the drone has a distance sensor.
follow-me: point gimbal to the ground in 2D mode
follow-me: another fuzzy msg handling for the estimator
follow-me: bugfix in acceleration saturation limit
follow-me: parameter for filter delay compensation
mantis: dont use flow for terrain estimation
follow-me: default responsiveness 0.5 -> 0.1
0.5 is way too jerky in real and simulated tests.
flight_task: clarify comments for bottom distance
follow-me: minor comment improvement
follow-me: [debug] log emergency_ascent
follow-me: [debug] log gimbal pitch
follow-me: [debug] status values for follow-me estimator
follow-me: setting for gimbal tracking mode
follow-me: release gimbal control at destruction

Symmetric buffers allow a much more reliable QGC Wifi telemetry connection especially when (virtual) joysticks are used. (this board does not provide RX DMA on UART 4 as its timer does DSHOT).
The noise spectral density, NSD, (square root of power spectral density) is a
continuous-time parameter that makes the tuning independent from the EKF
prediction rate.
NSD corresponds to the rate at which the state uncertainty increases
when no measurements are fused into the filter.
Given that the current prediction rate of EKF2 is 100Hz, the
same tuning is obtained by dividing the std_dev legacy parameter by 10:
nsd = sqrt(std_dev^2 / 100Hz)
The noise spectral density, NSD, (square root of power spectral density) is a
continuous-time parameter that makes the tuning independent from the EKF
prediction rate.
NSD corresponds to the rate at which the state uncertainty increases
when no measurements are fused into the filter.
Given that the current prediction rate of the wind estimator is 1Hz, the
same tuning is obtained with the same values as before.
1. Rename *_header_s structs to *_s, since the _header postfix is not
helpful
2. Rename the "key" string variables in the message structs to
"key_value_str" as the string actually contains not just the key but the
key and value pair information
3. Add comments on other uLog messages to clarify use (need more
improvement / can be even more simplified)
