New follow-me flight task 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 mavsdk: cosmetics :lipstick:
