This allows you to arm the copter without any extra GCS commands while
in auto, and can be done from both the GCS, or the RC Tx. This is useful
for creating a simpler workflow.
This also allows you to set the auto_armed flag internally, which
bypasses the need to raise the throttle stick for the copter to start a
takeoff.
This exposed a problem where we would start running the controllers
before the EKF was at all initialized, if you switched into auto to
early. This now has a check that prevents us from running the mission
state machine until after the origin has been set. This was a suggestion
from @rmackay9.
When combined these options allow you to have the vehicle on the ground,
disarmed in auto with a takeoff waypoint loaded, then just arm the
aircraft and watch it takeoff. This is a feature we've had on quadplanes
for quite awhile now, and it has proven to be very nice for operators.
In the case that you:
- have previously done a successful SmartRTL flight
- get a mid-air gcs failsafe and enter SmartRTL
- recover from that gcs failsafe but remain in SmartRTL
- get another mid-air failsafe
then without this patch you will enter LAND mode.
When determining our failsafe action, we were looking at whether we
should just continue landing. To do that, we ask the current mode if we
are landing. Problem is that SmartRTL was handing back the wrong answer
- it was handing back ModeRTL's answer rather than its own, and
ModeRTL's answer was "yes, I'm landing", as that's the last state that
step 1 in the above list leaves that mode in.
This patch simply hands back the correct answer for, "am I landing"
includes the following changes
winch_update called at 50hz
removed ability to set winch rate from ch6 tuning
remove wheel encoder
call winch library to log at 10hz
fix winch param prefix
