Good day all
I am busy building my second drone :
I have done a successful maiden flight, but I would like to test some of the autonomous
flight modes as I have programmed into the pixhawk. I am very cautious to create a situation
where my drone can fly-away !!! And this raised a question with me about how I can
regain control of my drone if RTL was activated. I was told that there are priority levels assigned
to the flight modes but I cannot find it on google. What this person suggested was , if RTL has the
highest priority, then no other flight mode can override that.
So the question is :
If RTL was activated, can I regain control if I am within range ? What happens if the trigger for RTL was a low battery ? If I see my drone frying off, how can I then stop it ??
Any comments would be appreciated !
Good day all
My second drone setup:
Bl-Heli32 (40A) ESC
RXSR Frsky receiver
Pixhawk 2.4.8 ( running APM copter V3.5.5 )
CADDX Turbo SDR1 1200TVL camera
TBS Unify Pro 5G8 HV Race (MMCX) VTX
MiniOSD for Mavlink OSD on FPV
FPV running on separate PDB from 3S
I have tested the automatic functions ( loiter , stabilise , Alt hold, Stabilise-simple, landing and RTL ) and they all work well.
I did however notice that you have to be READY if you want to interrupt a RTL. If you switch from RTL to stabilise, then your controller-gymbals are now active again and depending on their settings, you might find your copter shooting up or starting a fall !!!! So be prepared. ( Just writing this for anyone that should look this up that is also building a pixhawk drone for the first time !! )
So, yeah .. thanks for the comment Javier.
This then is phase I and phase II complete !!
Phase III : telemetry to my Taranis
Phase IV : Telemetry to Mission Planner
Many thanks for your response. That gives me some comfort when I go and test all the functions that I have programmed in.
If RTL does go flying off when I test RTL, then I can regain control.
Will report back when I have tested the automatic functions.
If you're using a radio, just change mode with one of the radio sticks as usual. It will override the RTL.
