This is my first post here team, so be gentle. I have built quad and tricopters before and had success with the APM and Mission Planner family. I also like to sail and race foiling, single-handed sailboats (UFO and Moth). Most of these boats use an awkward ‘wand’ dragging in the water to detect elevation and actuate a push rod that controls flap angle on a front hydrofoil. The whole system is very mechanical, prone to breakage and the wand literally drags in the water making the boat slow.
I am endeavoring to create a marinized system that would act as a flight controller for my UFO foiler. My thought is to use a sonar sensor to detect elevation above the water and have the APM actuate a servo controlling the front foil flap angle to maintain the elevation.
A couple of questions:
Can APM work independently of an RC controller? In this case, I want the board to boot up and immediately start trying to get me 36 inches off the water. I don’t want to have to use an RC controller control it.
Is there a Mission Planner setting that I can use to accomplish this or will custom software be required?
Does it make sense to control / send instructions to the APM using a RasPi or some other computer acting in place of an RC controller?
