Hi I was wondering if there is any insight to a problem I am facing re my steering.
I am building a survey usv and it has a front propulsion motor mounted perpendicular to the end of a steering shaft with a steering box rotating the shaft. It’s a trolling motor that I have modified to work for my vessel. This means it has a constant ability to steer 360 degrees and doesn’t have a return to centre position.
The issue I have is in auto mode it seems to get lost and try searching for its track or RTL but can never find it, I beleive this is because the fc doesn’t know where the steering is facing, is this true or is it still in the tuning.
It seems to loiter ok until it get too far away and then it starts loosing it, it’ll do large circles or even figure of eights. Compass and ahrs orientation are set correctly and the external compass is set to use.
