I have been messing around with RC models of all descriptions for three decades, but I have never touched automated models - until now…
I am looking to build an automated boat that, at some point, will end up on the sea. The hull and power systems are not a problem, but the automated part is new to me.
Is ArduRover what I should be looking at? Should I be looking at the APM 2.6 or 3DR Pixhawk?

Has anyone had any experience in doing this?[/quote]
Hi Altsain,
How is your project and experimenting with Automated models going? I’m really interested in how you’re getting on with this as I may have a project you might want to get involved in.
Good timing on your post as I am just going through some experiments right now!
I have been doing land-based tests (way easier walking over to pick up a car when things go wrong!). Got the telemetry all working and now refining the navigation. Once that it is square, I will be transferring all the Gubbins to a boat for water trials - already got the hull sorted for the lake tests, need to work out whether it is suitable for the upcoming ‘bay’ test.
I’ll be adding one of my PixHawk to a Novurania 20’ RHIB over the next few weeks, and I’m curious if you have made any progress with your project.
I’m already using the PixHawk in quite a few unique applications (ATVs, Side-by-sides, full sized vehicles, large main and tail helis, etc.), and I believe the boat will be the most straightforward yet. I have forward looking sonar, and I think I can tie it in to the ArduRover sonar inputs without too much trouble. My Garmin GPS Chart and sonar can spit out an analog signal for the depth, or I can try converting the NMEA 2000 to true J1939 and maybe use some CAN protocols. I haven’t looked into the CAN on the PixHawk too much yet, but need to for some of the ground vehicle OBDII anyway.
And, shifting will be much more like an RC car than a real vehicle, as throttle and shift are on the same lever (unlike a full sized land vehicle). So no more tricky shifting sequencing code for a boat.
The only thing I am a bit hung up on is automating the trim tabs (especially in rough water), but I have been working on my own firmware revisions and may get it figured out soon.
I’d love to hear what you are working on in more detail!
