OPEN SOURCE MARINE AUTOPILOT

Hello All

I have spent a small fortune on autopilot brains & repairs over the years for my 38' sailboat, and I am in need of another brain.

My Raymarine 12 Volt Type-1 linear drive is still in good working order and as well as the input components, from the dead Navman AP. RFB, Gyro, Compass

I have been researching Arduino as a solution. I'm very new to the Arduino world, but not the controls world as I have been in the building automation & process control field for many years.

So, I am looking for guidance, if anyone is willing?

  • Material list
  • Wiring diagrams
  • Do's/Don'ts
  • Watch out fors
  • Sketches

Let me know your thoughts

tip 1: spend a few days on the tutorial site to pick up the details of the arduino programming language (C++ ++)

tip 2: get every sensor to work first in a private sketch to learn the ins and outs of that typical sensor. For most sensors there are more than one library, check them and select one that fulfils your needs.

3) write down your requirement both functional and non functional

4) Then it becomes time to integrate all sensors/display etc into one sketch,

What does RFB mean in this context?

Check out the RPN4 from www.ontargetmarine.com, feature summary: http://ontargetmarine.com/feature-summary

It started out as an Atmega644A married to an Uno, and ended up as this: Contact member Skyjumper to purchase one.

I see two major problems - your trying to build something which needs to survive in a very harsh environment and its also something upon which your life will depended. Yes you can build something that will work but with this kind of kit, in that environment not for very long and not reliably.

Your insurance company may also object. I would not go for a sail around my local harbour with you and a rig like that let alone into deep water.

Would you sail with this? http://www.nexusmarine.se/products/marine-instruments/transducers/the-nexus-server/

Thank you all for your replies!! I love forums!!, for the knowledge shared

I was inspired from this blog http://themarineinstallersrant.blogspot.com/ and reached out to Jack for assistance in my quest in life long learning. Thanks Bill for the blog!, and Thanks to Jack for sharing!! Do a YouTube search for the same.

My goal is to share my experience in the build process as a new Arduino user. So far this is fantastic!! I am not interested in any commercial systems, in the past 5 years I have dropped nearly 5K$ in systems & repairs. I think this will be more fun and educational for me and anyone else that is interested.

I have ordered my Arduino Mega’s, a Pololu motor control, & gyro compass this evening… Let the fun Begin!!

Cheers

Happy New Year to everyone. I have built an Open Source Autopilot that steered my 40 foot sailboat up the NW inside passage 400 miles. I worked on it at home this fall and made a little video. You can see here

It has compass steering, GPS waypoint to waypoint steering with cross track error correction, a Tack mode (90 degree turn).

Project files are on a Dropbox site here: https://www.dropbox.com/sh/l1l1432c9vfs4g1/7PJUMgsj0E

I am posting it here to see if there are other sailors/Arduino fans who want to participate.

@coyotewaits Well done

I am very interested in your project are you still working on it?

Hello white74 (Jack?) I am just on the way making the same thing. My boat is slightly larger and there is an old robertson autopilot drive installed, which is hydromechanic like Yours, but has a 20 Amps motor. I want to realize this project in a much more simple way. To get a course into the autopilot, I will use the whole boat. That means, the autopilot will measure the course the moment it is switched ON, and will stay to this course until ist is switched OFF.

I will use the Arduino Uno, as compass the GY-88 breakout board. The most expensive part will be the motor driver, which has to drive 20amps + some headroom. The rudder feedback is a potentiometer connected to an ANIN of the Arduino. Greetings mariner

I'd go for a sail with or without the NAV ha ha, but that's just my love for adventure ... :grin:
