Before Posting an Issue

Hi All,

Before posting an issue or a problem in the ArduBoat Discussion Forum, please check the wiki table of contents, review the firmware release notes in the subforum, and search that subforum for existing answers to your question. Help avoid duplicate threads by finding other members with the same issue and their solution.

When formulating your post, use a descriptive title such as "rover will not navigate to waypoints in the Auto mode" (not "HELP!" or "Problem").

Please include the following information to help diagnose your query:

  • Describe the problem you are having. What is the expected verses the observed behavior?
  • Provide hardware information such as the brand and version of your autopilot, GPS, radio, and compass, as well as any other pertinent details about your rover setup.
  • What version of the APM: ArdurRover2 firmware version are you running?
  • For navigation issues, provide your tlog and/or dataflash log. Click here for instructions on retrieving a dataflash log.

    Hi All,

    Because of the building interest in ROVs I have featured the ROV Project Discussion Thread in the Discussion Forum so that it will be easily located.

    Hi everyone.  The T3 is back and Chris Anderson from 3DR has generously given the green light for boat entries - details here.

    I reckon some of you out there have boats that can take it to the aircraft.  And 200m x 200m space on a lake should be ok.  I am REALLY looking forward to seeing what speed daemon's you people break out.  Get racing!!

    Thanks, Grant.

    Chris, I was going to ask you if you were Editor in Chief at that time at Wired.

    It's based on this story I ran in Wired.

    Hi All,

    For those of you who are interested I have updated my VBox R/C Boat for Autonomous Offshore Competition build discussion thread with pictures of the Navigation Controller and the Navigation Controller Deck Plate.

    Hi Mitchell. 

    We haven't taught the APM how to sail however if someone was keen to do that it would be great. 

    Regarding solar-powered I'm unaware of anyone having done that within this forum.
    As for sailing around the world I see no technical limitation to that.  We could probably use our simulator to simulate it however we would need to alter the model so it could go much faster and thus complete the trip in a day or two rather then weeks.

    Thanks, Grant

  • Is it possible to program an autonomous model to follow GPS coordinates to travel around the world?

    I don't think anyone can really say, but the technology is definitely moving towards that capability. To my knowledge "underwater gliders" ( http://en.wikipedia.org/wiki/Underwater_glider ) have been the most successful long distance, autonomous ocean craft to date. Surface craft have a great many more obstacles to avoid (weather, other craft, legal issues, etc.) so may not be the best platform for this goal. But there are lots of autonomous boat projects out there, but I am not aware of any that have successfully crossed an ocean yet.

  • Hi!

    I'm new to the forum and am looking to find out if there is anyone here who has put together a successful Autonomous, GPS-Guided, either solar-powered or sailboat?
    I've seen a few successful test runs demonstrated on YouTube but I'd like to see how many have achieved this and how far this technology can currently be taken?
    Is it possible to program an autonomous model to follow GPS coordinates to travel around the world?
    I'm very interested to hear from you.

    Thanks all and looking forward to interacting in the group with you all.

    Hi David,

    Thanks for the insight, much appreciated.

    On my Traxxas Villain autonomous boat I had calibrated the GPS/Compass module separately from the boat since it was installed on the removable navigation controller platform. After the navigation platform was mounted on the Villain hull the compass was off by about 30 deg which was caused by the magnetic field of the two motors down in the hull under the navigation controller platform. Moral of this story is to calibrate the GP/Compass module while attached to the hull so that it can compensate for the motor's magnetic field:-)

    However moving this big a hull in three axes and 6 different positions is going to be kind of tough!

    Regards,

Taking the boat round Manoel island.

Hey everyone I'm new here and my thing is USVs. Looking forward to sharing some more cool stuff in the future with you guys and I even sell this thing, And I even just sell the outboard system on its own so check it out.https://www.youtube.com/watch?v=U7ZYi0H6JVk20190403_145513.jpgScreen Shot 2019-09-14 at 2.30.40 PM.png

Rudder control for kontiki

Hi all,I want to install a rudder on to my kontiki, which is like a submarine which floats on the surface and takes a fishing line out to sea.I am thinking of using an apm 2.8 with gps (because thats what i have) to drive a 20kg servo. The gps should point at a point about 3km out from the beach and the kontiki should follow that course until the timer turns off.I would be grateful for any advise how to go about this.

How to connect 2 Brushless Motors and 1 rudder

Hi, I'm new to Pixhawk. I'm making a boat. I do have 2 brushless motor with ESC and 1 servo which is connected to the rudder. How can I connect them to the Pixhawk 2.4.8. What changes should I bring in the parameters? From readings, I come to know that servo should be connected to RC1 and motor to RC3. But what should I do when I have 2 motors, which are kept in both the ends. Thank you
