APM Rover Boat - Hold Mode: Circle vs Stop Moving

Posted by AntimatterCrusader on June 12, 2013 at 9:16am

Hello,

I have what is probably a dumb question but am hoping soemone can help or point me in the right direction... but I just built a boat using APM 2.5, 915mhz 3DR radio. It's working great, I can get it to following waypoints etc - but I am having a small issue

- When it gets to the final waypoint...

- When I put it on Hold Mode...

- And when I point/click "Fly to here" on the map...

WHen it holds/arrives at destination, instead of ceasing to move, it starts to circle almost like APMPlane. It does not seem hold its position, but rather just go in circle of what appears to be the radius of my loiter/waypoint settings. 

Does anyone know how to get it to hold it's position when it arrives at its destination or is placed in hold move? (By hold I mean, not move unless wind or current takes it away, then it will return to that point) 

Any input is appreciated!

    Well, if anyone else has this problem, i figured it out. The throttle channel was reversed. lol, I know. But for some reason when I selected reverse channel on mission planner, it did not actually happen. Took a while to figure that one out. It finally reversed and works great. :)

      Hi matterenergy, did you work out your hold/loiter issue? did you manage to make your boat hold the position without circling?

      Thanks!

      Yes and no. Turns out the issue was: I had some channels reversed, so if the boat went to zero throttle it actually went to full throttle - which resulted in the circling behavior. I fixed that, it no longer circles. Once it reaches its target location, it stops but then will float away. 

      I'd really like to see a feature where after it gets outside it's "Loiter Radius" it powers back up and returns to the center of the circle. 

      Anyway, it's been a while since I've played with this but I just ordered some new parts for my boat. Hope to get it back in the water with updated firmware etc soon!

    That did not work. 

    Also - I have an issue with the boat speeding. I ha have the speed set to 0.5 m/s yet it seems to cruise in the 1-2 m/s range (Full throttle). I have limited the throttle to max 10% in the PIDs but that seems to have no effect. 

    Anyone have any ideas? Any info is appreciated!

    UPDATE: I just had a thought... will setting the "Loiter Radius" to 0 fix this?
