From BlueRobotics, a cool ROV that works with APM and the Robot Operating System (ROS. 

Here it is with APM inside: 

And here it is in action:

What is the great agility in the water.

I am appreciate that they are open for the ROV hardware.

The OpenROV team wrote to tell me that their sub supports ROS, too.

Hi Chris,

Is the ROV being operated in the Stable mode because a ROV is really not autonomous?

ahhh there's life left in her yet captain *scotty voice* I remember the blue thrusters on kickstarter last year, it was a great project idea. Of course you can make your own thrusters using brushless motors, dismantled and dipped in epoxy. but I wonder if the OpenROV group developed other thruster builds?

I'm pretty sure the ROV is going to be stable-only (I wonder how the barometer functions?), GPS underwater isn't that efficient if my memory serves me correctly. Sonar & IR functions could be cool to implement, also optical flow might work. It would be great to see a point cloud rendering of a lake or sea bed.

Do you really need electronics (APM/ROS) if your operating this thing by tether?

@Acorn,

If you put the APM in the Stable (FBWA) Mode it would take care of helping to keep the ROV stable in pitch, roll, and yaw without requiring the ROV operator to be constantly doing so while attempting to move the ROV around in the water to perform tasks.

Sharing Jiro's sentiment- amazing agility! ROVs have been on my list for a while, and now is looking like a prime time to get my feet wet... :)

My spare APMs are waiting for the water.

But, I need three more thrusters in addition to cloud funding three thrusters.

Do we need tether wire ?

Personally I don't see the benefit of using APM to keep an underwater ROV stable.  The same thing can be easily accomplished by properly centering the buoyancy and ballast where the vehicle has a long righting arm.  As for barometer and GPS, these won't function underwater.  The only reason I can think that someone might pick APM or ROS for an ROV is if they already have the hardware and/or are familiar with it as a development platform.

I, on the other hand, hope to take a much "lower tech" approach.  I will be using the same Blue Robotics thrusters, but the electronics will be more in keeping with what is typically used in the ROV industry.

Bigkahuna,

The barometer on the APM could be useful for detecting a leak in the WTC.  Better than using a micro switch and an aspirin if you ask me.  I agree with Tom that the APM would also take a bit of the work load off the pilot. I may have to get another toy.
