While doing a dive yesterday with Trident I had a thought about how cool it would be to have a neutrally buoyant small clump weight attached to the tether about 4-6’ back from the ROV that also had a video camera integrated in it. The assembly would be torpedo shaped and have some fins on the back to keep it stable with the flow. If the assemble had a wifi out cable that could be run up to Trident and attached at the Wifi communication location you could potentially get a live feed of Trident topside in a type of “third person view” of what is going on. I could see this as being useful in certain conditions like operating in tight conditions.
I’ve wondered about the same thing. How can we monitor the ROV itself?
I’ve made a tether camera similar to what you are describing.
(I used a ribbon cable which sadly did not work in the water, so I saw no footage.) The biggest issue I had was that my float was too bulky, so that it jerked the ROV around. So if you try it, make sure that yours is hydrodynamic.
Attaching it to the clump weight is a good idea, though it would be harder to keep it pointed at the ROV.
I agree that being able to see your ROV from third person view wold be very helpful!
