I had an idea for which I couldn’t find a retail solution online. It doesn’t apply to the available OpenROV kits but it does apply to underwater exploration so I wanted to share -
It would be cool to drop a 360 degree camera with a really bright 360 degree light source down on a heavy weight (e.g. downrigger ball). Video feed would travel up the tether to a VR headset. The length of the tether could be controlled by a simple manual or electric reel. I imagine that as the boat travels, the VR headset wearer would have the sensation of flying, with the ability to look around 360 degrees and control camera depth. I think it would be possible to achieve extreme depths with this too.
Any input/ideas are appreciated!
