I am currently building an OpenROV 2.6 (Remotely Operated Vehicle)
This is an underwater robot equipped with an HD camera that you can drive from your computer. Multiple sensors could be added and feedback is sent in real-time.
I am building this to eventually try it in “Lac Léman” (Lake Geneva) and while diving in the red sea.
Here’s a video from the first test dive in a swimming pool:
Here are a few build photos:
