I live on a lake with a bunch of turtles, baby ducks, geese, snakes, etc. I’m designing and building an underwater drone that will look like a turtle, with a camera on a neck that can be lifted above the water surface, and can look left and right. The idea being I can swim alongside say some baby ducks and get nice close-up video.
The water will be ducted thru the shell, so no props will be visible.
All being done in fusion 360, which I am climbing the steep learning curve of working with surface modelling.
