C-7 Bottom Explorer
This is a bottom explorer on tracks, but whose motor does not work on a huge supply of batteries, since the generator is capable of working even under water at a depth of 500 meters. The engine gets its air from a huge winch! I added a small kitchenette for coziness, and the ability to watch from the video what is there on the water surface.

Controls
- turn on generator (Ignition key button)
- up down – seat position
- 1 – cruise
- 2 – torpedoes
- 3 – flare
- 4 – light
if the battery of the float video camera runs out, turn off the generator, then the winch will go down and the battery will be charged, then turn on the generator again.
