A
mini submarine is a specially designed submarine having different size and shapes.
Inside its hull, there is a round-shaped cabin made of very thick metals. A
crew man can look outside through a window. It is also equipped with very
strong lamps, because the sunlight could not reach the bottom of the sea.
A
mini-submarine is very useful for repairing the offshore oil drilling
instruments, investigating the wrecked ships, and finding some valuable
minerals that might exist in the seabed.
A
mini-sub is equipped with an arm which can be moved and controlled from the
hull. The arm is able to hold or take some objects from the sea floor.
