【The structure on movement in the water】

《As to the robot in the water,the structure on the movement of a submarine has frequently been used》

A ship in the water which was invented by a Dutch inventor, Cornelis Drebbel in 1620 is the originator of a submarine. In 1898 when its shape became the modern one. Judging from it,the history of the submarine reaches more than a century. It’s as long as the history of a car.

Neither a telescope nor a torpedo is equipped in the robot like a submarine,but lots of the robot which are used in the water have the same structure for moving as the submarine basically.

It navigates underwater and surfaces,adjusting the weight of ballast tank with its screw as propelling force. As it has so long history that its system is completed mechanically like the driving way of a wheel.

Controlling on the movement in the water itsel isn’t so hard, but its work in the sea,lake or river,so it’s hard for us to operate it by making sure of it with our own eyes.
