Currently, there are 50,000 active ships in the world, and each single engine of these ships is routinely checked. Suppose an engine has seven cylinders, then there are 350,000 cylinders in total. At any time, some of them are opened, and specialists go inside of them for check-up.
Smart Camera Kirari-NINJA for Engine Maintenance, which was named after the black body and the sharp eye, is RICOH THETA equipped with lights and coolant. It can go inside of a cylinder through a small opening that a man cannot go through, and light up and take clear images of the interior of the cylinder. Therefore, Kirari-NINJA cuts down on labor and permits check-up without opening an engine, which is time-consuming and costly, for adequate maintenance anytime.
Here are some pictures of inside of a cylinder taken by Kirari-NINJA. Please enjoy the strange and yet interesting feeling as if you are inside an engine cylinder.
