Technology Factsheet

Hitachi Submersible

Category: Robotics > Characterization and Inspection > Underwater System
Reference # : Model No :

The submersible crawling swimming robot is for investigating submersed environments within Fukushima, and can be used to investigate underwater leakage points of the retained water. A feature of this robot is the use of six thrusters (4 vertical, 2 horizontal) to enhance free movement in water, and one set of crawlers to achieve both crawling and swimming movement. Through the crawling movement, the robot can not only run along the bottom of a water pool but can also change posture to avoid obstacles while swimming and after swimming, to move along a wall through suction.
