Glass sphere type pressure housing including titanium band and a multi-joint underwater robot system for deep sea exploration using the same

A deep-sea exploration multi-joint underwater robot system, comprising:

• a multi-joint underwater robot configured to have a plurality of first pressure housings and a plurality of second pressure housings for withstanding a deep-sea water pressure and shielding built-in equipment from an intrusion of seawater, to perform a proximity and precision exploration of a seabed terrain while obtaining marine research data to transmit underwater status data, and to have a hydrodynamic streamlined body for an underwater mobility;
• a mothership configured to receive and store the marine research data and the underwater status data, monitor moving directions of the multi-joint underwater robot, and control the moving directions;
• and
• a depressor configured to have a third pressure housing, be linked with the mothership by a primary cable and with the multi-joint underwater robot by a secondary cable, and prevent a water resistance of the primary cable from being transmitted to the multi-joint underwater robot, wherein
• the plurality of first pressure housings have a spherical formation and are mounted on a robot body frame of the multi-joint underwater robot, the plurality of second pressure housings have a cylindrical formation and are mounted between a plurality of left and right legs, respectively, and the third pressure housing has a cylindrical formation and is mounted in a platform of the depressor.
