    Abstract: A gripper includes a base unit and finger units coupled to a protruding direction-side of the base unit. Each of the finger units includes a first link structure coupled to the base unit, a second link structure rotatably coupled to the first link structure, and a third link structure rotatably coupled to both the first link structure and the second link structure, and the second link structure includes a finger tip. When the finger unit is pressed in the protrusion direction, the finger tip is brought closer to the base unit in the protrusion direction by the first link structure. When the finger unit is further pressed in the protrusion direction, the finger tip is rotated to be oriented in a direction opposite to the protruding direction in a state in which the finger tip is oriented in a gripping direction that is a direction perpendicular to the protruding direction.

  • Publication number: 20240240576
    Abstract: Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.
