  • Patent number: 11610168
    Abstract: Disclosed is a method for analyzing a risk of a cooperator supply chain. The method calculates a risk score based on text data associated with an evaluation target company, provides visual information on the risk score of the evaluation target company through a bar graph, a tracking graph, a scatter plot graph, a network diagram, and a map diagram, and generates a chat room for managing a supply chain between the evaluation target company and the cooperator to support real-time communication.

  • Publication number: 20230075011
    Abstract: A parallel-type gripper according to an embodiment of the present invention includes: a pair of jaws that are opposite to each other; and a parallel-type driving module in which the pair of jaws are movably connected in a horizontal direction such that they approach or move away from each other, and moving the pair of jaws in the horizontal direction so that the pair of jaws grip an object.

  • Publication number: 20220379496
    Abstract: Provided is a robot gripper. The robot gripper comprises: at least two finger units which symmetrically face each other; finger tips which are provided at the terminal ends of the finger units and linked with the operation of the finger units; and a driving unit connected to the finger units so as to operate the finger units. When the finger units are operated, the finger tips pinch-grip an object by moving toward an inner area, which at least two of the finger units form by facing each other, while adapting to conflicts with constraints of the external environment. A force applied to the finger tips in order to enable the pinch grip can act in a direction that raises the object while being applied toward the inner area, or act in a direction lowering the object while being applied toward the inner area.
