  • Publication number: 20220175479
    Abstract: A surgical operation system includes an operation unit, a hand control unit, and a controller. In a normal operation mode, a normal operation command generator calculates a target posture of a surgical instrument based on a displacement of a handle, the displacement being detected by a detector, and generates a normal operation command to operate a wrist joint such that the surgical instrument takes the target posture. In a bendable joint operation mode, a bendable joint operation command generator generates a bendable joint operation command to change a bending angle of a bendable joint based on the displacement of the handle, the displacement being detected by the detector.

  • Publication number: 20220153396
    Abstract: An underwater work system of the present disclosure acquires a relative position of an underwater vehicle relative to a surface ship at the start of searching work, the relative position being measured based on a sound wave transmitted from a wave transmitter. The underwater work system calculates a position of the underwater vehicle based on the acquired relative position. When a measurement error region whose center corresponds to the calculated position of the underwater vehicle and an expected laid region of a pipeline extending in a predetermined direction overlap each other, the underwater work system moves the underwater vehicle to such a position that the measurement error region and the expected laid region do not overlap each other, and then, makes the underwater vehicle perform crossing detection in which the underwater vehicle detects the presence or absence of the pipeline while crossing the expected laid region.
