Patent number: 11110594Abstract: A fine work assistance system is configured such that a parallel link mechanism is used for a slave manipulator activated by a master operation, and a precise motion for microsurgery or the like is performed by remote control. In a slave unit of a master-slave manipulator, the parallel link mechanism with multiple degrees of freedom is used for a link mechanism in which an end effector is movable with respect to a base. Moreover, a tip operation part is driving by a hydraulic driving mechanism such that a plurality of linear actuators supported by the base move one ends of links so as to move the end effector, and the slave unit is activated in response to a user operation on the master unit. This achieves the precise motion of the end effector and causes the end effector to perform operations for a precise work.Type: GrantFiled: November 1, 2016Date of Patent: September 7, 2021Assignee: Kyushu University, National University Corp.Inventors: Susumu Oguri, Makoto Hashizume, Masaharu Murata
