Alignment difference safety in a master-slave robotic system

A method of operating a robotic control system comprising a master apparatus in communication with an input device having a handle and a slave system having a tool having an end effector whose position and orientation is determined in response to a position and orientation of the handle. The method involves producing a desired end effector position and a desired end effector orientation of the end effector, in response to a current position and a current orientation of the handle. The method further involves causing the input device to provide haptic feedback that impedes translational movement of the handle, while permitting rotational movement of the handle and preventing movement of the end effector, when a rotational alignment difference between the handle and the end effector meets a first criterion. The method further involves re-enabling translational movement of the handle when the rotational alignment difference meets a second criterion.

Fine work assistance system and fine work manipulator

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.
