Abstract: A robot system includes a control device configured or programmed to evaluate a plurality of generated holding posture candidates based on an index including difficulty of interference of at least one of a robot arm or a hand with a surrounding object at a time at which a workpiece is held and generate a movement path.

Abstract: A path generator includes an object setter that sets an object model; a device setter that sets a device model as a model of a robot arm; a path generator that generates a path of the robot arm stepwise; and an interference determiner that performs interference determination on the object model and the device model after having moved along the path, based on a distance between the object model and the device model. If it is determined that there is a possibility of interference between the object model and the device model, at least one of the object setter or the device setter increases a density of point groups of the point group model, and performs interference determination by using the point group model with the increased density of the point groups. If determined that that there is no possibility of interference, the path generator generates a next path.

Abstract: A clip applier system includes: a clip applier that operates a pair of jaws by supplying an operating fluid from a driving device to an opening/closing mechanism, which opens and closes the pair of jaws with a degree of opening corresponding to the amount of the operating fluid, and discharging the operating fluid from the opening/closing mechanism to the driving device; an operation device that outputs an operation signal corresponding to the amount of operation performed on an operation tool; a detection device that outputs a signal corresponding to the degree of opening of the pair of the jaws; and a control device that performs an opening degree control. In the opening degree control, the control device controls the motion of the driving device according to a difference between a command based on the operation signal and an actual value based on the signal from the detection device.

Abstract: A hydraulic medical instrument mounted to a distal end of a robotic arm includes: a linking structure that is linked to the distal end of the robotic arm; an insertion pipe extending from the linking structure; and a hydraulic mover provided on a distal end of the insertion pipe. The hydraulic medical instrument further includes a hydraulic driving source that includes at least one hydraulic pressure-dedicated shaft provided in the linking structure, the hydraulic driving source supplying a hydraulic liquid to the hydraulic mover and collecting the hydraulic liquid from the hydraulic mover by rotation or linear motion of the hydraulic pressure-dedicated shaft. When the linking structure is linked to the distal end of the robotic arm, the hydraulic pressure-dedicated shaft is coupled to a motor disposed in the distal end of the robotic arm.

Abstract: To easily acquire an image of a tip end portion of a surgical instrument attached to a manipulator arm even when the surgical instrument is bent, a surgical system includes manipulator arms, a manipulation unit, and a controller. The manipulator arms include: a first manipulator arm including an instrument holder holding a first surgical instrument including an instrument bendable portion; and a second manipulator arm including an instrument holder holding an endoscope assembly including an endoscope bendable portion and a camera at a tip end portion of the endoscope assembly. A method of controlling the surgical system controls the endoscope assembly such that the endoscope assembly is bent so as to follow bending of the first surgical instrument that is bent based on an operating command.

Abstract: A hydraulically driven clip applier includes: a pair of jaws that respectively include, at a tip end, a pair of gripping portions capable of holding a clip therebetween and are coupled to each other in a manner to allow the pair of gripping portions to be opened and closed and when a base end of the pair of jaws is opened, close the pair of gripping portions; and an opening/closing driving mechanism that is a cylinder mechanism including a rod and when supplied with an operating fluid, extends the rod. Base end portions of the pair of the jaws are positioned at a distance from each other. The opening/closing driving mechanism is configured to position a tip end of the rod between the base end portions of the pair of jaws and open the base end of the pair of jaws by extending the rod.

Abstract: A rotary actuator includes: a housing including an interior space in which a vane is disposed; and a cover that is attached to the housing and covers the interior space. An annular seal groove having a triangular cross-sectional shape is formed between the housing and the cover in a manner to surround the interior space, and an outer sealing member is inserted in the seal groove.

Abstract: A printed circuit board assembly is configured and arranged so that memory modules are mounted thereto. At least two connectors are mounted on a printed circuit board. The connectors are configured so that the memory modules are connected thereto. An electromagnetic wave absorption sheet is provided to at least one of the connectors. The electromagnetic wave absorption sheet is attached so as to cover a side surface of the one connector facing a side surface of the other connector.
