A male member and tool changer for downsizing and preventing damage to proximity sensors; a male member includes a cam adapted to pivot between an engagement position at which the cam engages with a lock pin of a female member and a disengagement position at which the cam moves out of the engagement, and a cylinder unit adapted to pivot the cam between the engagement position and the disengagement position. A first proximity sensor and the second proximity sensor are assembled onto a cylinder sidewall of the cylinder unit and first and second detection surfaces of the proximity sensors are revealed in a cylinder chamber. The first detection surface is placed at a position facing on a piston when the cam is located at the disengagement position and the second detection surface is placed at a position facing on the piston when the cam is located at the engagement position.

A system and method for tool exchange during surgery for cooperatively controlled robots comprises a tool holder for receiving a surgical tool adapted to be held by a robot and a surgeon, a tool holding element for constraining downward motion of the tool while allowing low force removal of the surgical tool from the holder, a first sensor for detecting if the surgical tool is docked within the tool holder, and a selector for automatically selecting different movements or actions of the tool holder to be performed based upon information detected by the first sensor. The system and method of the present invention provides an advantage to an often slow moving cooperative robot, by increasing the speed by which the tool holder may move in the direction away from the patient.

Provided are a tool exchange device and a tool exchange system that enable management of a coupling state according to a tool to be fixed. A tool exchange device including a male member to be detachably attached to an apparatus side and a female member to be detachably attached to a tool side includes: a proximity sensor provided in the male member; and a target provided in the female member, the target corresponding to the proximity sensor, and the target is provided in the female member in such a manner that a distance between the target and the proximity sensor in a state in which the male member and the female member are coupled together is adjustable.

Techniques are described for testing whether an end effector, or component thereof, is correctly or incorrectly installed to a manipulation system. In an example, a manipulation system can include a manipulator arm configured to receive an end effector having a first moveable jaw, a transducer configured to provide first effort information of the end effector as the end effector moves, and a processor configured to provide a command signal to effect a first test move of the first moveable jaw, and to provide an installation status of the of the end effector using the first effort information of the first test move.

The invention relates to a gripping device (12) comprising a main body (58) which can be coupled to a robot, at least one adapter portion (66, 67) which is movable on the main body along a gripping axis (42), and at least one gripping element (38, 39) which can be detachably locked to the adapter portion, wherein the adapter portion comprises a locking mechanism (68a, 68b) having at least one locking element (70a, 70b) which, in a locking position, locks the gripping element to the adapter portion, wherein an unlocking element (76a, 76b) is arranged on the main body, and wherein the locking mechanism can be moved along the gripping axis into an unlocking position in which the unlocking element transfers the locking element from its locking position into a release position in which the gripping element can be detached from the adapter portion.

Apparatus and methods for adaptively retooling robots include programmable adapters for detachably connecting at least one robotic peripheral to a robot, providing peripheral information associated with the robotic peripheral, and causing the robot to adaptively reconfigure based on the peripheral information.

The present invention relates to a robotic arm with a tool interface (16) comprising an electronically controllable tool attachment for affixing a tool to the interface.

A robotic tool changer includes a locking feature, and may be made washable by sealing against fluid incursion. The tool changer comprises a master unit and one or more tool units, and it transitions between decoupled and coupled states by rotation of one part relative to another. The rotation displaces rolling members in the master unit, such as balls, from a retaining surface to a locking surface which is sized and positioned to force the rolling members against a coupling surface of the tool unit. A deformable pin interposed between the retaining and locking surfaces resists movement of the rolling members therebetween, requiring the application of force. The pin remains deformed, and continues to exert a force on the rolling members, when the robotic tool changer is in the coupled state, providing a locking feature which automatically and positively resists any inadvertent decoupling of the tool changer.

Generally, a sterile adapter for use in robotic surgery may include a frame configured to be interposed between a tool driver and a surgical tool, a plate assembly coupled to the frame, and at least one rotatable coupler supported by the plate assembly and configured to communicate torque from an output drive of the tool driver to an input drive of the surgical tool.
