A method includes generating an anatomical model corresponding to an anatomical feature of a patient, proposing a component for coupling to the anatomical feature of the patient, positioning a virtual model corresponding to the component in a proposed location relative to the anatomical model, generating a planned resection geometry based on a virtual relationship between the virtual model and the anatomical model, tracking movement of a surgical instrument relative to the anatomical feature, and simultaneously displaying the planned resection geometry, the anatomical model, and a graphic corresponding to the surgical instrument on a display based in part on the tracked movement of the surgical instrument relative to the anatomical feature.

An apparatus for providing haptic guidance during manipulation of an end-effector includes a robotic arm. The robotic arm has at least one actuated joint, at least one other joint connected to the at least one actuated joint, and a physical constraint movable by actuation of the at least one actuated joint. The physical constraint limits the motion of the at least one other joint in at least one direction. The apparatus further includes an end-effector configured to be manipulated by an application of external forces and connected to the at least one other joint.

An operator telerobotically controls tools to perform a procedure on an object at a work site while viewing real-time images of the work site on a display. Tool information is provided in the operator's current gaze area on the display by rendering the tool information over the tool so as not to obscure objects being worked on at the time by the tool nor to require eyes of the user to refocus when looking at the tool information and the image of the tool on a stereo viewer.

A surgical system includes a robotic device configured to facilitate performance of a procedure and a computer system communicable with the robotic device. The computer system is programmed to associate a virtual object with an anatomical feature, adjust the virtual object associated with the anatomical feature in response to movement of the anatomical feature during the procedure by monitoring detected movement of the anatomical feature and adjusting the virtual object in response to the detected movement, and control the robotic device based on a relationship between at least one point associated with the robotic device and the virtual object during the procedure.

A surgical system includes a surgical tool, a tracking system configured to obtain tracking data indicative of positions of the surgical tool relative to an anatomical feature, an acoustic device, and a computer system programmed to control the acoustic device to provide acoustic feedback to a user based on the tracking data.

A person support apparatus includes one or more motorized actuators that are braked in different manners depending upon whether or not electrical power is available to the control system. When electrical power is not available, a delay circuit delays closing a first switch that, when closed, short circuits the terminals of one of the motors. When power is available, other switches are opened and closed in a manner that short circuits the terminals of the motor while the first switch remains open. The other switches may be part of an H-bridge. The control system may also detect back emf (electromotive force) generated by the motor when electrical power is available and issue a notification to a technician or other user if an amplitude and/or duration of the detected back emf exceeds a threshold.

An augmented reality device includes a processing unit adapted to process data, and a display unit with a field of view, which is adapted to display a control, control components and first connections between the control components as an extended real image, The control receives sensor data from at least one sensor and transmits actuator signals to at least one actuator of an industrial plant. The processing unit processes from the data a model of the industrial plant with the control, the sensor, the actuator and second connections as plant components, and processes position data of the plant components into the model. The position data of the display unit can be transmitted to the processing unit as GPS data by means of satellites or local position data by means of local sensors, and the processing unit processes the position data of the display unit into the model.

A system comprises a first robotic arm adapted to support and move a tool and a second robotic arm adapted to support and move a camera. The system also comprises an input device, a display, and a processor. The processor is configured to, in a first mode, command the first robotic arm to move the camera in response to a first input received from the input device to capture an image of the tool and present the image as a displayed image on the display. The processor is configured to, in a second mode, display a synthetic image of the first robotic arm in a boundary area around the captured image on the display, and in response to a second input, change a size of the boundary area relative a size of the displayed image.

A method for automatically ascertaining an input command for a robot, wherein the input command is entered by manually exerting an external force onto the robot. The input command is ascertained on the basis of the joint force component attempting to cause a movement of the robot in only one robot joint coordinate sub-space which is specific to the input command. The joint forces are imprinted with the external force.

The various embodiments herein relate to robotic surgical systems and devices that use force and/or torque sensors to measure forces applied at various components of the system or device. Certain implementations include robotic surgical devices having one or more force/torque sensors that detect or measure one or more forces applied at or on one or more arms. Other embodiments relate to systems having a robotic surgical device that has one or more sensors and an external controller that has one or more motors such that the sensors transmit information that is used at the controller to actuate the motors to provide haptic feedback to a user.
