摘要： Scene perception systems and methods are described herein. In certain illustrative examples, a system combines data sets associated with imaging devices included in a dynamic multi-device architecture and uses the combined data sets to perceive a scene (e.g., a surgical scene) imaged by the imaging devices. To illustrate, the system may access tracking data for imaging devices capturing images of a scene and fuse, based on the tracking data, data sets respectively associated with the imaging devices to generate fused sets of data for the scene. The tracking data may represent a change in a pose of at least one of the image devices that occurs while the imaging devices capture images of the scene. The fused sets of data may represent or be used to generate perceptions of the scene. In certain illustrative examples, scene perception is dynamically optimized using a feedback control loop.

摘要： A system includes a robotic manipulator including a serial chain comprising a first joint, a second joint, and a first link. The system further includes a processing unit including one or more processors. The processing unit is configured to receive first link data from a first sensor system located at the first link, generate a first joint state estimate of the first joint based on the first link data, and generate a second joint state estimate of the second joint. The processing unit is further configured to apply a first weight to the first joint state estimate to generate a first weighted joint state estimate, apply a second weight to the second joint state estimate to generate a second weighted joint state estimate, and control the first and second joints based on the first weighted joint state estimate and second weighted joint state estimate.

摘要： A teleoperated system includes a master grip and a ratcheting system coupled to the master grip. The ratcheting system is configured to be coupled to a slave instrument. The ratcheting system is further configured to align the master grip with the slave instrument by determining a commanded angular velocity for the slave instrument based on a command from the master grip, determining a current alignment error between an alignment of the master grip and an alignment of the slave instrument, and altering the commanded angular velocity for the slave instrument based on the current alignment error. In some embodiments, the ratcheting system is further configured to introduce a control system error to alter the commanded angular velocity. In some embodiments, the current alignment error is a rotation angle error between the alignment of the master grip and the alignment of the slave instrument.

摘要： A method comprises receiving first shape data from a first elongated optical fiber section in a first shape sensor. The first elongated optical fiber section extends between a reference fixture and a first anatomic fixture coupled to a patient anatomy. The method further comprises determining a pose of the first anatomic fixture from the first shape data and tracking a pose change for the first anatomic fixture.

摘要： 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.

摘要： A robotic system includes a processor that is programmed to determine and cause work site measurements for user specified points in the work site to be graphically displayed in order to provide geometrically appropriate tool selection assistance to the user. The processor is also programmed to determine an optimal one of a plurality of tools of varying geometries for use at the work site and to cause graphical representations of at least the optimal tool to be displayed along with the work site measurements.
