    摘要: A first input coupling and a second input coupling are coupled to rotatably drive an output coupling at the same time. In one embodiment, the output coupling rotates a robotic surgery endoscope about a longitudinal axis of the output coupling. A first motor drives the first input coupling while being assisted by a second motor that is driving the second input coupling. A first compensator produces a first motor input based on a position error and in accordance with a position control law, and a second compensator produces a second motor input based on the position error and in accordance with an impedance control law. In another embodiment, the second compensator receives a measured torque of the first motor. Other embodiments are also described and claimed.

    摘要: A surgical robotic system has a robotic grasper, a user interface device (UID), and one or more processors communicatively coupled to the UID and the robotic grasper. The system detects a directive to engage or re-engage a teleoperation mode, determines that the system is in a non-teleoperation mode, receives a sequence of user actions through the UID, determines the UID matches a jaw angle or a grip force of the robotic grasper, and transitions into teleoperation mode. Other embodiments are also described and claimed.

    摘要: A virtual reality system providing a virtual robotic surgical environment, and methods for using the virtual reality system, are described herein. Within the virtual reality system, various user modes enable different kinds of interactions between a user and the virtual robotic surgical environment. For example, one variation of a method for facilitating navigation of a virtual robotic surgical environment includes displaying a first-person perspective view of the virtual robotic surgical environment from a first vantage point, displaying a first window view of the virtual robotic surgical environment from a second vantage point and displaying a second window view of the virtual robotic surgical environment from a third vantage point. Additionally, in response to a user input associating the first and second window views, a trajectory between the second and third vantage points can be generated sequentially linking the first and second window views.
