  • Publication number: 20150366625
    Abstract: A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations are displayed along with indications of range of motion limitations on a display screen from the perspective of a specified viewing point.

  • Publication number: 20150297300
    Abstract: To perform a tool exchange in a medical robotic system, tool is retracted back into an entry guide from a deployed position and pose so that an assistant in the operating room may replace it with a different tool. While the tool is being retracted back towards the entry guide by user action, its configuration is changed to an entry pose while avoiding collisions with other objects so that it may fit in the entry guide. After the tool exchange is completed, a new tool is inserted in the entry guide and extended out of the guide by user action to the original position of the old tool prior to its retraction into the entry guide while the tool's controller assists the user by reconfiguring the new tool so as to resemble the original deployed pose of the old tool prior to its retraction into the entry guide.

  • Publication number: 20130197672
    Abstract: A cascade control system includes pass-through controller and a Proportional-Integral-Derivative (PID) controller, wherein the PID controller controls a first output of a device to generate an input to drive the device. The pass-through controller provides a setpoint to the PID controller and controls a second output of the device. The first output and optionally also a derivative of the first output is passed to the pass-through controller so that a pass-through control algorithm can be implemented that results in the input to the device only having terms of the second output, thereby avoiding dynamic interaction between the control loops of the pass-through controller and the PID controller.
