Abstract:
Integrated table motion includes a teleoperated device comprising an articulated structure and a control unit. The articulated structure comprises a first plurality of joints, a plurality of links coupled by the first plurality of joints, and a plurality of actuators coupled to drive motion of the articulated structure. The control unit comprises one or more hardware processors. The control unit is operatively coupled to the articulated structure. The control unit is configured to receive a table movement request from a command unit of a table, the table being separate from the teleoperated device; determine whether the table movement request should be allowed; and in response to a determination that the table movement request should be allowed, allow the table to perform the table movement request.
Abstract:
Disturbance compensation in teleoperated devices include a first articulated arm, a second articulated arm, and a control unit. The control unit is configured to detect a first disturbance to the first articulated arm occurring at a first time, the first disturbance moving an imaging device supported by the first articulated arm away from a first orientation of the imaging device toward a second orientation of the imaging device, and after the first time: receive a first indication of a first user input to move an end effector supported by the second articulated arm while the imaging device is not at the first orientation, determine, based on the first indication, a first command for moving the end effector as if the imaging device has the first orientation, and command a second plurality of actuators of the second articulated arm to move the end effector according to the first command.
Abstract:
Techniques for maintaining instrument position and orientation include a computer-assisted device having an articulated structure and a control unit. The articulated structure includes a plurality of joints and is configured to support an instrument. The control unit is configured to determine a reference frame based on a type of a disturbance that causes a movement of a first joint of the plurality of joints; determine, in the reference frame, a first change to the instrument due to the disturbance; and rive at least a second joint of the plurality of joints to reduce the first change. The first change comprises: a change in a position of the instrument, or a change in an orientation of the instrument, or a change in both the position of the instrument and the orientation of the instrument.
Abstract:
Techniques for operating a kinematic structure by manual motion of a link coupled to the kinematic structure include a system having a kinematic structure configured to support an instrument and a processor. The processor is configured to place the system in a clutching mode; transition the system from the clutching mode to a set-up mode in response to detecting a joint operation of the kinematic structure; while in the set-up mode, determine an input displacement of a link from an initial positional relationship relative to a portion of the kinematic structure to a displaced positional relationship relative to the portion of the kinematic structure; and while in the set-up mode and in response to the determined input displacement, drive the kinematic structure so that the link returns toward the initial positional relationship relative to the portion of the kinematic structure.
Abstract:
Methods, apparatus, and systems for controlling a telesurgical system are disclosed. In accordance with a method, a first tool connected to a first manipulator of the system, and a second tool connected to a second manipulator of the system, are controlled. A swap of the tools such that the first tool is connected to the second manipulator and the second tool is connected to the first manipulator is then detected. The first tool connected to the second manipulator and the second tool connected to the first manipulator are then controlled.
Abstract:
Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. A set-up mode employs an intuitive user interface in which one or more joints of the kinematic linkage are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. Embodiments of the invention can provide for manual movement of a platform supporting a plurality of surgical manipulators or the like without having to add additional input devices.
Abstract:
The present invention is directed to an articulate minimally invasive surgical endoscope with a flexible wrist having at least one degree of freedom. When used with a surgical robot having a plurality of robot arms, the endoscope can be used with any of the plurality of arms thereby allowing the use a universal arm design. The endoscope in accordance to the present invention is made more intuitive a to a user by attaching a reference frame used for controlling the at least one degree of freedom motion to the flexible wrist for wrist motion associated with the at least one degree of freedom. The endoscope in accordance to the present invention attenuates undesirable motion at its back/proximal end by acquiring the image of the object in association with the at least one degree of freedom based on a reference frame rotating around a point of rotation located proximal to the flexible wrist.
Abstract:
Disturbance compensation in computer-assisted devices include an articulated arm comprising one or more first joints and one or more second joints and one or more processors coupled to the articulated arm. The articulated arm is configured to support an end effector. The one or more processors when executing instructions are configured to: detect a disturbance to the one or more first joints, the disturbance causing a point of interest associated with the end effector to move; determine a predicted motion of the point of interest based on the detected disturbance; and drive the one or more second joints to move the point of interest based on an error in a position of the point of interest indicated by the predicted motion.

Abstract:
Integrated table motion includes a computer-assisted device. The computer-assisted device includes an articulated arm and a control unit coupled to the articulated arm. To support integrated motion with a table physically separate from and communicatively coupled to the computer-assisted device via a communications connection, the control unit is configured to receive a table movement request from a table command unit of the table, determine whether the table movement request should be allowed, and allow the table to perform the table movement request based on determining that the table movement request should be allowed.
