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.

detect mounting of an imaging device to a first manipulator of the plurality of manipulators;

determine a first reference frame for the imaging device based on the mounting of the imaging device to the first manipulator;

control a tool relative to the first reference frame;

detect mounting of the imaging device to a second manipulator of the plurality of manipulators, the second manipulator being different from the first manipulator;

determine a second reference frame for the imaging device based on the mounting of the imaging device to the second manipulator; and

control the tool relative to the second reference frame.

2. The telesurgical system of claim 1, wherein the controller comprises a joint space controller or a workspace controller.

7. The telesurgical system of claim 6, wherein in response to determining the second reference frame for the imaging device, the controller is configured to move the master input control so that the relative position and orientation of the master input control to the user display corresponds to a relative position and orientation of the tip of the tool in the second reference frame for the imaging device.

8. The telesurgical system of claim 1, wherein:

the tool is mounted to a third manipulator of the plurality of manipulators; and

control of the tool is further based on kinematics of the third manipulator.
