A system includes an input control, an instrument, a memory storing instructions, and one or more processors coupled to the memory. A first axis of a first coordinate frame is defined along a length of the input control and is associated with an orientation of the input control. A second axis of a second coordinate frame is defined along a length of the instrument and is associated with an orientation of the instrument. When executing the instructions, the one or more processors perform steps including, while in a following state, receiving a first command corresponding to a rotation of the input control about the first axis, in response to the first command, generating a second command to rotate the instrument around the second axis without rotating the instrument around any axis orthogonal to the second axis, and controlling movement of the instrument according to the second command.

Systems and methods for operating a robotic surgical system are provided. The system includes a surgical tool, a manipulator comprising links for controlling the tool, a navigation system includes a tracker and a localizer to monitor a state of the tracker. Controller(s) determine a relationship between one or more components of the manipulator and one or more components of the navigation system by utilizing kinematic measurement data from the manipulator and navigation data from the navigation system. The controller(s) utilize the relationship to determine whether an error has occurred relating to at least one of the manipulator and the navigation system. The error is at least one of undesired movement of the manipulator, undesired movement of the localizer, failure of any one or more components of the manipulator or the localizer, and/or improper calibration data.

Master-to-slave orientation mapping when misaligned

A system includes a master manipulator and a controller. The controller determines, before the system enters a following mode, a relative orientation between an orientations of an axis of the master manipulator in an eye frame and a corresponding axis of a slave instrument tip in a camera frame. After the system enters the following mode, the controller determines whether an orientation misalignment between the orientations of the axis of the master manipulator and the corresponding axis of the slave instrument tip is less than or equal to a maximum permitted orientation error. When the orientation misalignment is less than or equal to the maximum permitted orientation error, the controller receives a command indicating a desired orientation of the slave instrument tip from the master manipulator and commands the system to orient the slave instrument tip based on the desired orientation of the slave instrument tip and the relative orientation.

Rendering Tool Information As Graphic Overlays On Displayed Images Of Tools
