    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: A computer-assisted device includes a first articulated arm and a control unit coupled to the first articulated arm. The first articulated arm is configured to support an end effector. The control unit is configured to determine a virtual coordinate frame, the virtual coordinate frame being of an imaging device for capturing images of a workspace of the end effector, and the virtual coordinate frame being detached from an actual imaging coordinate frame of the imaging device; receive, from an input control configured to be manipulated by a user, a first instrument motion command to move the end effector; and drive the first articulated arm to move the end effector relative to the virtual coordinate frame based on the first instrument motion command.

    Abstract: Integrated table motion includes a device including a control unit and an arm having one or more joints and a distal portion. The control unit is configured to receive a table movement request from a separate table, determine whether to allow the table movement request based on one or more of whether a type of movement in the table movement request is permitted, whether one or more instruments mounted to the device are within a field of view of an imaging device, or whether one or more instruments mounted to the device are withdrawn into respective cannulas, allow the table to perform the table movement request based on the determining; track movement of the table while the table performs the table movement request; and maintain, using the joint(s) and based on the tracked movement of the table, a position and/or an orientation of the distal portion relative to the table.

    Abstract: A computer-assisted device includes an articulated arm configured to support an end effector and a control unit configured to, when coupled to the articulated arm and a table: determine a virtual coordinate frame before a first joint of the articulated arm is set to a floating mode, configure the first joint to the floating mode, detect movement of the first joint, determine a movement of the table, and drive a second joint of the articulated arm based on the movement of the first joint and the movement of the table. In some embodiments, the virtual coordinate frame is based on a pose of an imaging device and/or is detached from the imaging device. In some embodiments, the control unit is further configured to maintain the virtual coordinate frame in fixed relationship to a top of the table based on motion data received from the table.

    Abstract: A computer-assisted device includes an articulated arm with a plurality of joints and a control unit coupled to the articulated arm. The control unit is configured to send one or more first commands to a plurality of brakes in the articulated arm to begin a release of the plurality of brakes in a predetermined staggered manner, detect a disturbance in a point of interest of the computer-assisted device caused by each brake of the plurality of brakes as the brake is released, and send one or more second commands to the plurality of joints to compensate for the disturbance. In some embodiments, the one or more first commands prevent simultaneous release of two or more brakes of the plurality of brakes. In some embodiments, the one or more first commands cause brakes of the plurality of brakes to release within a predetermined time of each other.
