Abstract: A patient side cart for a teleoperated surgical system can include one or more wheels positioned to support the cart for wheeled motion on a ground surface, at least one manipulator portion for holding a surgical instrument, a steering interface having a grasping portion and comprising a sensor positioned to sense turning, fore, and aft forces exerted on the grasping portion to move the cart, wherein the sensor is in signal communication with a drive control system of the patient side cart, and an additional sensor operatively coupled to the drive control system. The additional sensor may be positioned between the steering interface and the wheels on a side of the cart at which the steering interface is positioned, wherein in response to a force exerted on the additional sensor during backward motion of the cart in response to an aft force exerted on the grasping portion, the sensor sends a signal to the drive control system to stop motion of the cart.

Abstract: A system and method of maintaining a tool pose for a computer-assisted medical device with an articulated arm including one or more first joints and one or more second joints, a tool distal to the first joints and the second joints, and a control unit coupled to the first joints and the second joints. The control unit maintains a pose of the tool during movement of the first joints using the second joints by determining a reference coordinate frame for the tool, determining a reference transform of the tool in the reference coordinate frame prior to the movement of the first joints, determining an actual transform of the tool in the reference coordinate frame while the first joints are being moved, determining differences between the reference transform and the actual transform, and maintaining the pose of the tool by driving the second joints based on the differences.

Abstract: A patient side cart for a teleoperated surgical system includes at least one manipulator portion for holding a surgical instrument and a steering interface. The steering interface may include at least one sensor positioned to sense turning, fore, and aft forces exerted by a user to move the cart. The steering interface may further include a coupling mechanism to removably couple the steering interface with the patient side cart. The at least one sensor may be placed in signal communication with a drive control system of the patient side cart when the steering interface is in a coupled state with the patient side cart.

Abstract: Techniques for maintaining instrument position and orientation include a computer-assisted device having a control unit and an articulated structure. The articulated structure includes a plurality of joints and is configured to support an instrument. The control unit is configured to determine an error that is introduced, by movement of a first joint of the plurality of joints, to a position of the instrument, an orientation of the instrument, or both the position of the instrument and the orientation of the instrument; and in response at least to determining that a second joint of the plurality of joints is at a range of motion limit or is about to reach the range of motion limit drive one or more joints of the plurality of joints to partially reduce the error, the one or more joints not comprising the second joint, and provide feedback that not all of the error is reduced.

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 system and method of breakaway clutching in a device includes an arm including a first joint and a control unit coupled to the arm. The control unit includes one or more processors. The control unit switches the first joint from a first state of the first joint to a second state of the first joint in response to an external stimulus applied to the arm exceeding a first threshold, wherein movement of the first joint is more restricted in the first state of the first joint than in the second state of the first joint, switches the first joint from the second state to the first state in response to a speed associated with the first joint falling below a speed threshold, and prevents the switching of the first joint from the first state to the second state when the arm is in a predetermined mode.

Abstract: A cart for supporting one or more instruments during a computer-assisted remote procedure can comprise a base; a steering interface having a portion configured to be grasped by a user; a sensor mechanism configured to detect a force applied to the steering interface by a user; and a switch operable between an engaged position and a disengaged position. The cart may further include a drive system comprising a control module operably coupled to receive an input from the sensor mechanism in response to the force applied to the steering interface and, on the condition that the switch is in the engaged position, to output a movement command based on the received input from the sensor mechanism. A driven wheel mounted to the base of the cart may be configured to impart motion to the cart in response to the movement command.

Abstract: A system and method of collision avoidance includes determining first positions of first joints of a first repositionable arm and second positions of second joints of a second repositionable arm. Distal ends of the first and second repositionable arms are configured to support first and second instruments, respectively. The system and method further include determining first and second virtual boundaries around the first and second repositionable arms, determining an overlap between the first and second virtual boundaries, determining an overlap force on the first repositionable arm due to the overlap, mapping the overlap force to virtual torques on the first joints proximal to the overlap, determining a tip force on a distal end of the first instrument, and applying the tip force as feedback on the first instrument.

Abstract: A system and method of maintaining a tool position and orientation for a computer-assisted medical device include a device with an articulated structure including a plurality of joints and a control unit. The articulated structure is configured to support a tool distal to the joints. The control unit is configured to determine an initial position and orientation of the tool prior to movement of a first joint, determine, while the first joint is moving, a current position and orientation of the tool, determine a difference between the current and the initial position and orientation, and drive at least a second joint based on the difference to maintain a position and orientation of the tool at the initial position and orientation. In some embodiments, the position and orientation of the tool are maintained relative to a reference coordinate frame based on a cause of the moving of the first joint.
