Abstract: A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations and displayed on a display screen from the perspective of a specified viewing point.

To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations are displayed along with indications of range of motion limitations on a display screen from the perspective of a specified viewing point.

Abstract: Two surgical instruments are extended through a single guide tube in a telemanipulation system. A control system moves each of the instruments in all six Cartesian degrees of freedom independently of any guide tube movement in response to telemanipulation inputs received from masters.

Abstract: A motor control amplifier for position feedback control is provided utilizing the inherent inductor and/or resistor dynamics of the motor. The motor control amplifier applies a voltage to the motor equivalent to the electrical motor resistance multiplied by the current of the motor, canceling out the electrical motor resistance, and thereby providing position feedback control through motor inductance. A command term/voltage could be added to make the position feedback control relative to a setpoint. Further, a motor control amplifier for feedback control to arbitrary dynamics is provided. The motor amplifier applies a voltage proportional to a wave command signal. The motor amplifier has a sensing component to provide a wave return signal to construct a wave transformer from the electrical motor resistance.

Abstract: A medical robotic system having non-ideal actuator-to-joint linkage characteristics, includes a control system including a proximal control loop with actuator sensor feedback to control dynamic response of an actuator coupled to a distal joint which in turn, is coupled to an end effector to provide a degree of freedom movement of the end effector, a distal control loop with distal joint sensor feedback and feedforward to the actuator to ensure steady-state convergence of the distal joint position, and an end effector control loop with end-point sensor feedback to control the end effector position to reach a commanded end effector position.
