    摘要: A method and apparatus for controlling a haptic device. In one embodiment, the haptic device includes an actuator; an actuator sensor, producing an actuator signal indicative of the actuator velocity; a load; a load output sensor producing a load output signal indicative of the load position; and a controller in electrical communication with the load output sensor, actuator sensor and actuator. The controller controls the actuator in response to the actuator signal and the load output signal to provide a haptic response to a user. In one embodiment, the method for controlling an actuator of a haptic device includes the steps of producing an actuator signal indicative of the velocity of an actuator; producing a position signal indicative of the position of a load; and controlling the actuator in response to the actuator signal and the load output position signal to produce a haptic response to a user.

    摘要: A computer-implemented method for guiding an instrument, comprises determining, by a processor associated with a computer, a current orientation angle of an instrument axis relative to a target axis. The method also comprises establishing, by the processor, a haptic boundary associated with the instrument based on the determined orientation angle of the instrument axis relative to the target axis. The haptic boundary is configured to constrain the instrument axis from being moved to an angle substantially greater than the current orientation angle.
