  • Haptic device grippers for surgical teleoperation
    Patent number: 8209054
    Abstract: An embodiment of a haptic gripper system includes a slave gripper device, a master gripper device, and a gripper motor controller. The gripper motor controller includes a slave encoder loop, a master encoder loop, and a haptic loop. The haptic loop is configured to receive a slave motor encoder loop output signal and a master motor encoder loop output signal, determine a difference signal between the slave motor encoder loop output signal and the master motor encoder loop output signal representative of a difference between a first relative angular position of a slave gripper motor and a second relative angular position of a master gripper motor, and provide a slave motor control signal to a slave motor control signal input, and provide a master motor control signal to the master motor control signal input.
