Abstract
Surgical robots and other telepresence systems have enhanced grip actuation for manipulating tissues and objects with small sizes. A master/slave system is used in which an error signal or gain is artificially altered when grip members are near a closed configuration.

48. In a medical robotic system, a handle coupled to first and second end effector elements through a processor so as to manipulate a separation between the first and second end effector elements through operator manipulation of the handle, the handle comprising:
-
first and second grip elements coupled together at conjoining ends of the first and second grip elements and defining a separation between free ends of the first and second grip elements; and at least one spring coupled to at least one of the first and second grip elements, wherein the at least one spring exhibits a first spring constant while the separation exceeds a separation transition point that corresponds to the free end of the first end effector element making contact with the free end of the second end effector element and exhibits a second spring constant greater than the first spring constant when the separation is less than the separation transition point. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55)
