Gripper system
First Claim
1. A gripper system comprising:
- a pair of jaws operable in a first plane and having a central closure axis, each jaw including a finger member and finger tip member disposed on its distal end; and
a gripper drive assembly for moving said jaws toward and away from each other;
each finger member having a shaped inner contour for accommodating an object to be gripped, each finger tip member including a concave inner surface having angled sections which generally aligns with said shaped inner contour when gripping objects, said inner surface for gripping a range of larger objects and followed by a concave outer surface extending outwardly from the inner concave surface and also having angled sections which generally align with the gripper central closure axis upon closure for gripping a range of smaller objects.

Abstract
A gripper system having a pair of jaws operable in a first plane and having a central closure axis; each jaw including a finger member and finger tip member disposed on its distal end; and a gripper drive assembly for moving the jaws toward and away from each other; each finger member having a shaped inner contour for accommodating an object to be gripped; each finger tip member including an inner surface which generally aligns with the shaped inner contour for gripping a range of larger objects and an outer surface which generally aligns with the gripper central closure axis upon closure for gripping a range of smaller objects. Alternatively, each finger tip member may include a forcep element extending transversely to said plane.
