  • End effector with centering grip
    Patent number: 7712808
    Abstract: A flat workpiece transport apparatus having a movable arm and an end effector. The end effector is connected to the arm. The end effector has a movable grip for holding a flat workpiece on the end effector. The end effector has a grip actuator operably connected to the movable grip. The grip actuator has more than one actuation members and a resiliently flexible member connecting the more than one actuation members. Each actuation member actuates at least one corresponding grip element of the movable grip to capture or release the workpiece. Flexure of the resiliently flexible member effects movement of at least one of the more than one actuation members for actuation of the at least one corresponding grip element. The resiliently flexible member is sandwiched by substantially rigid portions of the more than one actuation members.
