  "abstract": "A mechanical finger gripper comprising one tool-change interface and four gripper fingers. When the gripper reaches the gripping position, the gripper fingers are closed by the electric actuator. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
