| 摘要 | A universal gripper includes a set of pivoting fingers on pins mounted uniformly around a fixed ring. The fingers attached by springs to a movable ring are able to rotate inward, toward the center, until they meet an object and stop. Multiple universal grippers could be stacked to allow for different contours throughout objects and facilitate the pivoting fingers conforming and wrapping around a centerline of the objects. Once the universal gripper fingers are in contact with the surface of the object, they stop moving and springs attached to the fingers elongate as the movable ring continues to move over its full range of motion. An alignment tool can be used for staging and acquiring objects in a repeatable and consistent manner. | ||||||
