Title: Bin-picking system for randomly positioned objectsApplicant: Adept Technology Inc. (USA)Patent number: US7313464Publication date: 25 December 2007

Abstract: A method for picking up objects randomly arranged in a bin using a robot having a gripper for grasping the objects using prehension feature(s) on the object. The method includes a shaking scheme for rearranging the objects in the bin when no objects are recognized, when no objects are prehensible by the gripper or when the object to be picked up is not reachable by the gripper because, for example, its prehension feature is substantially facing a wall of the bin. The method also includes a criterion for determining that a bin is free of objects to be picked up and a criterion for selecting the object to be picked up first in the bin. The method also provides for a protection mechanism against damage of the objects and the robot when a recognition technique has failed in properly recognizing the object or the prehension feature on the object.

Title: Pneumatic power flexible three-finger pawApplicant: Univ Zhejiang Technology (CN)Patent number: CN101209553Publication date: 2 July 2008

Abstract: The invention provides a pneumatic flexible three-finger gripper, comprising a handle and a rotary disc, three pneumatic flexible grippers are arranged at one side of the rotary disc of a torsion joint uniformly according to the angle of 120°; a pipe joint of the pneumatic flexible grippers are arranged on the rotary disc; the pneumatic flexible grippers are embedded into one side of a constrained steel wire and faces to the rotary axis line of the torsion joint; the other side of the rotary disc is connected with a rotary shaft through a bearing; the rotary shaft is connected with the handle; two pneumatic flexible drivers are bent in round shape and symmetrically and transversely arranged on the rotary disc, one end is fixed on a fixed disc and the pipe interface of the other end is fixed on the rotary disc. The invention has the advantages of simple and reasonable structure, flexible motion, simple control, good application effect and greater implementation value.

Title: Sensor arrangement for use as steering angle sensor, has positioning module for precise relative-positioning of sensor unit at magnetic encoder, where module has centering mechanisms, which partially surround encoderApplicant: Continental Teves Ag & Co Ohg (DE)Patent number: DE102007059362Publication date: 6 June 2008

Abstract: The arrangement has a magnetic encoder and a measured variable-magnetic sensor unit detecting a measured variable directly and indirectly provided by the magnetic encoder. A positioning module is provided for precise relative-positioning of the sensor unit at the magnetic encoder, where the positioning module has centering mechanisms, which partially surround the magnetic encoder. The mechanisms are partially formed in a flexible manner, where the mechanisms are designed as a recess and/or clip and/or gripper-shaped annulus. An independent claim is also included for a method for mounting a sensor arrangement.

Title: Multi-flexible production facility for motor vehicle bodies assembled from several partsApplicant: Thyssenkrupp Drauz Nothelfer G (DE)Patent number: EP1873045Publication date: 2 January 2008

Abstract: The system has exchanging stations provided for supporting and clamping devices, and exchangeable gripper storages provided for a gripper. The stations and the storages are arranged at an outer edge of components of rotary tables, operating robots, the exchangeable gripper storages and component storages. The components form a device garden, and the station and the storage are loaded with the supporting and clamping devices and the grippers from outside.

Title: Flexible payload module with inflatable grippersInventor: US Navy (USA)Patent number: US7299925Publication date: 27 November 2007

Abstract: A module for a payload that utilizes individual grippers in which each fill to a conical shape from an interior wall of the module toward a payload in the module. The shape of the grippers provides a holding strength on and lateral stability for the payload. The angle of the conical shape transfers the axial force of the payload into a tensional load on the gripper where it has comparatively greater strength. The conical shape of each gripper allows for more complete capture of a payload in that the grippers fill voids around the payload. Since there are more contact points with the grippers and the payload, the contact force required for an adequate capture can be spread out.

Title: Expandable finger gripperInventor: Gimatic SpaPatent number: JP2007290118Publication date: 8 November 2007

Abstract: Problem to be solved: to provide a pneumatic outer expandable finger gripper capable of safely gripping a case and an object with a small dimension and/or thickness on or near a plane or a separate fixing element.

Solution: this pneumatic control finger gripper comprises a supporting body forming a space, a stationary shaft bar expanding in the space and fixed to an adjacent part of the body from a tip of the body, and a compression disc coupled to the stationary shaft. The pneumatic control piston is guided along the shaft bar, and moves in the space relative to the compression disc between an inactive position at a certain distance from the compression disc and a forward active position near the compression disc. A flexible gripper element is mounted between the compression disc and the control piston and moves between a contracted position and an expanded position according to the movement of the control piston between the inactive position and the active position of the compression disc.
