Abstract:
A mechanical finger has a base adapted to be connected to an actuator for being displaced in at least one degree of actuation, and has two or more phalanges. A first phalanx is rotationally connected at a proximal end to the base, and a second phalanx is rotationally connected at a proximal end to a distal end of the first phalanx. A transmission linkage providing at least one rotational degree of freedom (DOF) between the base and a distal-most one of the phalanges. Passive rotational DOF joints are between the phalanges, between the base and the first phalanx, and in the transmission linkage, whereby the mechanical finger has a passive state of actuation in which the base, the at least two phalanges and the transmission linkage remain in a constant orientation relative to one another through displacement of the base caused by the actuator absent a contact of one of the phalanges with an object, and a grasping state of actuation in which a contact of at least one of the phalanges with an object causes a variation of the orientation of at least one of the phalanges relative to the base through displacement of the base caused by the actuator.
Abstract:
Die vorliegende Erfindung betrifft eine Greifvorrichtung (1), die insbesondere als Effektor für einen Industrieroboter vorgesehen ist und erste (10) und zweite (20) Klemmbacken umfasst, die relativ aufeinander zu beweglich eingerichtet sind, um ein Werkstück zu greifen. Dabei ist die erste Klemmbacke (10) mit einem Federvorsprung (11) versehen und die zweite Klemmbacke (20) mit einer entsprechenden Nut (21), die den Federvorsprung (11) im zueinander bewegten Zustand der Klemmbacken (10, 20) zumindest teilweise aufnimmt, um ein unbeabsichtigtes Einführen von Gegenständen bzw. Körperteilen in den Raum zwischen den Klemmbacken zu verhindern.
Abstract:
Gripping device (4) and robot arm (2) to which such a gripping device (4) is attached. The gripping device (4) consists of a housing (6) and two gripping finger sockets (9,10) which can be displaced linearly with respect thereto. Each gripping finger socket (9, 10) is provided with an electric or pneumatic coupling by means of which various gripping fingers (17, 27, 37) can be connected. A rotating drive (13) is present between the gripping finger sockets (9, 10) on which a tool can be placed for releasing or attaching a fastening means, such as a bolt. By means of this relatively simple construction, weights of several hundreds kilos can be lifted and positioned accurately, for example in a processing machine.
Abstract:
A chemical (coating and reduction)/mechanical/electrical treatment of ion-exchange materials (preferably ion-exchange membranes) to convert them to artificial muscles. The figure is a perspective view of an actuator of the invention showing the treated membrane actuator (A) with electrodes (25 and 26) placed at one end of the membrane, the electrodes being further attached to a power source (35). Artificial muscles created by the inventive method are capable of undergoing electrically-controllable large deformations resembling the behavior of biological muscles. A typical flap muscle of 0.2 - 0.4 mm thickness, 2 - 5 mm width and 20 mm length manufactured by the inventive process can achieve a completely reversible maximum deflection of 12 - 15 mm under a maximum voltage of 2.0 - 2.5 volts.
Abstract:
A robotic transport system including a drive section connected to a frame, an articulated arm operably coupled to the drive section providing the articulated arm with arm motion in at least one axis of motion moving at least a portion of the articulated arm in a collaborative space, corresponding to the frame, from a first location to another different location in the collaborative space, the articulated arm having an end effector with a workpiece grip having workpiece engagement members engaging and holding a workpiece during workpiece transport, by the arm motion in the at least one axis of motion, wherein at least one of the workpiece engagement members is frangible compliant, having a frangible compliant coupling between a distal portion of the at least one of the workpiece engagement members and a base portion of the end effector from which the at least one of the workpiece engagement members depends.
Abstract:
Die Erfindung betrifft eine Greif- oder Spannvorrichtung zum Greifen oder Spannen von Gegenständen, mit wenigstens einem von einem Antrieb antreibbaren Stellglied, mit wenigstens einer Backe, und mit einem zwischen dem Stellglied und die Backe vorgesehenen Getriebe, wobei die vom Antrieb erzeugte Kraft wenigstens über ein am Getriebe und/oder am Spannmittel vorgesehenes oder dadurch gebildetes Kraftübertragungselement hin zum Gegenstand übertragen wird, wobei das Kraftübertragungselement einen Kraftleitabschnitt umfasst, wobei zwischen dem Kraftleitabschnitt und dem Kraftübertragungselement ein eine elastische Nachgiebigkeit in Kraftübertragungsrichtung zulassendes Dämpfungselement vorgesehen ist.
Abstract:
Disclosed is a tape dispensing machine for manufacturing a photovoltaic module, and a method of manufacturing a photovoltaic module with a tape dispensing machine. The tape dispensing machine comprises a gripper (125) and a sensor (305) within the gripper, wherein the sensor is configured to detect a first end of a tape (110) within the gripper. The gripper moves relative to the photovoltaic module if the sensor detects the first end of the tape within the gripper.
Abstract:
The invention concerns a prehensile and/or fastening device (2) containing a first (4) and a second (6) prehensile element capable of motion with respect to one another, these first and second elements being entirely constructed of a single block of shape memory material. The invention also relates to a construction process for a shape memory material. 00000
