Abstract
The present invention will provide a device in which the gripping action is achieved by a compliant membrane manipulated by electromagnetic forces. The gripping force provided by the present invention is best suited for delicate objects, as it gently applies the gripping force necessary for displacement. This is accomplished through a chamber, a membrane, a plunger attached to the membrane, and a solenoid configured to manipulate the plunger, and thus, the membrane.
Claims19
An electromagnetic gripping device, comprising:
- a solenoid comprising a conductive material, wherein said solenoid generates an electromagnetic field when current is applied;
- a deformable membrane;
- and
- a plunger attached to said deformable membrane and positioned within said electromagnetic field, said plunger further comprising a ferromagnetic, ferrimagnetic, or magnetic material configured to interact with said electromagnetic field;
- a chamber, wherein said deformable membrane is positioned adjacent to said chamber, said chamber configured to provide structural support to the device;
