Embodiment Construction

[0018] Reference is now made to the drawings, in which the depictions are for purposes of illustrating certain exemplary embodiments only and are not intended to be limiting of the exemplary implementations. Figure 1-9 An embodiment of an adaptive holding device for clamping a workpiece is schematically shown, wherein the holding device comprises a jamming element with a second or more elements for clamping the workpiece. A holding device may be utilized onto an end effector of a robotic arm to controllably grip or otherwise hold or assist in holding to a workpiece to restrain the workpiece at one location or to bring the workpiece to another location. Throughout the embodiments, the same terms and reference numerals are used for the same elements.

[0019] figure 1 An embodiment of an adaptive retention device 10 comprising a controllable electroadhesive element 20 secured to a surface of a jamming element 50 is schematically shown. The jamming element 150 includes a gas i...

Abstract

A device for gripping a workpiece is described, and includes a holder including a base and a conformable jamming element. The conformable jamming element includes an air-impermeable pliable membrane containing filling material including magnetic particles, and is attached to the base. An electroadhesive element and a conformable releasable surface-adhesive element are secured to a surface of the membrane.

Description

technical field [0001] The present invention relates to workholding devices for fixtures, tools, material handling and robotic end effectors. Background technique [0002] Universal grippers for tools, fixtures, and robotic end effectors advantageously utilize holding devices that attach to workpieces of various arbitrary shapes for movement and placement during manufacturing and assembly. Universal grippers can utilize some form of external power source for gripping and release, including vacuum-based suction grippers and anthropomorphic multi-digit grippers for gripping and manipulating workpieces. [0003] Passive universal grips require minimal gripping design and include components that passively adapt to unique workpiece geometries, giving them the ability to grip widely varying workpieces without readjustment. Passive universal grippers may be simple to use and may require minimal visual preprocessing of their environment. However, the ability to grip many different...
