Methods and apparatus for grasping and moving workpieces are disclosed. A
device in accordance an exemplary embodiment of the present invention
comprises a disk including an outer edge. The disk has a generally planar
resting shape in which the disk has a first diameter and a first edge
length. A apparatus for holding the disk in a folded shape in which the
disk defines a cavity is also provided. In a preferred embodiment, the
disk is in an unstretched state while the disk is assuming the folded
shape so that the disk may assume the resting shape by unfolding without
unstretching. Also in a preferred embodiment, the disk has a second
diameter and a second edge length while the disk is assuming the folded
shape, where the second diameter is smaller than the first diameter and
the second edge length is substantially equal to the first edge length.
