A handling device includes a gripping member and a support structure that supports the gripping member. The gripping member includes a flexible, substantially toroidal wall member having an outer wall portion and an inner wall portion that defines an axial passageway through the gripping member. A fluid fills the volume enclosed by the wall member. The support structure includes a drive mechanism that engages the wall member and is constructed and arranged to provide relative axial movement between the inner and outer wall portions. |
