1. A foot of an adhesive gripper for pick-and-place maneuvers, the foot comprising:
a shape memory polymer (SMP) dry adhesive comprising a shape memory polymer and having a front side for the attachment and detachment of objects, the shape memory polymer having a first stiffness;
a soft polymer layer on a back side of the SMP dry adhesive, the soft polymer layer having a second stiffness less than the first stiffness; and
a rigid backing layer attached to the soft polymer layer.
