This invention relates to a rigid grasping
manipulator based on Kresling and Waterbomb creases, comprising a Kresling crease
wrist mechanism, a Waterbomb crease finger segment mechanism, and a base. The base is coaxially disposed at the bottom of the Kresling crease
wrist mechanism; the Waterbomb crease finger segments are evenly distributed circumferentially at the bottom of the base. The finger segment mechanism utilizes the three-dimensional design of the peaks and valleys in the Waterbomb crease, replacing the peaks and valleys with rods to achieve bending and grasping at each fingertip. The
wrist mechanism utilizes the torsion characteristic of the Kresling crease, allowing the
manipulator's fingers to bend and twist simultaneously during grasping. By combining origami theory with the three-dimensional design of the mechanism, the
manipulator achieves both grasping and
twisting movements for capturing non-cooperative targets in space. This invention utilizes Waterbomb and Kresling creases to achieve the manipulator's retractability; the wrist and finger parts can be completely retracted, resulting in a smaller space occupied during launch and ensuring convenient transportation. Once the manipulator reaches the designated working track, it can be fully deployed for grasping operations.
