In atypical industrial settings, soft grippers needed to adjust different object shapes. Existing grabbers typically accommodated only single-curvature, fixed-stiffness objects, restricting their stability and usability. This study presents a design for finger featuring multi-curvature, incorporating wedge actuator alongside two variable stiffness units (VSUs) inspired by snake scales. By adjusting the high low states of element, local structural was changed, thereby granting gripper capabilities in bending shape control stiffness. A finite element model developed, influence several parameters, including top wall thickness, side transition layer sidewall height on angle tip output force analyzed through an orthogonal experiment. Furthermore, relationship between longitudinal length both studied. Via explicit dynamic analysis, variation VSU under operational vacuum pressure predicted subsequently validated against experimental data, confirming reliability model. The effectiveness adjustment evaluated experiments. Ultimately, two-finger constructed carry out grasping results showed that is capable generating various clamping curvatures, enabling it conform closely objects grips significantly broaden its range.

Abstract Although pneumatic soft crawling robots have made great progress, there are still several difficulties hindering their practical the most important of which is insufficient stiffness and load capacity under large deformations. An inchworm-like robot with deformability proposed in this paper. Bistable composite structures typically smart morphing variable lightweight, good deformations possessing two stable configurations. Instead traditional materials high Young’s modular, robot, consists a stiffness-enhancing hybrid actuator integrating bistable shell for main body bristle feet, has flexibility, By controlling stiffness-enhanced actuator, capable achieving reversing motions like an inchworm. Experimental results show that tip output force deformed trunk was five times larger than single means owns excellent driving performance flexibility. The collapse 100 g less networks actuator. This also demonstrates structure exactly improves robot. periodic bending-flattening motion transformed into unidirectional by installing feet on both sides can perform well environments different angles, heights, surfaces, verified experiments. provides method to improve while maintaining flexibility demonstrating huge practicability field exploration goods transportation.
