![]() ![]() The new design is able to achieve high degrees of strength and gentleness because of how it distributes force throughout the structure of the gripper. "We've been able to improve the fundamental structure itself, as well as the trajectory of the grippers - meaning the path at which the grippers approach an object when grabbing it." "Our new grippers also use kirigami, but are substantially different, as we learned a great deal from the previous design," says Yaoye Hong, co-author of the paper and a recent Ph.D. The design for the new grippers builds on an earlier generation of flexible, robotic grippers that drew on the art of kirigami, which involves both cutting and folding two-dimensional sheets of material to form three-dimensional shapes. "Our design achieves an excellent balance of these characteristics." "It is difficult to develop a single, soft gripper that is capable of handling ultrasoft, ultrathin, and heavy objects, due to tradeoffs between strength, precision and gentleness," says Jie Yin, corresponding author of a paper on the work and an associate professor of mechanical and aerospace engineering at NC State. ![]()
