Energy stored in the folding of creases and in the bending of panels allows for controlled, reversible, and complex motions using fewer actuators.

University of Pennsylvania (Penn) researchers developed a centimeter-scale quadruped robot inspired by origami.

Based on curved-crease origami, the single-motor CurveQuad can self-fold and unfold, crawl, and steer.

The robot can perform controlled, reversible, and complex motions with fewer actuators due to the energy stored in its creases and bends.

CurveQuad's scalable design requires only a few flat sheets of material folded into a three-dimensional shape, with electronics, actuators, and computation fully embedded.

Said Penn's Cynthia Sung, "Since it is simple and thus relatively cheap, we imagine that similar designs can be made in the future for rapid deployment of robotic swarms, which could be produced for dollars or potentially even cents per robot."
