a high load capacity advanced wheels based on origami featured in Science Robotics cover

Transformable wheels based on membrane origami have the potential for large shape variation, high weight-to-payload ratio, and simple fabrication. However, existing membrane origami wheels have limited load-bearing capacity. By introducing a wireframe design rule that accommodates thick membranes, Lee et al. have developed a high payload membrane origami wheel capable of bearing more than a 10-kN load. The load-bearing property of the wheel design was validated in a passenger vehicle field test.
