説明
<jats:title>Significance</jats:title> <jats:p>The octopus quickly reconfigures its arms to perform highly integrated tasks, such as swimming, walking, and preying. Inspired by such a soft-bodied cephalopod biosystem, we engineer compliant origami robotic arms to achieve multimodal deformations that integrate stretching, folding, omnidirectional bending, and twisting for functions such as grasping and lifting objects by means of precise magnetic actuation. The remote magnetic field control allows distributed actuation of the multiple degree-of-freedom robotic system for complex motions to achieve the aforementioned shape-changing capabilities and functionalities. Origami robotic arms with untethered control are applicable to biomedical devices and morphing mechanisms in environments with limited access.</jats:p>
