The octopus has attracted widespread attention owing to its unique underwater movement and its ability to escape with inkjets, which also promoted the development of underwater bionic robots. This study introduces a magnetic octopus robot (MOR) 3D printed with PA6/NdFeB composite material, which has good magnetic responsiveness and rigidity to cope with complex environments. The MOR can roll and rotate through complex terrain and passages because of its eight-claw structure. It also has amphibious locomotion and can pass through narrow gaps of 37.5% of its height by deformation. In addition, the MOR can not only clamp, transport, and release solids but also liquids by adding silicone hollow spheres, which indicates the potential of the MOR to be used in medical applications for transporting solid or liquid drugs. This research will help broaden the application prospects of magnetron robots in the field of medical drug transportation.

受 Octopus 启发的 3D 打印磁性仿生机器人，用于药物运输。


章鱼因其独特的水下运动和喷墨打印机逃逸的能力而受到广泛关注，这也促进了水下仿生机器人的发展。本研究介绍了一种用 PA6/NdFeB 复合材料 3D 打印的磁性章鱼机器人 （MOR），该机器人具有良好的磁响应性和刚度，可应对复杂环境。由于其八爪结构，MOR 可以在复杂的地形和通道中滚动和旋转。它还具有两栖运动能力，可以通过变形穿过其高度 37.5% 的狭窄间隙。此外，MOR 不仅可以夹住、运输和释放固体，还可以通过添加硅胶空心球体来释放液体，这表明 MOR 具有用于医疗应用以运输固体或液体药物的潜力。这项研究将有助于拓宽磁控管机器人在医疗药品运输领域的应用前景。
