变形是许多动物进化出的一种生存智慧，以保护自己和更容易捕食食物。软磁复合材料提供了一种不受束缚的策略，允许软机器人变形和移动。然而，这是巨大的挑战，磁性软机器人在受限的环境中，如狭缝小于其尺寸的挤压，以及携带和释放所需的物品。在这里，我们展示了一个磁性空心软机器人（MHSR）组成的软NdFeB/Ecoflex复合材料，它具有相当大的磁刺激收缩。MHSR可以通过其高度的五分之一的狭缝和其高度的一半的通道而不会造成结构损坏。值得注意的是，MHSR可以携带大约20个弹丸，通过只有其高度一半的狭缝挤压，然后主动释放它们。我们设计的可变形磁性软机器人可以通过微小的缝隙或通道进行挤压，为软机器人主动适应受限环境的发展奠定了基础。
Shape deformation is a survival wisdom that many animals have evolved to protect themselves and prey foods easier. Soft magnetic composites provided an untethered strategy to allow the soft robots deform and move. However, it is great challenges for magnetic soft robots to squeeze in constrained environment, such as slits smaller than their sizes, as well as carry and release desired items. Here we demonstrate a magnetic hollow soft robot (MHSR) composed of soft NdFeB/Ecoflex composites, which has a considerable magnetostimulated shrinkability. The MHSR can squeeze through slits one fifth of its height and channels half of its height without structural damage. Notably, the MHSR can carry about twenty pellets to squeeze through a slit only half of its height, and then actively release them. Our design for deformable magnetic soft robots to squeeze through small slits or channels have laid a foundation for the development of soft robots to actively adapt to the constrained environment.
