The soft NdFeB/Ecoflex composites for soft robot with a considerable magnetostimulated shrinkability

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)...
