Bionics is the inspiration resource of state-of-the-art science and technique. The chameleon can capture prey by great distances with the assistance of its highly stretchable and ballistic tongue. Inspired by this biological teacher, here we demonstrate the fabrication of flexible electromagnetic manipulators. As-prepared flexible electromagnetic manipulator can reach maximum velocity of 8.1m/s and acceleration of 627m/s2 respectively at an applied voltage of 360V. The working mechanism of this flexible electromagnetic manipulator has been studied based on the Maxwell and Abaqus simulation. Diverse parameters, including the length of magnetic tube (the cylindrical magnet) and the whole manipulators and applied voltage values, have been considered to tune the ejecting performances of the manipulators. Furthermore, flexible electromagnetic manipulators can be upgraded to capture various objects by attaching a mechanical force triggered gripper to their top pads. With this design, the velocity of gripper can be significantly improved(the maximum velocity of this is 8.1m/s. However, the soft gripper in the previous research does not have the characteristics of fast movement ), thus making it possible to get objects without approaching them, in another word, we can catch objects even though they are far away from us ,which provide a possibility of long-distance capture.We believe this kind of bio-inspired fabrication is a powerful strategy to design and synthesize flexible even stretchable manipulators, extending the boundaries of conventional manipulators for soft robots.
