Selective Motion Control of a Novel Magnetic-Driven Minirobot With Targeted Drug Sustained-Release Function

In this article, we propose a novel magnetic-actuated multimodule drug sustained-release minirobot (DSM) manipulated by an external rotating electromagnetic field. The structure of the DSM is mainly divided into three parts: 1) a shell; 2) an internal propeller; and 3) a drug chamber. The shell can effectively protect the intestinal tract and reduce the various resistances during the work; the bui...
