Meet 'microTUM' - Tumbling, Magnetic Microbot for Biomedical Injectables

Purdue University's 'microscale magnetic tumbling robot,' or microTUM, is smaller than the head of a pin. A continuously rotating magnetic field propels the microbot in a tumbling motion, which helps the microbot traverse uneven surfaces in both dry and wet environments. The flat, dumbbell-shaped microbot is made of a polymer and has two magnetic ends. The Purdue University team envisions biomedical micro-robots being injected into patients for super-focused drug delivery.
