Drugs may one day be delivered by ROBOTS we swallow

Drugs could be delivered by microscopic, shape-shifting robots you swallow in the future, scientists believe. Researchers have created the tiny gadgets, which are around 5mm in length and can navigate the narrow channels of the human body. The tiny robots, developed by Swiss researchers, even change shape and speed as they travel through bendy blood vessels and thick bodily fluids. Drugs may one day be delivered by microscopic robots (pictured) we swallow. When tested in the lab, the robot adapted to squeeze through narrow tubes.
