Engineers and scientists have developed proof of concept for a robot that can reach some of the smallest bronchial tubes in the lungs to take tissue samples or deliver cancer therapy.

Known as a magnetic tentacle robot, it measures just 2 millimeters in diameter, about twice the size of the tip of a ballpoint pen.
Magnets on the outside of the patient will be used to guide …
