Engineers at the University of Leeds have developed a magnetic tentacle robot to pass through the narrow tubes of the lungs.

Scientists and engineers at the university made a proof of concept for a robotic device that can reach the smallest bronchial tubes to take tissue samples and deliver cancer therapy.

The tentacle robot has a diameter of 2 mm, about twice the size of a ballpoint pen’s tip. Magnets outside a patient’s body guide the tentacle robot into place.
