Leeds: Scientists at the University of Leeds have developed a very small, soft and fibrous (tentacles) robot that can penetrate deep into the human body, especially the lungs, collect samples and deliver medicine.
It is made up of a 'magnetic robot with arms' made of soft cylindrical structures and crawling in a special way like a snake to reach the narrow inner part of the lungs and go deep and do its work.

If this is a strange and mysterious thing, but we want the body to go down to the depths of the human body without causing any harm and to study diseases and cancer there, according to Pietro Veldastry, a professor of robotics at the University of Leeds.
The lungs are currently examined with a thin, flexible tube called a bronchoscope. But due to its size, the use is limited and it cannot go deeper as the passage of human lungs becomes narrower and more complicated. On the other hand, a bronchoscope is inserted into the lungs through the nose and mouth of the patient which causes pain to the patient himself.
The magnetic robot is just two millimeters wide and can be controlled magnetically from the outside. That is why it reaches to the very depths of the lungs and there can be a new revolutionary diagnostic tool for all diseases.
Inside the arm of this robot are very thin magnets that help it move forward. In the future, doctors will be able to note the robot's movements on a display outside and find out the condition of the lungs. However, in the first phase, it has been tested on animals and dead humans. In the next phase, humans will be tested, but this could take five to ten years.
