This is the smallest robot in the world till date that does not require any external or additional aid in order to crawl through the smallest of diameters.
Researchers hope this could lead to breakthroughs in diagnostic and therapeutic procedures.
A group of scientists built this robot which is 1 millimeter in width and 4 millimeter in length and uses an external source of energy.
The micro robot will be able to enter through the human vascular system, the spinal chord and other organs that are now considered out of reach for doctors.
Present technologies allow doctors to insert small objects which carry medicine, cameras and other devices into the body.
With this robot doctors would be able to access parts of the human body with more ease than current methods allow. - DDNEWS India
