Robot Can Crawl Through Human Body

Moving reality a step closer to "Fantastic Voyage," researchers at the Technion-Israel Institute of Technology have developed a micro robot that can crawl through the human body.

“Micro robots are being developed in many research centers, but this is the first time we’ve been able to create one that can crawl through the body,” says Professor Moshe Shoham of the Technion Faculty of Mechanical Engineering, who headed the university’s research team. Prof. Shoham is the developer of the FDA-approved SpineAssist spine-surgery robot.

The robot is propelled by micro legs, a mechanism especially adapted to the movements of a tiny body through water. It is only a millimeter in diameter and 14 millimeters long, fitting on the tip of a finger, so it can get into the body’s smallest areas. It is powered by either actuation through magnetic force located outside the body, or through an on-board actuation system. Made of silicone and metal, it can be made completely biocompatible, so it could remain in the body much as a stent placed in arteries does.

“In the future, we hope the robot will be able to travel through a blood vessel, the digestive tract or the lungs, delivering targeted medicines to specific locations, clearing blockages, performing biopsies, or placed inside a shunt to drain body fluids from clogged areas,” Shoham explains.

The development has been presented at scientific conferences where it has aroused great interest. Professor Menashe Zaaroor and research engineer Oded Salomon also participated in the research.

However, Prof.Shoham explains that a final product will not be ready for several years. A small enough camera needs to be developed, and an actuation device that will steer the robot once inside the body needs to be perfected. Animal trials are being performed, but human trials are about two years away.

The Technion-Israel Institute of Technology is Israel's leading science and technology university.  Home to the country's winners of the Nobel Prize in science, it commands a worldwide reputation for its pioneering work in nanotechnology, computer science, biotechnology, water-resource management, materials engineering, aerospace and medicine.  The majority of the founders and managers of Israel's high-tech companies are alumni. Based in New York City, the American Technion Society (ATS) is the leading American organization supporting higher education in Israel, with offices around the country.
