Israelis Design Tiny Robot to Travel Through Small Intestine

The Times of Israel reports: A tiny ingestible robot designed by Israeli scientists may one day have the capacity to slither its way through the small intestine, upgrading the effectiveness of the colonoscopy test.

Created by scientists at Ben-Gurion University of the Negev, the SAW (single actuator wave-like robot) will have the ability to navigate forward and backward through the cramped terrain of the small intestine thanks to its unique wave-like locomotion. It would be able to analyze the digestive tube using a small camera attached to the snake-like robot, according to a report last week on the Live Science website.

“The external shape of the robot is a 2D projection of a rotating helix.The result is a continuously moving wave. We can simply reverse the direction by reversing the direction of rotation of the motor,” explained mechanical engineer David Zarrouk.
