The Boston Globe describes the efforts of a Japanese-born scientist to develop new technologies for use in surgery. His last project is to build a swimming robot designed to explore the human gastrointestinal tract (GI tract) from esophagus to colon.This 2-centimeter long robot will have a swimming tail to deliver the energy picked from the outside and use it to steer it in the GI tract. It will also be able to send back images to the physicians and to deliver therapy. Coincidentally, the Philadelphia Inquirer is reporting about another medical robot helper able to crawl like an inchworm into your heart.
