Scientists have developed miniature gelatinous robots that can crawl through the human body to deliver medicine or diagnose illnesses.

The “gelbot” is powered by little more than temperature changes, and its innovative design, which resembles an inchworm, is one of the most promising concepts in the field of soft robotics, according to Jill Rosen of John Hopkins University.
