Dennis Hong, a robotics engineer at Virginia Tech, said research into "soft robotics" was part of a wider trend towards designing more flexible and innovative machines, such as his own "Whole Skin Locomotion" (WSL) robotic mechanism.
Last month DARPA, the U.S. Defense Department's research agency, invited proposals from robotics experts to build a "chemical robot" made from soft, flexible materials and capable of squeezing through gaps smaller than its regular dimensions.
