iRobot, the company that invented the Roomba household vacuuming robot, is developing a robot that locomotes by inflating and deflating sections of its outer skin, moving contents inside toward its destination. Kristina Grifantini writes at MIT's Technology Review:
This week at IROS 09 (Intelligent Robots and Systems), iRobot and the University of Chicago unveiled a soft, blobby robot that looks something like an inflating marshmallow.
The new robot, called chembot, changes the shape of its stretchy polymer skin using a technique called "jamming skin enabled locomotion". This means that different sections of the robot inflate or deflate separately; controlling this inflation and deflation enables the robot to move. DARPA, which is funding the project, hopes to use the robot to squeeze into small holes or under doors, which I'm guessing would be used for sophisticated surveillance.
