Created by: iRobot and the University of Chicago
Size: Prototypes run from the size of a ping pong ball to basketball size
Purpose: Shape-shift and fit through small spaces

The makers of the Roomba and Scooba took on a grant from the U.S. Army and the Defense Dept. to create a shape-shifting robot. The result is the Chembot. It moves by inflating and deflating as well as by pushing certain sections out and jumping along. Still in the realm of technology research, iRobot will not produce these soon. It could be a long while before we see a shape-shifting robot squeeze through a crack in the door.
