Aristos Mazer sends word of research out of iRobot on a "chembot," or morphing blob robot, that looks like dough and moves by shifting its sides from solid-like to liquid-like states. This will allow it, in theory and after lots of refinement, to pass through cracks by squeezing. iRobot calls the new technique "jamming." The research project was funded by DARPA. The video clearly shows the early stage the work is in, but when you think about it the possibilities are a little unsettling.
