Chembot being developed by iRobot

iRobot Corporation has been developing a bot that can shift from one shape to another. IEEE Spectrum carries an article on this new technology titled, iRobot's Shape-Shifting Blob 'Bot Takes Its First Steps.

This is by far one of the coolest and weirdest robot prototypes we at IEEE Spectrum have ever seen.
Meet iRobot's soft, shape-shifting robot blob. It rolls around and changes shape, and it will be able to squeeze through tiny cracks in a wall when the project is finished.
