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.
Researchers from iRobot and the University of Chicago discussed their palm-sized soft robot, known as a chemical robot, or chembot, at the IEEE/RSJ International Conference on Intelligent Robots and Systems yesterday. It's "the first demonstration of a completely soft, mobile robot using jamming as an enabling technology," they write in a paper presented at the conference.
The concept of "jamming skin enabled locomotion" is explained quite nicely in the video. The polymer used for the botâ€™s stretchy skin is off-the-shelf silicone two-part rubber.
By controlling the parts of the blob that "inflate," the researchers can make it roll.
The video shows the project as it was about a year ago. The current stage has a bit different design and is moving toward the ability to include sensors or even connect different blobs together, but those details are sketchy.
When asked about the usefulness of such a bot, iRobot researcher Annan Mozeika promptly answered, "to squeeze into small holes." And who wants to do that? DARPA, of course. End of questions.
