So, we might be one step closer to the T1000.
The robots created aren't that good at shapeshifting - or remotely humanoid - but they can switch between soft and squishy and rigid - based off of temperature. Of course, it's a DARPA (military) project, so one could envision listening devices squeezing into cracks. Or bombs. Or robot tentacles squeezing into small spaces to defuse IEDs without disturbing their surroundings.
The new robots might also be useful in surgery, search and rescue and even, if the price comes down far enough, home repair and maintenance.
Of course, they'll also be put to other uses...I'll leave that to the imagination of my adult readers.
