I'm gonna have to read up more on this one. I have a hard time grasping how this is possible:<p>> "Edible robots could be used to deliver food to endangered areas, to deliver medicines in innovative ways to people who have difficulty swallowing or to animals"<p>Given the main anecdote:<p>> "two completely edible robotic teddy bears...when air is injected through dedicated pathways, their heads and arms move."<p>Seems like there's a long way to go here.
