The current generation of robots, whether they're the gun-carrying or child-coddling variety, come in all sorts of shapes and sizes to suit their intended purpose. But if research going on at Tufts University comes to fruition, future robots might feature designs that are rather more flexible. Scientists at the school are working on so-called "chemical robots" with no solid parts. Chembots could squeeze under doors, slither through cracks in walls, and even squirm into your orifices, performing internal diagnoses before slowly dissolving away, leaving nothing more than a feeling of creepy violation behind. What about assuming the shape and voice of John Connor's adopted mother? We're hoping that's still a few years off.
