Terminator-style robot can survive being STABBED

Sci-fi fans will know the Terminator was only a ruthless killing machine because of its effortless ability to heal itself after damage. Now, engineers at Cornell University in New York may be well on their way to recreating this remarkable self-healing ability. The experts have created a robot capable of detecting when and where it has been damaged and then restoring itself on the spot. The small soft robot, which resembles a four-legged starfish, uses light to detect changes on its surface that are created by cuts. For self-healing to work, the robot must be able to identify that there is something that needs to be fixed.
