A closer look
Imagine a pile of metallic sand that suddenly decides to stand up and form a wrench. Swarm robotics pushes us closer to programmable matter, where thousands of coin-sized robots—like MIT's famous Kilobots—communicate via infrared light to act as a single shifting organism. They have no central brain; instead, they use biological algorithms similar to slime molds to mathematically vote on shapes, collectively bridging gaps or surrounding objects. It is the horrifyingly brilliant prequel to the T-1000 Terminator.
