swarm project that really makes us wonder how long humans will be running things on Planet Earth. MIT's own James McLurkin was recently down in Austin, Texas showing off a dozen or so of his hundred (is that even legal?) robots. The group was reportedly able to spread out, clump together, play follow the leader and circle the wagons, all of which were just ploys to distract us from seeing precisely how much they really know. Each of the appropriately-titled SwarmBots featured eight AA batteries, a 1.1-watt speaker, behavior LEDs, a radio, camera and an IR communications system. For those curious, each one cost around $2,000 to build, but Mr. McLurkin suggested that these were a bargain compared to typical research bots. It's all about perspective, baby.
