Looking like something Q would give to James Bond for his next adventure, these miniature self-contained robots can move using power from a built in solar cell, while receiving infrared control signals. Three of the tiny legs are used to move the robot, while a fourth is used as a sensor to detect objects and other robots in the swarm.
With the addition of a ASIC (application-specific integrated circuit), the developers claim that groups (swarms?) of the I-Swarm can be used for micromanufacturing, medical procedures, cleaning, or surveillance. I'm sure that last possibility will be of interest to Q.
