spiffy1 writes "A group of Japanese electronics corporations, (Mitsubishi, Sumitomo, and Matsushita) have developed a 5mm by 9mm by 6.5mm robot. These robots will be used to inspect and repair power plants without need for shutdown. They can zoom between tiny pipes and wires at the rate of 2mm per second, lift nearly 1 gram, and link up with other robots to accomplish bigger tasks. "
