A University of California, Berkeley (www.berkeley.edu) team, headed by physics professor Alex Zetti, has built a 500 nm electric motor—the world's smallest—from carbon nanotubes and silicon. The motor is the first device that allows external wires and a rotor. In this case, the rotor is between 100 to 300 nm long, while the carbon nanotube shaft to which it is attached is only a few atoms across, perhaps 5 to 10 nm, the team says. Applications might include optical switching, or the spinning rotor could be used to mix liquids in microfluidic devices, the team adds.
Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
