R2D2 and C3PO, the fictional robots in Star Wars (pictured) made an impression with their human-like personas. 30 years later, here's a look at the very latest in robotics:
A robot camel jockey(1) won an inventors' prize. The Ripsaw(2) unmanned tank can plow through small buildings. Korea has developed 'emotional' robots(3). A robotic cockroach fooled other roaches into thinking it was one of them. The WAO-1 is billed as a face-massaging robot. The military has developed a robotic spy bird to keep an eye on things. And Honda's Asimo, an autonomous robot, is now in its 2nd generation.
