Oh, how quickly technology evolves.

In the video below, robots of numerous shapes and sizes compete against each other in rounds of soccer during the "RoboCup World Championship," held in Istanbul.

The goal of these games, promoters said, is to one day create robotic intelligence smart enough and fast enough to one day outstrip humans on the field.

From the looks of it, they're a long way off, but it might not be that much longer before technology evolves once again in ways nobody can predict.

This video is from the BBC, broadcast Monday, July 11, 2011.
