Robots are taking over factories around the world.

The International Federation of Robots tracks the growth in usage, production, and trade in robots, and the numbers have grown at a tantalizing rate. Robot sales jumped by 38 percent in 2011, and the worldwide stock of robots is estimated to be in the range of 1,153,000 - 1,400,000 units — up from a minimum stock of 1,021,000 units in 2009.

South Korea lead the way in robot density in 2011, with 347 robots per 10,000 workers in the manufacturing industry. What's more impressive is the tremendous spike in robot density; South Korea had 287 robots per 10,000 workers in 2010.

Here are the countries where robots are taking over manufacturing:

The automotive industry has an even greater robot density.

Although three of the top four countries for robot densities stagnated from 2010-2011, developing countries like China, Thailand and Brazil saw big gains in robotic density.
