~250,000 robots are now in use in the United States, the third highest in the world behind Japan and China.
Robotics has revolutionized the world in two distinct phases. The first phase brought electric machines that could perform repetitive tasks but were otherwise useless. Robots such as these were used in car manufacturing and on assembly lines for similar products.
The second phase has started to create industrial robots that don't just perform simple tasks; they absorb data and respond to new information so that they actively improve. While these robots are still predominantly seen in the automotive industry, it won't be long before they affect every type of industry.
