How Amazon Triggered a Robot Arms Race - Bloomberg

Warehouse different

"Those are Kiva robots, once the marvel of warehouses everywhere. Amazon whipped out its wallet and threw down $775 million to purchase these robot legions in 2012. The acquisition effectively gave Jeff Bezos, its 52-year-old chief executive, command of an entire industry. He decided to use the robots for Amazon and Amazon alone, ending the sale of Kiva's products to warehouse operators and retailers that had come to rely on them. As contracts expired, they had to find other options to keep up with an ever-increasing consumer need for speed. The only problem was that there were no other options. Kiva was pretty much it. 
It's taken four years, but a handful of startups are finally ready to replace Kiva and equip the world's warehouses with new robotics. Amazon's Kiva bots proved this kind of automation is more efficient than an all-human workforce. The new robots being rolled out look different, partly because the industry is still experimenting and partly because of patent issues. Some focus on picking items off shelves, others zoom around with touch screens. All are aimed at saving retailers money as they race to get their wares to your doorstep as quickly as possible."
