A company named Kiva Systems has developed robots that operate many warehouse functions currently performed by humans. The company has combined three technologies - WiFi, digital cameras, and low-cost servers - into these robots which allows them to perform order fulfillment functions. The servers work in real-time, receiving orders, immediately dispatching robots to bring the required pods to the worker fulfilling the order, and then returning the pods to their storage locations. The robots receive their orders wirelessly, while using cameras to read navigational barcode stickers on the warehouse floor.
The techology has already proven very promising. Kiva lists Walgreens, Gap and Zappos as some of their largest customers, with Walgreens planning to have 1,000 bots in its warehouses by next summer. Zappos' Vice President of Fulfillment is quoted in the article as saying, "It's exceeded all of our expectations, doubling the productivity of our pickers and cutting our energy costs in half." So not only are these robots more efficient than humans, but because they don't need air conditioning or much lighting, they also save on warehouse energy costs. Maybe it's time we humans start watching our backs!
