The result is that 75% of Amazon deliveries are now assisted in some way by robots. One of the newest bots assisting in that effort is "Vulcan". Unveiled in May, Vulcan has two arms, cameras, suction cups and a sense of "touch". Amazon says it's capable of self-improving over time, which isn't in the least bit unnerving. Not. At. All.

Amazon is also looking to use a new generation of bipedal robots to help with the so-called "last-mile" of the delivery chain, where the process typically slows down, becoming far less direct and efficient.

The robotic workers operate in over 300 Amazon warehouses across the world, creating an ever-expanding automated delivery network. More than 75% of Amazon's global deliveries are assisted in some way by robot automation, according to a report by the Wall Street Journal.
