Why the future of retailing involves robots, drones and driverless cars

Some, like Wal-Mart and Best Buy, have pushed the idea of having online purchases shipped to and from nearby stores, where they can be picked up. Others, including Amazon, have suggested consumers pick up their purchases from storage lockers scattered throughout the community, not unlike Canada Post’s proposal. But perhaps the best indication of the immensity of the challenge is Amazon’s scheme to muster an army of unmanned drones to deliver its arrow-adorned boxes—a moon shot if there ever was one. Not to be outdone, Google has dispatched the man behind its Android mobile software to build a fleet of robots, leading some to speculate we’ll one day see Google’s driverless cars delivering parcels.
