The robots of Black Friday

Between the lines: On top of the more than 15 million Americans who work in retail year-round, companies routinely hire hundreds of thousands of temporary workers to staff stores and warehouses during big shopping days like Black Friday and Cyber Monday.

• The development of more — and smarter — retail robots puts those jobs at risk.

Piaggio is marketing the robot as a seamless way to lug your groceries or shopping bags around a city. But the company will have to find other uses for the bot to make money off of it, analysts tell AP.

• It's not clear how big the market is for a super-expensive grocery-carrying robot, but the machine could potentially be used to move inventory around in a warehouse or medical supplies in a hospital.

The big picture: This new bot joins dozens of others in the retail industry.

• Tally, a robot developed by Silicon Valley's Simbe Robotics, is already starting to pop up in store aisles.
