Grocery store chain Stop & Shop announced today that it will begin testing driverless grocery vehicles in Boston starting this spring, combining the hype of autonomous delivery cars, cashier-less stores, and meal kits into one experimental pilot. The launch is part of a partnership with San Francisco-based startup Robomart, whose vehicles will cart around Stop & Shop items like produce, convenience items, and meal kits to customers' doorsteps. The electric vehicles will be temperature-controlled to keep produce fresh, and controlled remotely from a Robomart facility. Customers can hail the mini grocery stores via an app, on an interface which feels a lot like calling an Uber. Once the vehicle arrives, customers can unlock the doors, and the items they grab are tracked with RFID and computer vision technology.
