Supermarket giant Kroger took another step to bolster its online grocery and delivery business, this time with a partnership with driverless car company Nuro to deliver groceries with its vehicles. The news follows Kroger’s recent investment in Ocado, a British online grocer that Kroger plans to use to develop automated warehouses in the U.S. And in May Kroger bought meal kit company Home Chef. With Nuro, Kroger plans to offer customers the option to place same-day delivery orders through its ClickList ordering system and the Nuro app. A fleet of autonomous vehicles will then deliver the orders. “Unmanned delivery will be a game-changer for local commerce, and together with Kroger, we’re thrilled to test this new delivery experience to bring grocery customers new levels of convenience and value,” said Dave Ferguson, Nuro’s co-founder, in a statement. Kroger, which has 2,800 stores in 35 states, hasn’t announced the details but will start with a pilot program of the service.
