Kroger to Use Robot Cars for Grocery Deliveries in Arizona Grocery chain Kroger and autonomous vehicle startup Nuro have launched a driverless delivery service. The two companies, which announced their partnership in June, debuted the service in Scottsdale, Arizona. To start out, only one store is involved in the experiment. Grocery orders can be scheduled for same-day or next-day delivery. The delivery fee is $5.95 per order and there is no minimum order amount. Groceries will be delivered via Nuro’s fleet of self-driving Toyota Prius and Nissan Leaf vehicles. Each car will have a safety driver behind the wheel.
