Chipotle Mexican Grill is testing whether automation can make customers' burrito bowls and salads. It's the second time the burrito chain has publicly announced testing automation at its innovation center. Roughly two-thirds of all Chipotle digital orders are either burrito bowls or salads, according to Chipotle. The Hyphen robot will make burrito bowls and salads for digital orders only. Simultaneously, an employee can assemble digital orders for other items, such as tacos, quesadillas and burritos, on the digital make line.
