Robots are taking over fast-food kitchens. See how chains are using automation to make chips, salads, burgers, and fries.

• Restaurants are increasingly using robots to handle mundane human tasks amid rising labor costs.
• Chipotle, White Castle, and Sweetgreen are using robots to prepare salads, fries, and chips.
•  A fully automated burger restaurant debuts this month in Southern California.

Restaurant automation is moving to the back of the house, where robots can be found flipping burgers, cooking fries, and assembling mega-size salads and bowls.
