From a Wall Street Journal story by Heather Haddon headlined “Sweetgreen Hires Kale-Shooting Robots to Speed Up Service”:

The key to shorter lines and higher profits at one restaurant chain: a salad-making robot.

Fast-casual chain Sweetgreen in May opened its first restaurant staffed by a proprietary robot that shoots kale, cheese and other ingredients down tubes into bowls traveling on a conveyor belt. A handful of employees add finishing touches, such as spiced cashews.

The system can slash the number of workers and time it takes Sweetgreen to make a bowl by more than half, executives said. Eventually, the company intends for salad-making robots to staff all of its new restaurants, working alongside human employees.
