White Castle will deliver some of its Uber Eats orders using Coco Robotics delivery bots in Chicago, Coco announced in a Monday press release. 

The robots and Uber Eats systems are integrated with White Castle’s point-of-sale system through Checkmate, which provides the brand with updates on delivery status. 

Coco has been working with Uber Eats to deliver in select cities, including Los Angeles, since last year, and has been working with both Uber Eats and DoorDash in Chicago. The robotics firm said its operations in the Windy City have been an important proving ground for its technology.

White Castle said the robots could speed up throughput at restaurants by eliminating some of the operational complexities of third-party delivery — namely handing orders off to delivery drivers, whose vehicles may impede other customers.

Chicago White Castle delivery customers may be paired directly with a Coco robot through the Uber Eats app, without additional fees or steps, according to the press release.
