Marble and Yelp Eat24 start robot food delivery in San Francisco

Rules governing the use of food delivery robots remain to be seen across the US. But major food businesses are investigating the possibilities already. In the latest deal, Yelp Eat24 has begun testing delivery by robot in partnership with Marble in select San Francisco neighborhoods. TechCrunch spied Marble's delivery robots, stickered with a Yelp Eat24 logo, earlier this month. But the companies announced their robot delivery service officially today.
