7-Eleven is quietly testing self-driving robots to deliver Slurpees and Big Bite Hot Dogs in Los Angeles. Here's how it works.

• 7-Eleven is testing autonomous robot deliveries in the Los Angeles area. 
• The AI-powered robots are programmed to slow down on rough terrain to ensure spill-free Slurpees.
• The convenience-store chain is using robots by Uber-backed Serve Robotics. 

In West Hollywood, California, consumers don't have to fight local traffic when craving an ice-cold Slurpee.

All they have to do is hail a robot.
