Uber ditched its work on developing self-driving cars in 2020 but in recent weeks the company has signaled that it’s still interested in exploring elements of autonomous technology for its services.

This week, for example, it’s emerged that Serve Robotics is planning to expand its tie-up with Uber Eats to deploy 2,000 of its diminutive delivery robots in locations across the U.S. and Canada from later this year or early next, TechCrunch reported.

The partnership currently involves a small-scale delivery service in a small part of Los Angeles that started last year, with more than 200 restaurants now using the wheel-based bot to deliver meals to hungry customers between the hours of 10 a.m. and 9 p.m.

It’s not yet clear which locations will host the new meal-delivery robots, though San Jose, Dallas, and Vancouver are reportedly prime candidates.
