Serve Robotics has raised $40 million in its IPO toward bringing deliveries for partners to more cities across the U.S.

The process has taken four years to complete, but Matternet is leading the industry as the first to be certified by the FAA.

PUDU D1 is the first quadruped, last-mile delivery robot from the company. It uses all of the core technology from its wheeled siblings.

On-demand robot delivery is now available in Pleasanton, CA at the Lucky supermarket flagship store
