Serve Robotics: Autonomous Sidewalk Delivery Robots

Serve Robotics Achieves Level 4 Autonomy in Sidewalk Deliveries

Serve Robotics, originating as a spinout from Uber, is now deploying its latest generation of delivery robots. These robots are designed to execute certain commercial deliveries independently, without the need for direct human control.

This advancement signifies a notable step forward in the field of robotic delivery systems. Specifically, within designated, geofenced operational areas, Serve will no longer depend on remote operators for teleassistance or safety escorts.

A Shift Away From Remote Operation

The majority of companies currently operating in this sector, including Coco and Kiwibot, typically utilize remote operators to oversee autonomous deliveries. These operators are prepared to assume control if a robot encounters difficulties or comes to a halt. Serve’s achievement represents progress in autonomous robotic delivery.

Ali Kashani, co-founder and CEO of Serve, explained to TechCrunch: “The challenge we’ve addressed is that relying on teleoperation for safety necessitates consistently reliable LTE networks and flawless operator performance, both of which are unattainable.”

He further elaborated, “Consider scenarios where a safety concern demands human intervention, but the video feed is delayed or the connection is lost. With Level 4 robots, human involvement isn’t essential for maintaining safety.”

Level 4 Autonomy in Action

Serve initiated the rollout of its next-generation robots in December. The company recently reported completing its first delivery utilizing Level 4 autonomy.

According to the SAE (Society of Automotive Engineers) definition, Level 4 autonomy allows a system to operate independently under specific conditions, eliminating the need for human intervention. Currently, Serve’s robots possess L4 capabilities in select Los Angeles neighborhoods, including Hollywood, where they have been operational since 2018, as stated by Kashani.

“When a robot operates within a Level 4 enabled zone, the remote video transmission is deactivated, and the robot continues its navigation autonomously, without requiring human oversight,” Kashani clarified to TechCrunch. “The robots can request assistance if they encounter unforeseen circumstances. They also activate video during intersection crossings, but for the majority of their operation, they function autonomously.”

The Role of Human Oversight

Until fully autonomous vehicles reach Level 5 capability – operating in all conditions without human input – a range of unpredictable scenarios will inevitably arise. Kashani believes that relying on human operators for these edge cases is sensible from both a safety and commercial standpoint.

Advanced Sensor Technology

Serve’s new robots are equipped with a comprehensive suite of sensors. These include active sensors like ultrasonics and lidar sensors sourced from Ouster, alongside passive sensors such as cameras, to facilitate navigation on busy sidewalks.

The company has developed specific functionalities for its robots, including automatic crash prevention, vehicle collision avoidance, and fail-safe emergency braking. The computational power required for these real-time capabilities is provided by Nvidia’s Jetson platform, specifically designed for robots and autonomous machines.

Future Expansion Plans

Last month, Serve secured a $13 million expanded seed round. These funds will be allocated to accelerate expansion into new customer segments and geographic regions.

Consistent with these objectives, Kashani indicated that Serve’s immediate focus is to deploy its next-generation robots in additional areas, beginning with further expansion within Los Angeles.
