In a significant move aimed at expanding the reach of autonomous robotics beyond delivery, Serve Robotics, a leading US-based sidewalk delivery robot company, has officially announced the acquisition of Diligent Robotics, a startup specializing in healthcare robots. The deal, valued at $29 million in stock with an additional $5.3 million contingent earn-out, is expected to close in Q1 2026.
This merger positions Serve Robotics to enter the healthcare robotics market, enabling its robots to assist in indoor environments like hospitals, clinics, and potentially other institutional facilities.
About Serve Robotics
Serve Robotics began as a spin-off from Uber in 2021, quickly establishing itself in autonomous delivery solutions. The company’s robots are primarily designed to navigate sidewalks and urban environments, delivering food, groceries, and packages safely using a combination of AI, machine learning, and advanced sensor systems.
Key Highlights:
- Operates across multiple US cities with hundreds of delivery robots.
- Focuses on “Physical AI”, integrating artificial intelligence into robots that interact with the real world.
- Previously acquired smaller startups such as Vayu Robotics and Phantom Auto, enhancing their autonomous platform and operational efficiency.
Serve Robotics’ leadership believes the addition of Diligent Robotics will allow the company to extend its AI-powered robots into indoor environments, opening new revenue streams.
About Diligent Robotics
Founded in 2017, Diligent Robotics is best known for its hospital-assist robot, Moxi, which automates repetitive tasks like:
- Delivering lab samples and medications
- Transporting medical supplies
- Assisting healthcare staff with routine operations
Impact So Far:
- Over 25 hospitals in the US are currently using Moxi robots.
- Robots have completed more than 1.25 million autonomous deliveries.
- Diligent Robotics’ mission is to free hospital staff from routine tasks, allowing them to focus more on patient care.
The startup has received multiple rounds of funding from venture capital firms and has been recognized for pioneering AI and robotics in healthcare.
Deal Overview
