Software & Middleware

Zenoh

Zenoh is a high-performance publish-subscribe and query protocol from the Eclipse Foundation, developed by ZettaScale, that unifies data in motion and data at rest under one API and routes efficiently across LANs, WANs, and constrained links. It was adopted as an alternative ROS 2 middleware through rmw_zenoh, addressing long-standing DDS pain points such as discovery storms and unreliable behavior over Wi-Fi.

Why it matters for physical AI

Fleet-scale robotics needs transport that spans robot, edge, and cloud without brittle network tuning, and Zenoh's rise inside ROS 2 reflects how deployment realities are reshaping core robot software infrastructure.
