Zenoh is a lightweight, IoT-focused middleware that enables efficient and scalable information sharing across various domains in the applied sciences community. Supply: ZettaScale
While cell robots can bring benefits to various industries, current knowledge distribution services like DDS middleware often struggle to maintain seamless connectivity in Wi-Fi environments, as observed by ZettaScale Expertise Ltd. The France-based firm notes that this approach hampers communication and scalability.
ZettaScale has developed the Zenoh protocol, a cutting-edge solution enabling robust communication in dynamic environments for applications such as autonomous vehicles, IoT devices, and robotics systems. In 2022, ZettaScale emerged from its roots in data-driven decision support (DDS) analysis and growth, specializing in visitor management solutions for the aerospace and military sectors; the company appointed a seasoned chief knowledge officer and CEO to lead the venture.
Last month, the Eclipse Foundation released Eclipse Zenoh 1.0.0, a protocol that combines communication, storage, and computation capabilities for embedded systems and platforms. The inspiration behind our renowned brand stems from years of tireless labor and proven real-world deployment experience, solidifying the foundation for a groundbreaking new launch.
DDS works effectively, with limits
By 2015, initiatives to develop a robust protocol for interchanging IP addresses in the next-generation web continued to be largely rooted in traditional phone circuit-switching principles. While DDS was designed with a specific purpose in mind, its efficacy was undoubtedly constrained by inherent limitations, as famously acknowledged by Corsaro.
“Our team was also involved in some of the earliest smart-city initiatives, including projects such as those in France and collaborations with Schneider and Cisco in Barcelona,” he explained. One of the key battles we faced was integrating multiple protocols for data transfer, requiring us to combine two to three distinct technologies ranging from microcontrollers to knowledge middleware. DDS wouldn’t scale to meet the demands of a microcontroller, nor was its underlying wire protocol optimized for low-bandwidth connectivity.
“The issue arose when DDS was utilized outside of its original design parameters,” Since the design of DDS, we had envisioned a scenario where the network would function as a self-contained, wirelessly connected community with minimal packet loss. In a system that has been carefully designed and dimensioned.
“So, we acquired this naval battle management system from DDS, which has a comprehensive architecture,” he said. “There may be a general consensus that the system is commonly experiencing 50% CPU usage, leaving a significant portion of the community with empty resources.” The entire setup is designed to accommodate multicast functionality and ensure reliable data transmission, preventing packet loss. Techniques are remarkably effective and well-balanced in their symmetry. DDS indeed excels in its native domain, but its value diminishes when applied outside of that specific sphere.

Zenoh enables seamless handling of data in both static and dynamic environments.
Corsaro reported that he was grappling with resolving two key matters. The primary goal was to develop a protocol that would effectively work with low-power embedded systems and constrained resources.
“Corsaro remembered that reconciling opposing concepts allowed us to abstractly cope with information while moving or relaxing – a notion that raises questions.” To facilitate decentralized data storage for fog computing initiatives in Barcelona, he identified a need for protocols that could efficiently retrieve and aggregate information dispersed across various nodes.
“By eliminating the topological constraint, this technology enables computations to operate seamlessly across arbitrarily complex mesh structures at massive web scales,” While technology allows for seamless data transfer, this vague passage remains unclear. Here’s a revised version:
“As we move away from physical storage, the debate between cloud computing and on-premise infrastructure becomes less relevant. With advanced analytics and data processing capabilities, information naturally gravitates towards its most efficient route.”
From telecom to ROS 2
DDS researchers, backed by telecom firm funding, embarked on Zenoh, leveraging this support to test and verify its potential in smart-city telemetry applications across various networks, according to Corsaro.
“It was serendipity that led to the technology’s application in robotics, a consequence of our primary focus being telecommunications,” he noted. As we showcased its potential integration with ROS, the project’s popularity suddenly surged.
As ZettaScale separated, TG Tech Auto recognized an opportunity to integrate its protocols within the organization and formed a strategic partnership, acquiring a stake in the process.
“We’re witnessing a significant convergence between the robotics and automotive industries, with Zenoh being selected by General Motors’ uProtocol initiative,” Corsaro stated. The synergy between architectural design and technical expertise. In reality, there are already vehicles in Asia that are currently operational using ROS 2.
As autonomous systems converge, ROS 2 adopts a code-centric approach, in contrast to the AUTOSAR consortium’s focus on standardized interfaces and seamless communication protocols. Notwithstanding, ROS 2 aims to meet automotive industry certification standards, as acknowledged by Corsaro.
Companies akin to theirs are actively working to bridge the gap between these platforms. Intrinsic leverages Zenoh in conjunction with ROS 2 Jazzy Jalisco for seamless integration.
“Corsaro notes that the current era is particularly captivating.” Consider whether a uniform protocol could be applied across all robotic platforms and autonomous driving systems. While some may view robotics as a technology primarily adopted by early adopters,
At the recent ROSCon event held in Kyoto, Japan, ZettaScale and Zenoh unveiled their latest Model 1.0.2.

ZettaScale continues automotive work
The Zenoh platform seamlessly integrates with prominent automotive companies and forward-thinking smart city organizations.
Eclipse Zenoh 1.0.0 boasts a suite of innovative features, including shared reminiscence capabilities, zero-copy support, enhanced end-to-end security, high-performance edge management, and specialized extensions for robotics and automotive protocols.
“Corsaro emphasized that the company has successfully integrated real-time video from self-driving cars into its recognition system, effectively incorporating this data into its processing loop.” While you don’t need to engage with the community for sending large files like lidar images, level clouds, or massive photographs, surprisingly few developers have utilized the zero-copy API available within ROS.
ZettaScale collaborates intensively with partners in Japan and Europe, while maintaining a strong support presence within the United States.
