Simultaneous localization and mapping (SLAM), a fundamental yet demanding robotics function, is increasingly considered for edge deployment within mobile edge computing (MEC) frameworks. In parallel, integrated sensing and communications (ISAC) enables the use of radio channel information, such as channel state information (CSI), as an additional sensing modality in radio-based SLAM. In this paper, we design and implement a CSI-assisted Edge SLAM testbed integrating a custom unmanned ground vehicle (UGV), a ROS2-based SLAM framework, and a 5G Open Radio Access Network (O-RAN) system. The proposed architecture provides an end-toend, cross-layer view of ROS2 sensor data streaming over 5G, explicitly enabling CSI exposure and integration into the SLAM pipeline. We analyze ROS2–DDS communication, RTPS packetization, and 5G user-plane transport, and discuss mechanisms for CSI extraction and delivery via O-RAN components. The platform enables realistic experimentation with communicationaware SLAM and reveals key challenges related to latency, data streaming, synchronization, and cross-system integration, providing insights for future 6G-enabled robotic platforms.  \nIndex Terms—5G/6G, SLAM, O-RAN, Channel State Information, Connected Robotics, Testbeds  \nI. INTRODUCTION  \nConnected robotics is one of the primary use cases for ultra-reliable and low-latency communication (URLLC) in 5G networks [1], and it continues to be a key driver in the evolution towards hyper-reliable low-latency communications (HRLLC) in 6G [2] . Recent studies have explored use case requirements, system architectures, and standardization efforts for 6G-enabled robotic systems [3]–[6] . While early work has often focused on tightly controlled environments or teleoperation-centric applications such as remote surgery [7], increasing attention is being directed towards mobile autonomous robots operating in dynamic and unstructured environments. In such settings, robots must continuously perceive, localize, and map their surroundings while meeting stringent latency and reliability constraints, motivating the offloading of compute-intensive perception and decision-making tasks to edge infrastructure over 5G/6G networks [3], [4] .  \nSimultaneous localization and mapping (SLAM) represents a core building block of autonomous mobile robotics, enabling  \nThis research has been supported by the Ministry of Science, Technological Development and Innovation (Contract No. 451-03-34/2026-03/200156) and the Faculty of Technical Sciences, University of Novi Sad through project“Scientific and Artistic Research Work of Researchers in Teaching and Associate Positions at the Faculty of Technical Sciences, University of Novi Sad 2026”(No. 01-3609/1) .  \nrobots to estimate their pose while constructing a map of the environment from onboard sensor data. Modern SLAM pipelines, particularly those relying on high-rate visual or multi-modal sensing, impose significant computational and communication demands that can exceed the capabilities of resource-constrained robotic platforms. This has motivated the concept of Edge SLAM, where sensor data acquired on the robot is streamed over a 5G network to edge servers executing SLAM algorithms within a mobile edge computing (MEC) framework. While this paradigm offers the potential for enhanced performance and reduced onboard complexity, it introduces new challenges related to real-time data streaming, latency constraints,
