TRON 2 in Action: Autonomous Utility Tunnel Inspection TRON 2 demonstrates a closed-loop autonomous inspection workflow in a real-world municipal utility tunnel—from mapping and navigation to multi-level inspection, anomaly detection and response, and autonomous docking and charging. Equipped with the Autonomous Mobile Manipulation Kit, TRON 2 navigates complex spatial structures, adjusts its posture to inspect points at varying heights, and performs light-duty manipulation to assist with alarm response. When battery levels run low, it autonomously returns to its charging dock, supporting extended, unattended inspection operations. This real-world deployment highlights the potential of embodied AI in municipal infrastructure, industrial inspection, and other complex operational environments.
