Air Duct Inspection Robot

The ZHROB-MB is a fully autonomous, tether-free robot designed for confined space inspection. Its key specifications are as follows: 1. Key Inspection Capabilities • Imaging Function: Supports 2K video recording and still photography. • Range & Stability: Equipped with a 3-axis stabilised gimbal camera, supporting a rotation range of 115° × 320° × 60°. • Zoom Capability: The gimbal camera supports 30x hybrid zoom and 10x optical zoom. It features a 1/2.7-inch high-sensitivity CMOS sensor for superior low-light performance. • Duct Adaptability: Suitable for air ducts and pipes with a height greater than 400 mm and a width greater than 400 mm. 2. Intelligence & Autonomous Operations • Autonomous Localisation & Exploration in Confined Spaces: o Utilises a multi-sensor fusion scheme incorporating an IMU, LiDAR and binocular stereo depth cameras. o Capable of millimetre-level mapping, autonomous obstacle avoidance and autonomous exploration navigation, even in confined, dark and low-texture environments. • Anomaly Recognition Function: o Powered by a Vision-Language Model (VLM) and AI reinforcement learning algorithms. o Autonomously and precisely identifies structural anomalies (e.g., breakage, water seepage, rust) and foreign objects (e.g., construction debris, rebar, rubble). o Records 2K high-definition video via the gimbal camera. o Automatic tagging and localisation: Automatically sends alert notifications, identifies the type of anomaly, and provides maintenance recommendations and solutions. 3. Basic Performance • Endurance: Built-in 24V 25Ah ternary lithium battery, providing > 4 hours of continuous operation. • Wireless Transmission: o Features 2.4G + 5.8G dual-band communication modules. o Configured with a professional remote control console. o Supports wireless video transmission with a remote control range of > 5 km and data latency < 170 ms. • Chassis Architecture: o Adopts a four-wheel differential drive architecture. o Maximum torque per wheel reaches 2 N·m, providing ample power. o Obstacle Crossing & Climbing: Supports a 35° gradeability (climbing angle) and can cross obstacles up to 40 mm in height, ensuring excellent passability.
