Air Duct Cleaning Robot

The ZHROB-MA is a fully autonomous, wireless air duct cleaning robot designed for high performance. Its key specifications are as follows: 1. Core Cleaning Capabilities • Cleaning Method: Utilises a combination of a 600 RPM high-speed roller brush, 10,000 Pa negative pressure suction, and the spraying of a quaternary ammonium salt solution for disinfection. • Cleaning Range: The cleaning roller brush covers a three-dimensional range of 180° × 115° × 360°. • Cleaning Efficiency: Approx. 154 m²/h (10 times the efficiency of traditional manual labour). • Cleaning Coverage: ≥ 90%. • Duct Adaptability: Suitable for air ducts with a height between 400 mm and 1,200 mm and a width greater than 400 mm. 2. Intelligence & Autonomous Operations • Autonomous Localisation & Navigation in Confined Spaces: o Utilises a multi-sensor fusion system integrating an IMU, LiDAR and binocular stereo depth cameras. o Capable of millimetre-level mapping, autonomous obstacle avoidance and navigation even in confined, dark and low-texture environments. • Autonomous Cleaning Planning: o Uses binocular vision to analyse the condition of dirt inside ducts. o Automatically tailors cleaning plans and generates optimal trajectories to maximise efficiency. • Autonomous Perception & Control of Cleaning Arm: o High-Performance Arm: An algorithm-driven 4-DOF (Degrees of Freedom) robotic arm with joint motors providing 120 N·m of torque to handle various loads. o Adaptive Fitting: Utilises compliant force control technology to ensure the arm adaptively conforms to and thoroughly cleans all four walls (top, bottom, left, right) of the duct. o Safety & Precision: Deeply integrates environmental data to precisely identify obstacle contours and positions. It dynamically adjusts the arm’s trajectory in real time to prevent collisions whilst ensuring high-efficiency operation in complex, confined environments. 3. Basic Performance • Battery Life: Built-in 24V 40Ah ternary lithium battery, supporting continuous operation for > 2.5 hours. • Wireless Transmission: o Equipped with 2.4G + 5.8G dual-band communication modules. o Includes a professional remote control terminal supporting wireless video transmission. o Remote Control Range: > 5 km; Data Latency: < 170 ms. • Chassis Architecture: o Features a Mecanum wheel chassis. o Supports lateral movement, diagonal movement and zero-radius (on-the-spot) turning. o Significantly enhances manoeuvrability in large ducts, bends and confined, sealed spaces.
