Ex db IIC T6 Gb explosion-proof wheeled robot with IP66, 4WD, SLAM navigation, ≤±3 cm positioning, multi-gas monitoring, and 1080P camera for hazardous area autonomous inspection.
The Explosion-Proof Wheeled Robot achieves Ex db IIC T6 Gb explosion-proof rating and IP66 protection. Employing four-wheel all-wheel-drive with differential steering and SLAM laser navigation and positioning, it provides unmanned autonomous inspection, environmental perception and data collection, and intelligent obstacle avoidance for safe, intelligent inspection in flammable and explosive environments.
In oil and gas extraction, pipeline transport, petrochemical processing, and chemical manufacturing, routine inspection is essential for safety and regulatory compliance — yet the environments where inspection is most needed are precisely those where human entry is most dangerous. The Explosion-Proof Wheeled Robot is engineered to perform this critical inspection function autonomously, with the highest explosion protection rating and rugged environmental protection needed for Zone 1 hazardous area deployment.
The robot's mobility platform employs four-wheel all-wheel-drive with differential steering, enabling zero-radius turning for maneuvering in confined spaces between process equipment. The platform achieves a travel speed of 0–1.4 m/s, a climbing capability of ≥25°, and an obstacle-crossing ability of ≥120 mm height and ≤100 mm width. The operating endurance is up to 5 hours per charge, providing sufficient runtime for comprehensive facility inspection rounds. The SLAM laser navigation and positioning system achieves repeat positioning accuracy of ≤±3 cm, with a 360° lidar detection radius of 0–10 m. The industrial-grade remote controller response latency is ≤200 ms, and the emergency-stop response time is within 0.5 seconds.
Autonomous inspection is based on the SLAM algorithm, supporting both pre-defined inspection routes and dynamic path planning. The robot supports ≥100 inspection points per route, and in the event of network interruption, switches to a local storage mode that continues inspection and preserves data for synchronization when connectivity is restored. Environmental gas monitoring is performed by a multi-gas sensor array detecting O₂, combustible gases, CO, and H₂S with ±5% FS accuracy. Video monitoring uses a 1080P explosion-proof camera with infrared night vision range ≥20 m and 64 GB local storage. Optional capabilities include methane laser telemetry, flame detection, and meteorological environment data collection.
The robot's communication system supports 4G/5G + Wi-Fi dual-mode networking with ≥10 Mbps transmission rate, enabling real-time video and sensor data streaming to the control center. Bidirectional voice and voice broadcast capabilities enable the robot to serve as a mobile communication node during emergency response. Intelligent charging functionality enables the robot to autonomously return to its charging dock with a docking error of ≤±2 cm. Safety is ensured by an 8-group ultrasonic omnidirectional collision-avoidance system, a mechanical buffer anti-collision strip, three-level emergency-stop protection, and intelligent obstacle avoidance algorithms.
