1.1.1 General Overview
This platform can be used for nuclear, chemical, and biological (NBC) contamination environment reconnaissance and rescue, NBC material sampling, and decontamination of NBC-contaminated environments. The NBC reconnaissance robot consists of the robot body, gamma radiation detector, nuclide identifier, neutron detector, chemical reconnaissance equipment, solid, liquid, and gas sampling equipment, vehicle-mounted sensors, environmental decontamination equipment, and handheld remote terminals. The robot adopts a tracked chassis, offering high maneuverability, good body rigidity, and strong off-road performance. It supports both wired and wireless control depending on operational needs, and can be equipped with different mission systems to meet unmanned reconnaissance operations in various scenarios.
- (1) Measure the gamma dose rate and nuclide types in the target area; measure the neutron dose equivalent rate in the target area.
- (2) Monitor and alarm for contaminated air in the target area, roughly identify the types of toxic gases; determine the types of solid and liquid toxic substances.
- (3) Capture and transfer radiation sources; suppress and spray decontaminate surface-contaminated nuclear and chemical pollutants.
- (4) Nuclear and chemical reconnaissance payloads can be mounted together or separately on the robot platform to perform tasks.
- (5) The robot platform is equipped with cameras for day and night operations, allowing real-time multi-angle monitoring of operations and the surrounding environment.
- (6) The platform includes movement control, equipment control, and provides real-time transmission, storage, querying, display, processing, and reporting of geographic location information, status parameters, and reconnaissance data.
