The Topsky Tianlong Conquest 4x4EV1 is a heavy unmanned ground vehicle (UGV) positioned as a rescue support platform rather than a single-purpose suppression robot. Built around a safety-first design philosophy, it concentrates on three core roles: reconnaissance support for remote scene approach and assessment, transportation of rescue equipment and materials including hoses and tools, and logistics assistance such as dragging charged fire hoses into position. With a published load capacity of at least 450 kg and a traction force of at least 4,500 N, it can move equipment caches, stage tools nearer the hazard zone, and maintain hose advancement without requiring firefighters to haul heavy lines forward by hand.

Engineered for demanding emergency terrain, the 4x4EV1 emphasizes all-weather positioning and navigation and is rated for climbing, wading, and crossing typical industrial barriers, with published figures of 35 degrees (70%) climbing ability, at least 300 mm obstacle crossing, and at least 500 mm wading depth. A maximum linear speed of at least 1.8 m/s supports rapid repositioning across large sites such as warehouses, refineries, plants, ports, and disaster areas, where time to contact can influence containment and rescue outcomes. Its multi-functional profile also suits debris-field reconnaissance, transport of demolition tools and support materials, and short-range supply runs in disaster logistics corridors.
