The Topsky Tianlong Conquest 4x4EV is a heavy-duty unmanned ground vehicle (UGV) built for frontline firefighting and industrial emergency response. Rather than acting as a camera on wheels, it is engineered to take on operational work: entering hazardous areas ahead of crews, transporting critical equipment, and handling the physically demanding task of dragging charged fire hoses. Its four-wheel-drive electric chassis balances stability and maneuverability on roads, paved industrial surfaces, and warehouse floors while retaining the traction needed for uneven terrain and debris-strewn scenes. With a published traction force of at least 4,500 N, the platform can pull two DN80 full water hoses over distances of 80 m or more, easing one of the heaviest burdens in industrial fire suppression.

Designed for reconnaissance and transport in a single platform, the 4x4EV suits industrial sites, tunnels, warehouses, utility corridors, and other locations where heat, smoke, debris, and water runoff make conditions unsafe for responders. An intelligent following system lets the robot trail responders or vehicles while carrying equipment, reducing manual driving workload when visibility is poor or operators are managing several tasks at once. Two-way message communication supports coordination between entry teams and incident command, helping crews maintain suppression progress and standoff distance while keeping personnel out of the most dangerous zones.
