The Topsky Tianlong Conquest 40BD is a tracked, explosion-proof firefighting and reconnaissance robot associated with the RXR-MC40BD class of fire-extinguishing and scouting machines. Engineered for incidents involving flammable gas or liquid leaks, toxic smoke, high radiant heat, and potential explosion risk, it pairs a high explosion-proof grade of ExdIIB+H2T6Gb with IP67 sealing. Manufacturer documentation for the closely related RXR-MC40BD specifies whole-machine explosion-proof type Exd[ib]IIBT4Gb and an explosion-proof battery power device rated Ex d IIC T6 Gb, reflecting the strict sealing and electrical-safety demands of scenes containing flammable vapours, combustible gases, and conductive moisture.

Built on a tracked chassis with heat-tolerant, fire-retardant rubber and metal-lined tracks, the 40BD maintains traction over slippery floors, wet pavement, and debris fields typical of tanker bays, refinery corridors, and tunnel approaches. It is configured as a medium-expansion foam and scouting robot with a long-range water cannon for standoff knockdown, cooling, and controlled agent application, while its sensor suite supports up to 8 toxic and harmful gases plus 2 environmental parameters. This lets responders measure conditions remotely before deciding how close to approach and when to transition from remote to human operations. An integrated command terminal and cloud connectivity transmit real-time position, power level, audio, video, and gas-environment readings, with support for 4G/5G links.
