The Trailer Drone is a future-oriented transportation system that maximizes the efficiency of long-distance logistics and transportation by mounting a hydrogen fuel cell and fully autonomous driving technology. It is possible to travel more than 1,000 km on a single charge. Thanks to fast fuel charging, one of the characteristics of FCEVs, more efficient long-distance driving than existing large commercial vehicles is possible. The unmanned autonomous driving technology of trailer drones is a key technology that will bring innovation to the logistics industry. It strengthens logistics competitiveness and dramatically reduces the incidence of accidents with large commercial vehicles that cause great damage. In particular, the 'e-Bogie' constituting the trailer drone can be driven alone, so it can be operated in various fields such as logistics, firefighting, rescue, and construction.
