The 'GHOST' Drone concept has been designed as a solution for public transit maintenance that would eliminate the need for staff to spend extended periods scrubbing floors and trains. The flying unit is outfitted with high-power UV lights that bathe the entire area around it in sanitizing illumination, which will work to clean both the surfaces as well as the air. This can be done in a rapid process and doesn't require anything to be placed on the floor to further enhance the complete cleaning capabilities of the unit.
The 'GHOST' Drone concept is the design work of Off Garage Studio including Yungi Min, Sunghyun Kwon, Ikhyeon Kim and Byeongjae Ha. The unit speaks to an increased need for autonomous infrastructure equipment as urban locations grow in size and population.
