Today, demands for the air and marine transportation is increasing Thus, aviation warning lights are installed on top of high-rises and bridges, while buoys are floating on the sea to help safe flight and sailing. These lights have limited life and must be replaced after some time. However, the work for replacement is dangerous.
Even at this moment, workers are performing this operation with their lives at risk.
Light Changer is a drone for replacing the lights safely. Workers can use the camera loaded on the drone to control it simply and complete their tasks, which means that they don’t have to be exposed to dangerous environments anymore
