Excavators are indispensable important machinery for flood and earthquake relief. In addition to excavators, drones now also play an indispensable role.
Drones play the role of ‘thousand-mile eyes’ in rescue work. These aircraft can fully utilize advantages such as small size, light weight, and low-altitude flight to overcome difficulties that large aircraft find difficult to cope with, such as terrain, climate, and air currents. They can timely obtain information on road conditions in disaster areas, the distribution of destroyed buildings after the disaster, conduct life sign searches on dangerous buildings after earthquakes through hovering, use onboard cameras to capture and transmit high-resolution images and photos in real-time, and provide decision-making information for targeted scheduling and deployment for rescue teams.
With long maximum flight times and strong wind resistance, drones are greatly needed in areas where many excavators and humans cannot enter.
In summary, drones play the following roles in disaster relief:
- Remote sensing mapping, hazard investigation: can quickly draw accurate topographic maps by flying deep into dangerous disaster areas, capture and transmit real-time images of disaster areas at ultra-low altitudes.
- Route planning, communication relay: use robots to guide and select the most accessible routes for rescue operations.
Transport and search and rescue: in dangerous environments, robots can also carry rescue supplies, and tracked load-bearing ‘small cars’ can enter ruins and move and detect inside collapsed buildings.
With flying drones in the air and load-bearing unmanned armored vehicles on the ground, it can be said that these flexible small devices are playing an increasingly important role in serving humanity!
