Disaster strikes, and the world watches as buildings crumble. But it’s not just the damage to structures that’s devastating – it’s the people who go missing. Some are crushed by debris, while others are trapped, waiting for help. That’s where technology comes in.
When every minute counts, the right tools can be a lifeline. Take LiDAR, for instance. This tech uses laser light to create 3D maps, helping rescuers navigate rubble and pinpoint survivors. And it’s not just limited to ground teams – LiDAR can be mounted on drones or vehicles to scan hard-to-reach areas like forests, mountains, or collapsed buildings.
Then there’s FINDER, a portable radar device developed by NASA. This gadget detects the vital signs of people trapped under debris, sending out microwaves to scan for heartbeats and breathing. It’s a game-changer in the aftermath of a disaster.
Drones are another crucial tool in the rescue effort. Equipped with thermal cameras, they can quickly scan large areas, spotting survivors even in low-light conditions or behind obstacles. These cameras work by detecting the infrared radiation emitted by objects, allowing them to “see” people or animals in the dark.
But what about when the situation calls for something more agile? That’s where Iron Dog comes in – a robot that combines LiDAR, thermal cameras, AI, and more to track down survivors in the rubble. Its slender frame and remote operation capabilities make it the perfect tool for navigating tight spaces.
These technologies are not just useful – they’re essential. They save time, reduce risk, and bring hope to those waiting for rescue. And as we’ve seen time and time again, in the face of disaster, every minute counts.
