Each year, thousands of human equivalents are killed by natural catastrophes that impact hundreds of millions of people. As a result, there is a strong need to upgrade the rescue system to one that is more advantageous and effective. With the invention and introduction of new technologies, robots have recently shown to be of considerable assistance in this industry. They are able to work in dangerous conditions and squeeze into tiny or awkward locations. They are also never weary. Furthermore, they've shown time and time again that they're better and quicker than humans at finding survivors in disaster zones, which not only saves lives but also enables the impacted community to start the path to recovery more quickly. The roles of airborne, terrestrial, and marine robotic systems in search and rescue (SAR) and salvage operations are being revolutionized by the quick advancements in technology. Robots and drones are used to communicate, gather data, carry supplies, and direct rescues in environments judged too dangerous for humans. Rescue robots are made to do a certain task that has been allocated to them, one that may be too dangerous for humans to perform. Another difficulty that these robots can handle is rescuing individuals from hazardous situations. The individuals from the afflicted areas are found by rescue robots. A robot that has been built specifically with human rescue in mind is a rescue robot. Mine accidents, urban catastrophes, hostage situations, and explosions are typical uses for rescue robots. Rescue robots may help these missions by reducing the number of persons needed, reducing tiredness, and providing access to places that wouldn't otherwise be accessible. With features including finding, mapping, clearing or shoring up debris, delivering supplies, providing medical care, and evacuating victims, rescue robots are currently being developed.
