On the ground, small unmanned ground vehicles (UGVs) can enable rescuers to find and interact with trapeed victims in void that are too small or too dangerous for human or canine entry. Large UGVs can accomphish tasks such as removing large rubble faster than humans. In the air, unmanned aerial vehicles (UAVs) robots extend the senses of the responder by providing a bird’s eye view of the situation. In the water, unmanned underwater vehicles (UUVs) and surface vehicles (USUSs) robots can similarly extend and enhance the rescuers sensens.
Rescue Robots can be broadly categorized into types based on modality and size, though other taxonomies that mix modality, size and task have been proposed. There are four modalities of robots: ground, aerial, underwater and water surface. The modality impacts on the basic design and capabilities of the robot. Within each modality. rescue robots can be further describe as a one of three sizes: man-packable, man-portable, and maxi. The size of the robot impacts both on the tasks for which it is suited and how soon after a disaster it might be used. In order to be man-packable, the entire robot system, including the control unit, batteries, and tools, must fi into one or two backpacks. Man-packable robots are more likely to be used immediately after a disaster since they can be carried by responders over debris and up and down ladders into the core of the disaster, while larger size is man-portable; these are robots than can be carried a short distances by two people or on a small all-terrain vehicle. Man-portable robots can be used as accessibility within the hot zone improves or outside the hot zone for logistics support. Maxi-sixed robots require trailers or other special transportation logilitics. This inhibitgs their insertion into the hot zone, unless the are being used on the exterior of the rubble.
