28.2.1. Based on Mobility

• Wheeled Robots: Suitable for even, semi-damaged terrains

Wheeled robots are designed to move smoothly across flat, hard surfaces, making them ideal for environments that are somewhat intact. They can navigate roads or paths that have only minor obstacles, providing efficient mobility for search and rescue operations.

Think of wheeled robots like a shopping cart in a supermarket. It moves easily on the flat ground, helping you carry items. Similarly, wheeled robots move efficiently in areas that are not severely damaged.

• Tracked Robots: Enhanced mobility on uneven, rough terrain

Tracked robots utilize continuous tracks, similar to those on a bulldozer, allowing them to traverse bumpy or rugged surfaces. This makes them effective in disaster zones where debris and uneven ground limit movement for other types of robots.

Imagine a tank moving over a battlefield; the tracks allow it to cross obstacles and navigate difficult conditions. Tracked robots operate on the same principle, making them suited for debris-laden environments following disasters.

• Legged Robots: Inspired by animal locomotion; ideal for navigating debris

Legged robots mimic the movement of animals to walk over various types of terrain, which is particularly helpful in navigating through debris fields. They can actually step over obstacles and adapt to different surfaces, providing distinctive advantages in chaotic environments.

Consider how a dog moves through a park, easily walking over sticks or uneven ground without much issue. Similarly, legged robots can navigate complex spaces within collapsed buildings, helping to search for victims.

• Aerial Robots (Drones/UAVs): Used for locating victims from air, thermal imaging

Aerial robots, such as drones, are invaluable in search and rescue operations due to their ability to survey large areas from the air. They can quickly locate victims using thermal imaging technologies, identifying body heat even through rubble or dense vegetation.

Imagine a bird soaring high above a forest, spotting small movements below. Aerial drones do just this in rescue missions—they can quickly cover extensive areas to find those in need of help more efficiently than ground teams.

• Underwater Robots (ROVs/AUVs): Deployed in flood or submerged environments

Underwater robots, which include remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs), are specifically designed for aquatic environments. They assist in locating victims and conducting operations in areas that are flooded or submerged, where human divers might be at risk.

Think of these underwater robots like submarines, which can go deep into the ocean to explore. In a rescue context, if a building is submerged, these robots can help by exploring underwater to find survivors trapped inside.

• Hybrid Robots: Combines features of multiple mobility systems

Hybrid robots integrate multiple mobility systems, such as wheeled, tracked, and legged designs, allowing them to transition between different environments seamlessly. This versatility enables them to tackle a variety of challenges during search and rescue missions.

Think of a Swiss Army knife—the tool that has multiple functions in one compact design. Similarly, hybrid robots can adapt their movement strategies to handle various obstacles, making them highly effective in unpredictable disaster situations.
