Now we will talk about the impact of robots in the environmental field:
As we have known since the invention of robotics, the work has been divided between man and machine, But because of the growing sophistication of robots technically and personally, they knew how to perform jobs faster and better than humans, So they were given jobs that humans could not do , Especially in :
1. the examination of hazardous environments
Robots become more important for scanning and searching dangerous environments. These robots are able to enter an active volcano to gather information or a burning building to search for victims. Robots such as the " Scout Trooper robot" are used by law enforcement agencies and fire departments to help find information about people stranded in a building and even have the ability to detect bombs or explosives in the area. These robots without a commander also protect lives because they protect humans from having to enter the dangerous environment without knowing what awaits them.

Robotics for Land-Mine Detection:
Approximately 60 to 100 million landmines are deployed in more than 60 countries
After a century of conflict. The presence of these mines has serious consequences for the civilian population, resulting in millions of acres of un trustable land. Thousands of innocent people are being maimed or killed each year in landmine incidents. At present, most landmine detection is done manually, using metal sensors and other types of sensors (see figure 2.1). Often, the sensor indicates the presence of the metal when it is not present, leading to false alarms. Worse still, with the deployment of mines with little or no mineral content, the use of the classical metal detector is limited. For every 5",000 mines removed, mines are killed or maimed. More sophisticated techniques are needed, and robotics techniques offer a unique opportunity to create a secure solution. Independent robots with appropriate sensors can systematically search in a given area and identify all possible landmine areas, resulting in significantly higher detection rates and reduced casualties (see figure 2.2). The newer sensors, such as quadrilateral and explosive odor detectors, called "sniffers", should be available within a few years. Quadrilateral resonance, a technique of radio-frequency imaging similar to magnetic resonance imaging but without the large external magnet, is a promising technical alternative. Air electronic inhalers can detect the presence or presence of mines quickly.

2. In Underwater Discovery:
Underwater robots can dive longer and deeper than anyone and provide a closer look at marine life. These stunning machines are equipped with sensors, high-definition cameras, wheels and other technology to assist scientists when they explore anchors, ocean bottoms, dams, ship liners and other surfaces. The most known underground robots used today are remotely operated vehicles controlled by individuals sitting at the command center. These vehicles are connected by ship cables, the best way to collect information and images of underwater life.
