The increasing role of robots in national security.
When most people think of national security and the global war on terrorism Terrorist acts and the threat of Terrorism have occupied the various law enforcement agencies in the U.S. government for many years. The Anti-Terrorism and Effective Death Penalty Act of 1996, as amended by the usa patriot act , they often focus on the activities taking place in Afghanistan and Iraq. However, the war on terrorism is genuinely global and is being fought in many places beyond U.S. Central Command's area of responsibility in the Middle East and the Horn of Africa Horn of Africa, peninsula, NE Africa, opposite the S Arabia Peninsula. Also known as the Somali Peninsula, it encompasses Somalia and E Ethiopia and is the easternmost extension of the continent, separating the Gulf of Aden from the Indian Ocean. . From Asia to South America South America, fourth largest continent (1991 est. pop. 299,150,000), c.6,880,000 sq mi (17,819,000 sq km), the southern of the two continents of the Western Hemisphere. , servicemembers are pursuing multiple strategies to prevent the planning and execution of terrorist attacks. These strategies involve working with our partner nations around the world to conduct humanitarian missions, secure their borders, exchange intelligence, and help train their militaries. A major challenge for the Department of Defense is that there are various issues in many parts of the world and only so many personnel to go around.
So how can we continue to effectively prosecute numerous missions in so many different locations? We must give the servicemembers better tools--such as robots.
Already in Afghanistan and Iraq, servicemembers have embraced a new world in which man and robot work side by side. In 2001, there were only 120 tele-operated robots in theater, conducting cave reconnaissance. Today, ground robots have increased their presence in theater to nearly 6,000, and more are on the way. The robots still conduct reconnaissance, but they also assist with vehicle inspection, roadside inspection, and defeat of improvised explosive devices Noun 1. improvised explosive device - an explosive device that is improvised

Operators have become so adept at the robots' use and so attached to them that they name them and think of them as members of the team.
Potential New Military Uses for Robots
We are only at the beginning of what is likely to be a long and growing relationship between robots and DoD personnel. The technology of robotics is growing by leaps and bounds, thanks largely to funding and oversight by DoD's acquisition and technology organizations. In laboratories today, robots are being developed to carry equipment for dismounted soldiers traveling on foot in extreme terrain. Robots are being designed to rescue the wounded, stand sentry duty, detect and neutralize mines, clear ranges of unexploded ordnance "UXO" redirects here. For the cancelled video game, see .
Unexploded ordnance (or UXOs/UXBs, sometimes acronymized as UO) are explosive weapons (bombs, bullets, shells, grenades, land mines, naval mines, etc. , search for dirty bombs, and more. What is so important is not that robots will replace personnel, but that they will allow the same number of personnel to do more, over larger areas of responsibility--exactly what is needed for increased national security.
In U.S. Southern Command's area of responsibility in Central and South America and the Caribbean, one of the most significant threats to national security is the drug trade and narco-terrorism. Drug revenues finance and equip terrorists and insurgents Insurgents, in U.S. history, the Republican Senators and Representatives who in 1909–10 rose against the Republican standpatters controlling Congress, to oppose the Payne-Aldrich tariff and the dictatorial power of House speaker Joseph G.

Vast areas could be covered by the unmanned systems, and personnel would be sent in only after confirmation that interdiction is warranted. This is an idea that capitalizes on the advantages of robotics. Robots can operate for long periods without becoming fatigued and losing their sharp perception--they don't get tired or hungry--and they keep personnel from being detected and harmed by insurgents.
In addition to battling drug trafficking, SOUTHCOM also operates in areas beset by IEDs and anti-personnel mines Anti-personnel mines are a form of mines designed for use against humans as opposed to anti-tank mines, which are designed for use against vehicles.
This type of land mine is normally designed to injure—as opposed to killing—as many enemies as possible in order . SOUTHCOM is working with partner nation Chile to eliminate anti-personnel mines using another ground robot that has the ability to clear unexploded ordnance day and night, three times faster than human beings and at one third less cost, according to according to

U.S. Pacific Command is also challenged by extreme terrain in its area of responsibility in the Asia-Pacific region. PACOM PACOM Pacific Command
PACOM Pan-African Committee (for START, the Global Change System for Research, Analysis and Training) is exploring the possibility that robots can help carry gear into areas unreachable by ships, aircraft, or land vehicles.

The name is also sometimes applied to the hinny, the offspring of a male horse and female donkey; hinnies are considered inferior to mules. that shows great promise in autonomously traversing difficult terrain that must be traveled on foot. This would be of great benefit to today's servicemembers, who are often asked to carry over 120 pounds of gear--an extremely fatiguing activity in high temperature and humidity conditions.

We Have the Technology. Now How Do We Integrate It?
While DoD is pursuing a wide variety of robotic applications, successfully integrating them into the armed forces requires more than just success in the laboratory. It also requires an understanding of how to actually employ the technology in real-world conditions, in which one may be called upon to perform quite different missions from usual. Determining how to integrate robots is not easy, partly because there are relatively few robots currently in use within the armed forces, and also because there are just not many people in DoD (or the world, for that matter) who have much experience working with them.
A current effort associated with using robotic vehicles in convoys provides an example of what must be considered and resolved before integrating and deploying robots in the field. The military uses convoys all over the world to move supplies and maneuver units from one point to another. Current robotic technology is not mature enough for supply trucks to follow one another in a convoy over a protracted pro·tract

2. route with no human drivers at all. However, the technology has developed to the point where certain vehicle-driving tasks can be performed by the trucks themselves. So now technical experts, military planners, and end-users must work together to consider when, how, and to what extent convoy missions might be conducted using robotic technology.
The answers are not immediately obvious, and many more questions have arisen as various integration scenarios are analyzed. For example:
* If an autonomous truck can drive itself by following a truck in front with a human driver, how many such vehicles should make up a typical convoy--three, a dozen, 40, or some number in between?
* Can the autonomous "follower" vehicle react to unexpected obstacles in the road, such as a deer suddenly running between it and the lead truck?
* How closely should an autonomous vehicle A passenger vehicle that drives by itself. Also known as the "driverless car," it automatically steers the vehicle by sensing the painted lines in the road or a magnetic monorail embedded in the road. In the late 1990s, prototype systems were built in Italy and the U.S. See automotive systems. follow the lead vehicle?
* How far apart can the vehicles be while still maintaining the integrity of the convoy?
* How many people are still needed to adequately move the convoy (drive the lead vehicles, provide security, load and unload the trucks, etc.)?
* What ratio and position of trucks with drivers, relative to those without drivers, will provide the most effective convoy configuration? Should every other truck be autonomous? Perhaps only every fourth truck would require a driver?

The existing methods for conducting a mission with manned equipment cannot simply be continued with a robot replacing a person. New operational concepts need to be created based on an understanding of both the capabilities and limitations of the robot.
Learning to Work Together
This challenge is compounded when considering robots in different domains working together to conduct a single mission. Much of how the armed forces conduct their missions is predicated on two considerations. First, the domain of air, land, or sea determines how tasks are accomplished, since, for example, conducting reconnaissance from the air is very different from performing that same task on the ground in a jungle environment. The second consideration is how to allocate tasks between people and unmanned equipment when working across the domains. The way DoD currently conducts joint operations A general term to describe military actions conducted by joint forces or by Service forces in relationships (e.g., support, coordinating authority) which, of themselves, do not create joint forces. will change dramatically when robots are introduced to the inventory. Many tasks for which the Army now relies on Air Force pilots will be conducted by unmanned aerial vehicles, so interactions between the Army and Air Force will likely change dramatically.
The next logical step in the employment of robotic technology is the concept of robots in the air, on the ground, under water, and on the ocean surface, all collaborating to conduct a mission. It's easy to envision these autonomous systems A network that is administered by a single set of management rules that are controlled by one person, group or organization. Autonomous systems often use only one routing protocol, although multiple protocols can be used. The core of the Internet is made up of many autonomous systems. working together, but the actual techniques needed to manage interactions between the systems are still very much in their infancy. If unmanned ground, surface, and aerial vehicles are working together to conduct a river-based reconnaissance mission, how do the ground and the surface vehicles react if the aerial vehicle loses communications because vegetation is thicker than originally believed? Do the remaining vehicles continue the mission, or do they stop in place to await restoration of communications? When people are taken out of the mission equation, the military techniques and procedures that robots follow will not always be the same as personnel have previously used to conduct the same type of mission. New operating procedures and tactics will have to be developed.
Fortunately, experimentation with new technology is nothing new for DoD. A variety of opportunities and tools are available to determine how best to answer the types of questions posed above. In addition to creating robots, DoD is creating virtual environments in which actual software algorithms that control the robots and provide the ability to conduct tactical behaviors, such as reconnaissance can be tested before spending the funds to build a complete robot. These virtual environments help refine the software algorithms and provide a greater number of personnel experience with robotic behavior, so operational issues can be more fully explored.
As powerful as these virtual environments are for exploring concepts and testing the effectiveness of software-controlled behaviors, sometimes there is no substitute for live experimentation. Potential user experimentation with robots is uncovering operational insights that can demonstrate a need for technology that was not originally considered. Users invariably in·var·i·a·ble

in·vari·a·bil take into account operational aspects that don't occur to the scientists and engineers developing the robots, so an opportunity to experiment with the technology while it is still maturing leads to fielding more effective and suitable robots.
When looking at the robotic convoy concept, for example, users indicated a strong preference for the robots to be able to operate at night. When human drivers conduct night convoy operations, they have to be able to see. Robots have a variety of means to "see" in the dark that can potentially provide the convoy with greater capability for nighttime operations than would normally be possible with human drivers. The potential for traveling with shorter distances between vehicles to enable greater security, the ability to travel without giving off much light to avoid revealing the presence of the convoy in the dark, and the ability to travel at higher speeds yet with greater safety are all benefits the robotic convoy technology can potentially deliver. Live experimentation will help users decide which benefits are most helpful in enabling them to conduct their convoy missions with greater effectiveness and lower risk than they do today.

The list of potential jobs for robots in national security varies widely, but the increasing role of robots gives soldiers, Marines, sailors, and airmen the ability to conduct their missions with much less risk. Even though there are thousands of robots already in the inventory, DoD has barely scratched the surface of what is possible. The expectation over the next 10 years is that DoD will integrate robotic technology into many types of missions, and robots will take their place alongside military personnel in keeping the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America.
