Today, I bring you the first of three sections for my special post on robotics. This first section will discuss how robots are making a difference in the air.
What is a UAV
Today in the news, we hear comments about "UAVs" and "Predators" and "drones" conducting strikes in Pakistan. Now, what are these? Believe it or not, UAVs are commonly mistaken to be missiles, or some government top secret project.
UAV is the acronym for 'unmanned aerial vehicle.' It is a very broad area of robotics because it literally consists of all robotic airplanes that can fly without a human on board. Believe it or not, the UAVs have been around since the 1950s, and a couple were used during the Vietnam War. They were very inefficient, and their plans for development were scrapped because few politicians believed that they would be achievable. However, they were wrong, because now the UAV has been widely used during the War On Terror.
UAVs can be used for a variety of functions in the military. They can be used for surveillance, transportation, unit coordination, and combat. The "Predators" and "Reapers" that are seen in the news being used in Afghanistan in Iraq tend to carry out surveillance and combat roles. The video below shows a Predator UAV carrying out both roles (for those eager for action, the combat is at the very end).
"Light" UAVs like the Predator and Reaper will become very popular in the future with the US military. This is because of several reasons. First, they are very efficient intelligence gatherers. They are mounted with infrared, and near infrared cameras that can zoom and detect almost anything. This can range from the license plate of a car, to a hidden weapon in an insurgent during a VIP visit. UAVs have the ability to fly high, and far away from their targets. In fact, some have flown at 65,000 feet. With the ability to fly so far away and get so much detailed information, this reason alone is almost enough to justify the development for UAVs. Today's current US Border Patrol uses UAVs for intelligence.
The second reason why Light UAVs will become popular is because of their ability to operate in a 'tactical strike' role. Light UAVs like the Predator can be armed with two Stinger air-to-air aircraft missiles, and four hellfire air-to-ground missiles. This gives the Predator the ability to strike light air targets (helicopters and slow aircraft) and almost any enemy ground target. The hellfire missile could easily wipe out several soldiers, and could even penetrate the armor of a tank. When you combine the surveillance and tactical strike capabilities, you get a UAV that can make quick, accurate, successful attacks.
The third reason why Light UAVs will become popular is because of how cost efficient they are. Currently, the US has a wide range of fighters. Older fighters like the F-15 Eagle cost approximately $30 million USD, while more advanced fighters cost $139 million USD. Keep in mind, you have to add in the $1.1 million USD cost for training the pilot.
Light UAVs like the MQ-1 Predator are much cheaper. One UAV Predator system costs $30 million USD. This includes four Predators, their ground control stations, and their own satellite link. However, you could add a limited amount of addition Predators to that system for around $4.9 million USD. Also, keep in mind that it costs much less and takes less time to train a UAV pilot. So, think of what's easier to lose in a mission. A F-22 Raptor, or a MQ-1 Predator UAV. It would definitley be the Predator.
So, to sum it up, Light UAVs will become popular because of their surveillance capabilities, their combat capabilities and their cost efficiency. Light UAVs are becoming advanced enough to fill more combat roles, and can stand in as a more cost efficient solution.
UAVs in the Future
Brace yourself, here comes another acronym: UCAV. UCAV stands for 'unmanned combat aerial vehicle.' These are the future of UAVs. Now you may be thinking, "I thought UAVs were combat capable." Yes, but UCAVs will blow you away.

UCAVs are combat oriented aircraft. Unlike Light UAVs which were built to have basic aircraft capabilities, UCAVs are being designed to have advanced capabilities. They are also being designed to have full autonomous ability.
UCAVs are still in early development, so not much is known about them. However, one particular UCAV, the Boeing X-45 has displayed some impressive feats of what UCAVs will be able to do. In wargames, they've been able to take out targets, autonomously fly and achieve missions, autonomously react to unknown and incoming missiles; all while flying at intense speeds at high altitudes.
Being able to fly at intense speeds and take out targets is a great capability, but doing it autonomously (without human control) is another thing. One pilot was even able to control two X-45s at once because they could operate independently. If these robots are able to accomplish tasks without human guidance, then they are definitley appear in the future. This is because it will allow armies to expand their size and striking capacity greatly, without having to increase the amount of human lives being sent into battle. Also, UCAVs may be able to defeat human controlled planes because they won't be limited by g-forces.
UCAVs are so interesting because they seem to be so science fiction. It's hard to believe that they can really function like this, and harder to think that they will likely be in service by 2015, but it's true. This video below shows the X-45 taking off, flying, and attacking a target autonomously. The only human interaction it encounters is when it receives its objectives.
Network Centric Warfare: The Combination of Systems
Now, this last subtopic isn't about a specific robot, but about a system called "network centric warfare."
Network Centric Warfare (NCW) is a system in which there are different forces that use information technology to share their situation. The US Air Force characterizes NCW "by the ability of geographically dispersed forces to attain a high level of shared battlespace awareness that is exploited to achieve strategic, operational, and tactical objectives in accordance with the commander’s intent. This linking of people, platforms, weapons, sensors, and decision aids into a single network creates a whole that is clearly greater than the sum of its parts." If neither of these make sense, check out the Northdrop Gruman advertisement.
NCWs can be discussed entirely as their own topic, but they can play a large role in the future of robotics in warfare. In the future, when UCAVs are created, they could create a massive, effective fighting force. Hundreds of UCAVs could be launched, and remember they don't require human pilots) with the objective to strike a target. These UCAVs would be 'linked' together so that they would constantly engage data with each other. This data that is exchanged enhances their situational awareness as a whole, which allows them to act, and react differently, which increases their effectiveness.

In George Friedmen's The Next 100 Years, he predicts that a large role of future warfare will evolve around NCW supersonic UCAVs. I support his view. Autonomous UCAVs are great, but creating a NCW for them to operate, will allow them to operate on their own. They will constantly be processing the information, and the more information they receive, the more actions they will make.
The idea of NCW and UCAVs fascinates me and is one of my favorite subjects.
