Military robots of the present and the future

GERALD MIES

FANUC Robotics Deutschland GmBH, 73765 Neuhausen a.d. F., Germany

The military is unquestionably the first user of new technologies and developments, in technique, and is also, very often, the booster for new developments, when it becomes necessary to invent new technologies for military systems. Many basic technologies, which were used in the military for the first time, have become part of the industrial robot today. However, the definition of military robotics and industrial robotics is still very different. The military has specific, robotized equipment, whereas, in industrial terms, the robot is more of an intelligent, flexible, mass production machine. In the future, the use of industrial robots for military applications will become ever more possible. Price and development of the technical abilities of the modern robot will increase the interest of military users. In the following article, the author will indicate that the motivation for the use of robots, within the military and within industry, is the replacement of humans. The reasons for this replacement are, as follows: quality, cost and humanization; however, using a different approach in each field, of course.

I. Introduction and literature overview

Both industrial and military robots share a common history, which began centuries ago. The use of automatic devices was first recognized at the end of the 19 th Century. There are hardly any books detailing the history of military robots in particular, but the topic is mentioned in standard books on robotics, such as the work of ANGELO1 or SICILIANO and KATHIB,2 for instance. In WILLIAMSON,4 too, gives a historical overview on technology – in this case the early years of spacecraft technology. VÁNYA does the same in Reference 10 dealing with the history of unmanned ground vehicles.

A more detailed view on military robotic devices is given by Singer,3 in, “Wired for War”. His book deals with the history, as well as with the various applications within the military context and with the question of how warfare has been and will be influenced by the use of robots. Similarly, LELE6 makes suggestions on how technology can be used in military contexts. Further outlooks on such robotic usages are given by YOUNG,12 LUNDBERG,14 EDWARDS,15 WEISBIN,16 and BUXBAUM.18 Each of them considers robots as essential supporting devices of the future. CHEN’s work in

Reference 13 and GIACHETTI’s in Reference 19 represent a closer look on what robots will be able to do.

Still, there are works that deal with the conflict between machines on the one hand and moral aspects on the other. In Reference 5 WALLACH explains the importance of teaching robots right from wrong. KOVÁCS11 and COOPER17 understand this as one of the major challenges, as well.

Literature can only conclude from recent projects what the future of military robots will look like. It is quite clear that the military has their own understanding of robots, since they do not discuss humanoids, but, instead, devices that support military actions by performing certain tasks automatically. Singer explores momentary research and gives his conclusions on what military robots will be like in the future.

SZABOLCSI7 gave methodology of the derivation of the critical parameters of the human operators manipulating spatial motion of UAVs and in Reference 8 a complex stochastic mathematical model of the disturbances affecting aircraft motion is derived and proposed for further applications. SZABOLCSI and MIES9 give a short brief upon history and future of modern robotics.

II. First military equipment with robot related abilities

During the 19 th and 20 th Centuries, the evolution of robots has proven to be useful in many fields of life. It was only a question of time until the military would use robotic applications for their own purposes. Advances in computer programming enabled engineers to build constructions that could fulfill things, which were not previously possible.

In his chapter on the history of robots, Singer notes that, Thomas A. Edison and Nikola Tesla were the first to think about military applications. Both men worked on the transmission of electricity and experimented with radio-control devices. Tesla was the one who presented his idea of remote-controlled torpedoes to the U.S. military, but he was rejected.3

During World War I, the development of robotic devices continued. An “electric dog”, more or less a converted tricycle, was built to carry supplies. The vehicle was able to follow a light source, which can be seen as a precursor to laser control.

In 1917, a “land torpedo” was patented. The vehicle was supposed to carry one thousand pounds of explosives behind enemy lines. Caterpillar Tractors built a prototype just before the war ended. The first prototypes of missiles, equipped with preset gyroscopes and barometers, were also built around this time. The so-called Kettering bugs could fly a distance of fifty miles before destroying their target. However, these devices did not have any major effect to the fighting.

Germany was the first nation to use remote controlled weapons on a wider scale. On sea, they defended their lines with unmanned boats, carrying explosives. The system included Tesla’s radio control, as an operator steered the ships, via sea planes, which delivered electricity through a cable to the boat. In World War II, Germany again pioneered in the use of robotic devices; their land torpedo, Goliath, is one of the best known. Its size was comparable to a go-kart and was controlled by remote into enemy tanks and bunkers, carrying 132 pounds of explosives.

One of the major and most effective German inventions was the V-2 rocket, a ballistic missile used during World War II. The rocket was not only the first aircraft to reach space, but the flight was automatically controlled by the LEV-3 guidance system. A horizontal and a vertical gyroscope, connected to the steering vanes, were responsible for lateral stabilization and a gyroscopic accelerometer cut off the engine, with the help of an electrolytic integrator. The human operators only had to adjust the azimuth for the rocket and set up the timing for the engine cut-off. Thus, the V2 was able to fly on a certain ballistic curve that reached the target.4

The V-2 rocket and its successors, the intercontinental ballistic missiles (ICBM), completely changed the nature of modern strategic warfare. From now on, missiles had to be programmed and shot and reached the target automatically without further human interaction. When those powerful missiles were equipped with nuclear weapons, both the United States and the Soviet Union were primarily interested in avoiding strategic nuclear warfare.

All of these military devices might have been first attempts that were not terribly effective, but they have certainly been innovations that served as a basis for further developments. Today, missiles of various kinds, for example torpedoes and tele-operated devices, belong to the military, as the soldiers do.

III. Military robots according to the definition of ‘robotics’

Military robots are related to very different applications and differ to those robots that are used for industrial production, in a way that they do not produce things, but have to interact in warfare. The concept, however, is the same; a device has to fulfill some tasks automatically to qualify as a robot. In military terms, technology focuses on the control of missiles and vehicles in order to have unmanned devices that are either tele-operated or that find their way, automatically guided by laser beams or GPS satellites. Today, military robots can be divided into several categories: guided missiles; military spacecraft; unmanned aerial vehicles (UAV); unmanned ground vehicles (UGV); remotely operated vehicles (ROV); and autonomous underwater vehicles (AUV).1

The intercontinental ballistic missiles, mentioned earlier, are only one very large type of rocket with guidance systems. In fact, various combat situations require different types, depending on where the missiles are launched, for what kind of aims they are determined and on how they fly – in a ballistic curve or self-propelled. Combat pilots, for example, fire self-propelled air-to-air missiles at their opponents’ fighter jets, but air-to-surface missiles at hostile targets on the ground. Surface-to-surface missiles can either be self-propelled or ballistic, like the mentioned intercontinental missiles.1

During the first Gulf War, such missiles were described as “smart bombs”. Singer explains that two systems were used; laser-guided missiles and so-called cruise missiles, which find their way by comparing the terrain with digital photographs of it. From this point on, soldiers were able to control such missiles from a safe distance by programming them before the take-off. Due to exact surveillance and precise laser-marks, the precision of the missiles was remarkably good.3

In space, the military is present with satellites, which are basically robotic spacecrafts that orbit around the earth. First installed during the 1960s, the satellites have become crucial instruments for modern warfare and, even for the preservation of a stable, globalized civilization. Such satellites perform a wide range of military purposes, reaching from missile surveillance over navigation to intelligence gathering, which makes them similar to a military scout that gets all the necessary information for further military actions. The military, of course, needs this information in order to plan actions and feed other robots. Surveillance by satellites is necessary work for strategic warfare. These spacecrafts, for example, give early warnings about ballistic attacks, which initiate fast reactions and detect nuclear detonations, which is helpful when it comes to nuclear test ban treaties. They are also able to monitor the weather at tactical or regional level.1

The rise of the Global Positioning System (GPS), during the 1990s, has made satellites even more valuable. Navigating via GPS is the most precise way to find a destination. This technology can now be combined with unmanned vehicles, giving soldiers the opportunity to control their rockets, aircrafts, or ground vehicles from all over the world.

Unmanned vehicles are important instruments in modern warfare. The most widely spread, the so-called drones, are predominantly used for surveillance. These small aircrafts can take pictures of a region without being recognized as large planes. If an enemy shoots the drone down, the loss is relatively small and, more importantly, does not harm any humans. Both drones and unmanned ground vehicles can also be used as weapons. Soldiers can control the bomb and gun carrying devices via satellite and do fear human casualties on their own side.

After the first few years of experimenting and development, today seems to be the ‘golden age’ of military robots. However, experts are recognizing potential developments and view today’s robots as a Ford Model T, as this is only one of the first stages of robot development within the military.3 More and more devices perform certain tasks automatically and are, in this way, able to substitute humans. If soldiers cannot be substituted completely, they move their position behind a computer from which their robot will be controlled.

V. Future military robots

The military will continue developing robots for their own purposes and will, therefore, find new purposes over and over again. Technological advances enable the developers to build new systems for more tasks. Unmanned ground vehicles will be of great value for such projects because they are already capable of managing several tasks: “A converted Humvee has already driven around military bases at an average of thirty-five miles per hour and never veered from its planned route by more than eight inches.”3

This capability would permit to send unmanned supply convoys, again minimizing human losses.

Another way to make military work safer is to send ground robots as pioneers instead of soldiers. Cameras transmit images of the scene, in order to give the soldiers an expectation of what lies ahead. This is not really new, but in the future, those robots will carry weapons and be able to perform a wider set of battlefield roles.3

Fig. 8. Packbots can be equipped in various ways for various purposes (science.howstuffworks.com)

One such robot already exists as a prototype. As small as a golf cart, the robot is controlled by a PlayStation video game controller or software plug-ins, which allows semi-automatic and fully autonomous modes. The fully equipped robot carries a machine gun, rockets, and non-lethal weapons. In total, the Gladiator will cost 400,000 Dollar.3

Ground robots are not only required to perform combat roles, as they will also be used as support for medics, who have one of the most dangerous jobs on a battlefield. The “Bloodhound” is one such robot; an improved version of the ‘packbot’, which is


134 AARMS 9(1) (2010)

able to find wounded soldiers and conduct simple treatments, such as checking his vital functions and giving morphine, for instance. Specially designed medbots will also be on board of evacuation vehicles and drag wounded soldiers into safety.3

Research on medical robots will be one of the major issues in future, as they are supposed to perform complex surgeries inside the armored vehicle. The Defense Advanced Research Projects Agency (DARPA), “has already spent more than $12 million on such a remote trauma pod”3 in order to reduce the risk for soldiers. This is based on existing robotic surgical systems and thus, the odds are good that it will be used in ten to fifteen years time.

Similarly to ground robots, the military also develops robotic devices for use at sea – unmanned surface vessels (USV), as well as unmanned underground vehicles (UUV). Conditions at sea are more challenging than at land, but the US Navy invests great amounts in the development of robotic boats and underground boats that will work as scouts, communicating with a mother-ship or as highly effective weapons.

The developments on ground and at sea will also be continued at air level. Boeing already presented its X-45 a few years ago. This project, to build an unmanned combat air vehicle (UCAV), was cancelled by the US Air Force in 2006, obviously because the drone was too good and came too soon. The Air Force had already spent $28 billion on the development of the fighter jets F-22 and F-35. However, it is said that the project has not been given up completely.3

The question of the direction in which robotic development might head in the future still remains. Experts believe that space could be a new battlefield. If a conflict zone develops in space, it has to be organized with unmanned devices, as it would be far too expensive to send humans, along with the necessary supplies and oxygen. “It costs roughly $9,100 a pound to launch anything into space with a Space Shuttle.”3 Thus, the first unmanned vehicles for the use in space are already in development. One of these “space ships” is Boeing’s X-37.

No matter what robotic developments will enter military work, they all have a common goal: to minimize human losses on their side and increase efficiency. Technological advances will always enable engineers to build new devices and, provided that they are creative enough, there will be a lot of innovations within the sector of the military robot.

V. Conclusions

History has shown that the military makes use of every innovation that has the potential to support military work. In ancient times, there were innovations, such as metalworking or gun powder; in modern times, robotic devices have become popular. If one product proves to be useful, development of it will be pushed.

Robotics’ experiences search for a push right now. The military has recognized that automatic devices are far more efficient than the use of human soldiers, as there is a reduced risk of mistakes and the devices can also be equipped with powerful weapons. The military has recognized another advantage, too: more and more robots can do dangerous work that was previously undertaken by humans. The use of robots for such tasks makes a soldier’s work much more secure; it can even saves lives.

Certainly, most nations try to avoid wars and battles but in order to achieve peace in conflict zones, a well prepared military is crucial. The realistic concept that the military still performs life-threatening tasks is reason enough to develop robots that will support soldiers on their missions.
