“I agree with Ron that autonomous robot fighting machines look like an inevitability in the near future,” he told NewScientist.Īrkin’s work shows the inadequacy of our existing technology at dealing with the complex moral environment of a battlefield, says Sharkey. Roboticist Noel Sharkey at Sheffield University, U.K., campaigns for greater public discussion about the use of automating in war. “These ideas will not be used tomorrow, but in the war after next, and in very constrained situations.” Public Debate

However, he maintains that the development of machines that decide how to use lethal force is inevitable, making it important that when such robots do arrive they can be trusted. “The most important outcome of my research is not the architecture, but the discussion that it stimulates.” army, is not designed to develop prototypes for future battlefield use. But they gloss over the complexities of getting robots to understand the world well enough to make such judgments, he says something unlikely to be possible for decades.Īrkin stresses that his research, funded by the U.S. Simulations are a powerful way to imagine one possible version of the future of combat, says Illah Nourbakhsh, a roboticist at Carnegie Mellon University, Pittsburgh, U.S.
“I can easily make a robot do that today, but instead we should be thinking about how to make them perform better than that,” Arkin says. One Vietnam veteran told him of soldiers shooting at anything that moved in some situations. In developing the software, he drew on studies of military ethics, as well as discussions with military personnel, and says his aim is to reduce non-combatant casualties. Arkin has also built in a “guilt” system, which, if a serious error is made, forces a drone to start behaving more cautiously. Here the ethical governor only allows fire that will damage the vehicles without harming the hospital. In another scenario, the drone identifies an enemy vehicle convoy close to a hospital. Its maps indicate that the group is inside a cemetery, so opening fire would breach international law. forces in Afghanistan in 2006, the drone identifies a group of Taliban soldiers inside a defined “kill zone.” But the drone doesn’t fire.
In one scenario, modeled on a situation encountered by U.S. troops, using real maps from the Middle East. He is particularly interested in how such machines might be programmed to act ethically, obeying the rules of engagement.Īrkin has developed an “ethical governor,” which aims to ensure that robot attack aircraft (like the Predator, pictured, right) behave ethically in combat, and is demonstrating the system in simulations based on recent campaigns by U.S. But robotics engineer Ron Arkin at the Georgia Institute of Technology, Atlanta, is working to imagine wars in which weapons make their own decisions about wielding lethal force. Technology has always distanced the soldiers who use weapons from the people who get hit.

As military reliance on drones, guided missiles and other high-tech, unmanned agents increases in the coming years, scientists are exploring ways to incorporate ethical constraints and “rules of engagement” into the programming software that drives these robotic weapons.Ĭan a military robot, in essence, learn to behave by the Code of Chivalry? And, perhaps more relevantly, what does trying to program a machine with battlefield ethics teach us about our own sense of chivalry in combat? This article, reprinted from the popular scientific journal The NewScientist, gives some intriguing insights into chivalry’s place in warfare in the 21st century. This code mandates things like respect for combatants who surrender, reasonable measures to avoid harming non-combatants, and avoidance of weapons (from crossbows to poison gas) that are considered inhumane.Īpplying the ethical rules and restraints of chivalry in the heat of battle is one of the greatest challenges faced by soldiers today - and that challenge gets even greater when the soldiers in question aren’t human.
The truth is, soldiers today are governed by an ethical and moral standard that traces its lineage directly to the Code of Chivalry of the medieval knights. After all, we are regularly told that “all’s fair in love and war,” and yet we know chivalry is all about being fair and respectful to others. “Chivalry” and “warfare” are two concepts that sometimes seem to be at odds.
