Killer robots can be taught ethics
Georgia Tech engineer develops "ethical governor" to help military robots decide when and who to shoot.
Adherence to the Three Laws of Robotics as put forth by Isaac Asimov has been, until now, entrusted to whoever held the joystick. That may change.
A robotics engineer at the Georgia Institute of Technology has developed an "ethical governor," which could be used to program military robots to actwhen deciding when, and whom, to shoot or bomb.
In one scenario, aspots Taliban soldiers, but holds its fire because they're in a cemetery--fighting there is against international .
In another, theidentifies an enemy convoy close to a hospital, but limits itself to shooting up the vehicles so as to avoid collateral damage to the hospital. The would also house a built in "guilt system," which would force it to behave more cautiously, after making a mistake.
While the work shows promise, it also draws attention to the inadequacy of trying to program machines with morals, especially ones expected to perform in a complex battlefield environment, according to experts.
"New Scientist. "Strict rules require an absolutist view of ethics, rather than a human understanding of different circumstances and their consequences."don't get angry or seek revenge but they don't have sympathy or empathy either," Noel Sharkey, a roboticist at Sheffield University, U.K., told
Arkin acknowledges that it may take a while before we can trust predators and other unmanned killers with life and death decisions.
"These ideas will not be used tomorrow, but in the war after next, and in very constrained situations." Arkin is quoted in New Scientist. "The most important outcome of my research is not the architecture, but the discussion that it stimulates."
