It sounds like something out of a sci-fi movie U.S. researchers have given robots the ability be to be deceptive.
"We have developed algorithms that allow a robot to determine whether it should deceive a human or other intelligent machine and we have designed techniques that help the robot select the best deceptive strategy to reduce its chance of being discovered," said Ronald Arkin, a professor in the Georgia Tech School of Interactive Computing, in a release about the study.
The researchers taught a robot how to recognize when a situation warrants the use of deception, then programed it to behave appropriately.
They ran 20 hide-and-seek experiments with robots and markers. In one case, one robot would intentionally knock down a marker in such a way that make it look like it had gone one way, when in reality, the robot had hidden itself in a box.
"The hider's set of false communications was defined by selecting a pattern of knocked over markers that indicated a false hiding position in an attempt to say, for example, that it was going to the right and then actually go to the left," research engineer Alan Wagner said.
The hider robots were able to deceive the seeker robots in 75% of the trials.
The robots were only unable to hide when they failed to knock over the correct markers to deceive anyone following them.
The researchers said the study which was published this week online in the International Journal of Social Robotics will help in places like a
battlefield, where a robot can deceive an enemy soldier by creating a false trail, then hide so it will not be caught.
The researchers also said in a search-and-rescue operation, a robot may need to deceive in order to calm or get co-operation from a panicking victim.
"Most social robots will probably rarely use deception, but it's still an important tool in the robot's interactive arsenal, because robots that recognize the need for deception have advantages in terms of outcome compared to robots that do not recognize the need for deception," Wagner said.
