Imagine a guard robot trying to apprehend an intruder or catch an escaped prisoner. Instead of simply tracking the target, ideally the robot would know how to creep up stealthily, by crouching behind objects and hiding in the shadows. This way, it could surprise and apprehend its target before it can get away.

Professor LEE Beom has created an algorithm that models just this sort of stealthy behavior. Lee's team designed simulations in which a robot waits in the shadows and moves quickly between obstacles to intercept a target.

The simulations take into account the size of the robot, the size of objects it can hide behind and the speeds of moving target.

Professor Lee said that his development can contribute to the commercializing of this kind of robots.

He presented the algorithm at International Conference on Robotics Automation(ICRA) on May 2009 at Kobe in Japan hosted by IEEE.
