Robots are now helping passengers get through security faster. Seattle-Tacoma International Airport announced this week it is testing a robot to speed up the security process for passengers. The robot gives travelers tips for getting through security faster, like reminding them to remove objects such as scarves, light jackets, belts and to empty their pockets before going through screening. "The robot pilot program is an example of how Sea-Tac airport embraces technology, science and operational innovations," the airport said in a release. Sea-Tac officials will track the number of times travelers set off the body scanner alert during and after the robot test to see if it is actually helping speed up the process.
