A robot has been tested at Seattle-Tacoma International Airport to help passengers prepare for security checks. Through audio instructions in English and on-screen animated instructions in six different languages, the robot reminded passengers to remove items such as scarves, light jackets and belts and empty their pockets before going through screening.
For the pilot program, Sea-Tac officials tracked the number of times passengers triggered the body scanner alarm during and after the robot test. The technology augments the work of human beings, allowing them to spend more time on critical security tasks.
