An elementary school in Tokyo has hired a 3.2-foot, 66-pound yellow guard robot to protect against baddies... and more importantly, it can scan students.
Get within 13 feet of the lovable robotyke, and it'll hold out its hand to ask for
retina scan and blood sample your school ID that has an imbedded IC chip. Once inspection is passed, the guard greets you by name and informs your teacher that you're on your way. Don't have an ID? Stay there while it calls a staff member. Don't try to escape its intimidating authority—the Japanese put cameras in their roboguards.
