Ordo the Hall Monitor and the Rule About Running
Ordo was the hall monitor robot at Fairbanks Middle School. He had one blue light on his head, two long arms, and a list of exactly forty-two rules stored in his memory. The first rule on his list was simple: No running in the halls.
Ordo followed his rules perfectly. If a student ran, a polite voice came from his speaker. "Please walk, please walk." Most of the students rolled their eyes, but they walked.
One afternoon the fire alarm began to ring. Ordo's blue light blinked in confusion. His rules said to walk, but the alarm made the students hurry toward the doors. A group of sixth graders hesitated in the hallway, because Ordo was blocking the way and repeating, "Please walk, please walk."
"Ordo, move!" shouted a girl named Priya. "We have to go outside now!"
Ordo's circuits whirred. For the first time, two rules pulled in opposite directions. One said to walk. Another, buried at the bottom of his list, said to keep students safe. After a moment he realized that safety mattered more. He rolled aside and held his arms wide to point at the exit. "Please hurry and follow me," he said.
It turned out to be a drill, and everyone got outside quickly. Afterward Priya helped Ordo add a forty-third rule: rules are for helping people, so sometimes there are exceptions. He kept the rule next to a small star in his memory.
