The Crossing Robot Who Learned to Say Maybe
Every school morning, a tall, gleaming robot named Pim stood guard at the corner of Birch Street. Pim wore two lamps on its hat. A green lamp meant "go," and a red lamp meant "stop." For years, those two simple signals had been entirely sufficient.
Then came a foggy Monday. When Tamsin reached the corner, she could see nothing but gray. Pim's red lamp was glowing, yet its eyes were whirring in confusion.
"I cannot decide," Pim buzzed anxiously. "I see a shape far down the road. It could be a bus, or it could be a bush. Green is not correct, and red is not correct either."
Cars hummed somewhere in the mist, and a long line of children waited behind Tamsin, shifting their feet restlessly.
Tamsin dug through her backpack and found a yellow bottle cap and a roll of tape. She stood on tiptoe and fastened the cap to Pim's hat between the two lamps. Then she took a marker and drew a tiny eye on it.
"This lamp means look," she explained. "Look carefully, and only then make a choice."
Pim's sensors flickered, and a soft yellow glow spread across the hat. "Maybe," said Pim delightedly. "Maybe means look first."
Everyone looked closely. The shape was only a bush. Pim switched the light to green, and the children crossed together, listening for every car before they stepped.
