机器人能折出那只纸鸟吗

At a community workshop, Sam sets a small robot arm beside his grandmother's paper birds. The machine is part of his student project. He has programmed it to fold a square sheet in several careful steps. He hopes it will make the demonstration easier for visitors to follow.

在社区工坊里，萨姆把一只小机械臂放在奶奶的纸鸟旁。这台机器是他的学生项目。他编程让它分几步小心地折叠正方形纸张，希望这样更方便参观者看懂示范。

The first few birds look almost identical. Their wings meet neatly, and their noses point in the same direction. A visitor asks whether the robot will replace the people at the table. Sam starts to answer yes, then notices that his grandmother is smiling at a rather crooked bird.

最初的几只鸟看起来几乎一模一样。翅膀合得很整齐，鸟嘴指向同一个方向。一位参观者问机器人会不会取代桌旁的人。萨姆刚想说会，却注意到奶奶正对着一只歪歪的鸟微笑。

“A little girl made this one for her brother,” she explains. “She wanted one wing to look like his injured arm.” Sam looks again. What seemed like a mistake was actually a choice. The bird carries a meaning that his original instructions could not have predicted.

“一个小女孩为弟弟做了这只鸟。”她解释说，“她想让一只翅膀看起来像弟弟受伤的胳膊。”萨姆重新看了看。原以为是失误的地方，其实是有意的选择。纸鸟承载的意义是他原先的指令无法预料的。

For the afternoon session, Sam changes the activity. The robot prepares the first simple folds, and visitors finish their own designs. Some add long tails; others draw faces. His grandmother helps people turn their ideas into shapes, while Sam explains how the machine follows its instructions.

下午的活动中，萨姆调整了安排。机器人先折好简单的基础步骤，再由参观者完成各自的设计。有些人添上长尾巴，另一些人画上面孔。奶奶帮助大家把想法变成造型，萨姆则解释机器如何执行指令。

By closing time, the table is less tidy than before, but the conversation is livelier. Sam photographs the different birds for his project. He still values accurate folding. Now, however, he has another question to ask: accurate for which purpose, and useful to whom?

收工时，桌面比之前乱了，交谈却更热闹。萨姆拍下不同的纸鸟，作为项目材料。他仍看重准确的折叠，但如今又多了一个问题：为哪种目的准确，又对谁有用？

What seemed like a delay was actually useful thinking time.

看似耽搁的时间，其实是有用的思考时间。
