Robo and the Lost Tooth
At bedtime, Mia wiggled her wobbly tooth, and out it popped! "Grandma will want to see it!" she said. But the tiny tooth slipped from her fingers, bounced on the rug, and rolled away, far under the bed. Mia peered into the dark. "I'll find it in the morning," she sighed, and climbed into bed.
When Mia was asleep, Bit and Lulu slid down from the windowsill to the floor. Under the bed it was dark and huge. A slipper stood like a mountain, and a sock made a soft cave. Far, far away, something small and white shone. "The tooth!" whispered Lulu. But it was much too far, and much too heavy for them.
At the edge of the toy box sat Robo, Mia's little toy robot, with two wheels and one claw. "Robo can fetch it!" said Bit. He pressed Robo's button. Nothing happened. Then Lulu found a little door in Robo's tummy. Inside glowed tiny lamps and a tiny golden track. "Robo has a little Glowtown inside him!" gasped Bit.
A Sparkling peeped out of Robo's little door. "Robo can't think for himself," it said. "He does just what the cards say, one card at a time, from the top." It showed them the cards. A straight arrow meant one step forward. A curved arrow meant turn left. A claw meant grab. "The cards in a row are Robo's program," said the Sparkling.
"Easy!" said Bit, and he slid in the cards quickly. Forward, forward, forward, grab. Robo whirred and rolled. One step, two steps, three steps, bonk! He bumped right into the slipper mountain. His claw closed, and he grabbed the slipper's fluffy pompom. Lulu giggled. "That's not a tooth!"
"Silly Robo," said Bit. But the Sparkling shook its head. "Robo did just what the cards said," it said kindly. Lulu looked at the cards, then at the floor. "Robo isn't silly," she said. "The cards were wrong. The tooth isn't straight ahead. We have to turn!"
This time Bit went slowly. Forward, forward, turn, forward, grab. Inside Robo, the Sparklings read each card and a little light moved down the row. Robo rolled two steps, turned, and rolled one more. His claw closed, and he grabbed a lost blue button. The tooth shone just one step away.
"One more step," said Lulu, and she slid one more forward card into the row, just before the claw. Far above, the window began to turn grey. Morning was coming! "Ready, Robo?" whispered Bit. Robo's lamps blinked, one, two, three.
Forward, forward, turn, forward, forward, grab. Robo rolled, turned, rolled, and stopped. His little claw closed gently around the tooth. "Got it!" cheered Bit. Even the Sparklings inside Robo did a happy dance.
"Now we need cards to come home," said Lulu. They laid them out together. Turn around, then the same steps back. Robo rolled the tooth all the way to the edge of the bed. There, Glitch was waiting. "I can fly it up!" she said, and she carried the tooth softly up to Mia's pillow.
In the morning, Mia opened her eyes, and there was her tooth, right by her pillow. "My tooth!" she cried. "Grandma, look!" And in the toy box, Robo sat very still, with a fluffy pompom and a blue button beside him.
That night, Bit lay in bed and thought. "Robo doesn't think. He just does the cards, one by one, from the top. And when the cards are wrong, we fix them." He smiled. The cards were tucked in Robo's drawer for next time. "But how will Robo remember them?" Bit wondered, and he fell asleep.
罗博和丢了的牙
睡觉前，米娅晃了晃那颗松松的牙，它一下子掉了出来！“奶奶一定想看看！”她说。可是小小的牙齿从她手指间滑了出去，在地毯上弹了一下，一直滚到了床底下最远的地方。米娅往黑乎乎的床底下看了看。“明天早上再找吧，”她叹了口气，爬上了床。
等米娅睡着了，比比和露露从窗台上溜下来，一路爬到了地上。床底下又黑又大。一只拖鞋像一座大山，一只袜子像一个软软的山洞。在很远很远的地方，有一个白白的小东西在发亮。“是牙齿！”露露小声说。可是它太远了，对他们来说也太重了。
玩具箱边上坐着罗博，他是米娅的小玩具机器人，有两个轮子，还有一只小夹子手。“罗博能把它拿回来！”比比说。他按了按罗博的按钮，什么也没发生。这时，露露在罗博的肚子上找到了一扇小门。里面亮着小小的灯，还有一条小小的金色轨道。“罗博的身体里，也有一个小小的发光城！”比比惊呼。
一个小火花从罗博的小门里探出头来。“罗博自己不会想，”它说，“卡片上画什么，他就做什么，一次一张，从上往下。”它给他们看卡片：直直的箭头，是往前走一步；弯弯的箭头，是往左转；小夹子，是夹起来。“一排卡片，就是罗博的程序，”小火花说。
“这太简单啦！”比比说着，飞快地插好了卡片：往前，往前，往前，夹起来。罗博呼呼地转起来，往前走。一步，两步，三步，咚！他一下撞在了拖鞋大山上。小夹子一合，夹住了拖鞋上毛茸茸的绒球。露露嘻嘻地笑：“那可不是牙齿呀！”
“罗博真笨，”比比说。可是小火花摇了摇头。“罗博是照着卡片做的呀，”它温和地说。露露看看卡片，又看看地上。“罗博不笨，”她说，“是卡片错了。牙齿不在正前面，我们得转个弯！”
这一次，比比慢慢地放卡片：往前，往前，转弯，往前，夹起来。在罗博身体里，小火花们一张一张地读卡片，一盏小灯沿着卡片往下移。罗博走了两步，转了个弯，又走了一步。小夹子一合，夹住了一颗丢了的蓝色纽扣。牙齿就在前面一步的地方发着光。
“再走一步，”露露说着，在小夹子前面又插进了一张往前的卡片。在高高的上面，窗户开始发灰了。天快亮了！“准备好了吗，罗博？”比比小声问。罗博身上的小灯眨了眨，一，二，三。
往前，往前，转弯，往前，往前，夹起来。罗博走了，转了，又走了，停了下来。他的小夹子轻轻地夹住了牙齿。“拿到啦！”比比欢呼。连罗博身体里的小火花们都跳起了开心的舞。
“现在我们要放回家的卡片了，”露露说。他们一起把卡片摆好：先掉个头，再照着原来的路走回去。罗博把牙齿一路送到了床边。小故障正在那儿等着。“我可以飞上去！”她说着，轻轻地把牙齿送到了米娅的枕头边。
早上，米娅睁开眼睛，她的牙齿就在枕头边上。“我的牙齿！”她高兴地叫起来，“奶奶，快看！”在玩具箱里，罗博一动不动地坐着，身边放着一个毛茸茸的绒球和一颗蓝色的纽扣。
那天晚上，比比躺在床上想呀想：“罗博不会自己想，他就是照着卡片，一张一张，从上往下做。卡片错了，我们就把它改对。”他笑了。卡片都放进了罗博的小抽屉里，下次还能用。“可是，罗博要怎么记住它们呢？”比比想着想着，就睡着了。
