So here, you're going to see a thousand robots that are working together to self-assemble the letter K.
這里你們可以看到一千個機器人合作自發組成字母K。
The K is on its side. And the important thing is that no one is in charge.
完成后的字母位于上方。重要的是沒有一個機器人起指導作用。
So any single robot is only talking to a small number of robots nearby it,
每個機器人只和周圍的一些機器人交流，
and it's using its motion rule to move around the half-built structure just looking for a place to fit in based on its pattern rules.
它利用自身的運動規則，在建了一半的結構周圍運動，只是根據其樣式規律尋找一個合適的位置。
And even though no robot is doing anything perfectly,
即使沒有一個機器人的行為是完美的，
the rules are such that we can get the collective to do its goal robustly together.
這些規則卻足以使我們通過集體協作順利達成目標。
And the illusion becomes almost so perfect, you know -- you just start to not even notice that they're individual robots at all,
這種幻想近乎完美，你們甚至不需要注意到它們是個體機器人，
and it becomes a single entity, kind of like the school of fish.
它們變成了一個單一的實體，就像剛剛提到的魚群一樣。
So these are robots and rules in two dimensions, but we can also think about robots and rules in three dimensions.
這些是從二維層面看機器人及其運動規則，但我們也可以從三維的角度考慮機器人和規則。
So what if we could create robots that could build together?
如果我們能創造有建筑能力的機器人呢？
And here, we can take inspiration from social insects.
看看這里，我們從社會性昆蟲身上獲得了啟發。
So if you think about mound-building termites or you think about army ants,
如果你想到了白蟻丘或者是行軍蟻，
they create incredible, complex nest structures out of mud and even out of their own bodies.
它們用泥土甚至用它們自己的身體，創建了驚人復雜的巢穴結構。
And like the system I showed you before, these insects actually also have pattern rules that help them determine what to build,
就像我之前給你們展示的系統一樣，這些昆蟲實際上也有排布規則，可以幫助它們決定要建造什么，
but the pattern can be made out of other insects, or it could be made out of mud.
但是這種樣式結構也可以由其他昆蟲造出來，或者是用泥土。
And we can use that same idea to create rules for robots.
我們也可以將同樣的想法用于創建機器人規則上。
