TED演讲:我们能让物体自动化组装吗?(3/3)
【TED】是一个会议的名称,它是英文technology,entertainment, design三个单词的首字母缩写。它是社会各界精英交流的盛会,这里有当代最杰出的思想家,这里有当代最优秀的科学家,这里有迸TED发着最闪耀的思想火花,这里孕育着最光辉的梦想。 【本节目每天更新,欢迎订阅。】 So these are the brilliant scientists, engineers, designers that worked on this project. And I think it really brings to light: Is this really scalable? I mean, thousands of dollars, lots of man hours made to make this eight-foot robot. Can we really scale this up? Can we really embed robotics into every part? The next one questions that and looks at passive nature, or passively trying to have reconfiguration programmability. _______(一句话听写,首字母大写,填填看)_________ It basically embeds the most fundamental building block of computing, the digital logic gate, directly into your parts. HINTS: computation But it goes a step further, and it tries to have actual computation. 有许多杰出的科学家, 工程师,设计师为这个项目工作。 我认为这一项目真的揭示出: 这真的可扩展么? 我是说,花费数千美元许多人时 来制造这个八英尺的机器人。 我们真的能扩大它么?我们真的能在每个部分中都嵌入机器人么? 下一个问题是 看看被动性, 或被动地尝试让重组具有可编程性。但它更进了一步, 它尝试进行实际计算。基本上嵌入了多数计算的基础构建模块, 数字逻辑门, 直接进入各个部分。 try to 尝试做sth. 这篇材料你能听出多少?点击这里做听写,提高外语水平>>

TED演讲:圆球机器人的舞蹈
【TED】是一个会议的名称,它是英文technology,entertainment, design三个单词的首字母缩写。它是社会各界精英交流的盛会,这里有当代最杰出的思想家,这里有当代最优秀的科学家,这里有迸发着最闪耀的思想火花,这里孕育着最光辉的梦想。 Péter Fankhauser : Péter Fankhauser is the leader of a team of students working on Rezero, a robot that balances on a single sphere. 【本节目每天下午2点更新,欢迎订阅。】 【全文听写】 HINTS: Rezero constantly toppling axis instability dynamically You might ask yourself, what's the usefulness of a robot that's unstable? Now we'll explain that in a second. Let me first explain how Rezero actually keeps his balance. Rezero keeps his balance by constantly measuring his pitch angle with a sensor. He then counteracts and avoids toppling over by turning the motors appropriately. This happens 160 times per second, and if anything fails in this process, Rezero would immediately fall to the ground. Now to move and to balance, Rezero needs to turn the ball. The ball is driven by three special wheels that allow Rezero to move into any direction and also move around his own axis at the same time. Due to his instability, Rezero is always in motion. Now here's the trick. It's indeed exactly this instability that allows a robot to move very [dynamically]. Let's play a little. You may have wondered what happens if I give the robot a little push. In this mode, he's trying to maintain his position. 你也许好奇,一个连站都站不稳的机器人 有什么用呢? 稍后我回解释 首先先解释下它是如何 保持平衡的 Rezero通过一个传感器不停地检测倾斜度 来维持自身平衡 它将通过适量转动马达 来抵消倾斜的角度防止倾倒 这个过程每秒要进行160次 稍有差错 它就会立刻摔倒在地 要运动和平衡 Rezero就得转动球 这个球是由三个特殊的轮子驱动 从而它TED能在各个方向上运动 并同时能够 自转 由于其不稳定性,所以它必须一直处于动态 妙就妙在这里 正是这种不稳定性 赋予了它动态性 让我们看看 如果我推它一下 会有什么反应呢 这个模式下 它会尝试 回归原位 这篇材料你能听出多少?点击这里做听写,提高外语水平>>

TED演讲:大人能从小孩身上学到什么(3/4)
发着最闪耀的思想火花,这里孕育着最光辉的梦想。 Adora Svitak A prolific short story writer and blogger since age seven, Adora Svitak speaks around the United States to adults and children as an advocate for literacy. 【本节目每天下午2点更新,欢迎订阅。】 【全文听写】 Hints: Okay Aristotle "The Wheels on the Bus Go Round and Round" "Pioneer Germ Fighters"(出现两次,第一次出现时无需加双引号或大写) Regimes become oppressive when they're fearful about keeping control. And although adults may not be quite at the level of totalitarian regimes, kids have no, or very little say in making the rules, when really the attitude should be reciprocal, meaning that the adult population should learn and take into account the wishes of the younger population. Now, what's even worse than restriction is that adults often underestimate kids abilities. We love challenges, but when expectations are low, trust me, we will sink to them. My own parents had anything but low expectations for me and my sister. Okay, so they didn't tell us to become doctors or lawyers or anything like that, but my dad did read to us about Aristotle and pioneer germ fighters when lots of other kids were hearing "The Wheels on the Bus Go Round and Round." Well, we heard that one too, but "Pioneer Germ Fighters" totally rules. 当政体害怕统治失控时,它就会变得暴虐。虽然大人可能不会像独裁政权一样心狠手辣,但小孩在制定规则方面是几乎没有话语权的。而正确的态度应该是两者相互尊重的,也就是说成人群体应该了解并认真对待年幼群体的愿望。 然TED而比限制更糟糕的是,大人常常低估小孩的能力。我们喜欢挑战,但假如大人对我们期望很低的话,说真的,我们就会不思进取。我自己的父母对我和姐姐抱很高的期望。当然,他们没有让我们立志成为医生或律师诸如此类的,但我爸经常读关于亚里斯多德和先锋细菌斗士的故事给我们听,而其他小孩大多听的是《公车的轮子转呀转》。其实我们也有听这个,但《先锋细菌斗士》实在是比那个强多了。 这篇材料你能听出多少?点击这里做听写,提高外语水平>>

TED演讲:贫穷,金钱,爱(3/5)
成了我的一个转折点 变TED成了一种交易 我是在购买什么东西 我是在购买我继续生存 且不被这些糟糕新闻烦恼的权利 我认为我们采用的这种方法,有时候 首先能够 让一部分人或者一些个体灵魂出窍 这种想法也能够变成一种商品 一种令人恐怖的东西 就是正如我所说所想 我们好像在购买我们之间的距离 我们好像在购买我们继续生活的权利 我想这种交易事实上阻碍了我们得到我们最想得到的东西 阻碍了我们的愿望 就是给予对他人真正有意义和有用的东西 即,去爱 这篇材料你能听出多少?点击这里做听写,提高外语水平>>

TED演讲:贫穷,金钱,爱(1/5)
有的 ,我还学到了, 我们这些五六岁的孩子应TED该做的是 很明显,去帮助 这也是耶稣需要我们做的。 他还说,你为他们做的就是为我做的 。现在, 我被极大的鼓舞了 ,我非常热切地希望自己能向世界证明自己的意义 ,相信我们都有这样的感觉。 此外,有意思的是上帝也需要帮助 。那对我来说真是个新闻 而且,这是貌似一个很重要的事情值得我们参与 。 这篇材料你能听出多少?点击这里做听写,提高外语水平>>
