开源的机器人,大众的机器人(编译)

消息来源:Robots for the rest of usloving the machineIn Japan, robots are people, too

4月25号,卡内基-梅隆大学公布了一个新的项目,该项目可以帮助普通大众利用自己本地的硬件商店就可以构造一个属于自己的机器人。TeRK,即遥现机器人工具箱(Telepresence Robot Kit),由该大学机器人研究所一个副教授Illah Nourbakhsh开发,旨在机器人学的教育和普及的非营利项目。这是一个开源的项目,技术都是公开的。该项目的前身是Personal Rover Project,一些底层技术和论文主要都在这个项目中。TeRK得到了Google,Microsoft和Intel的资助。

TeRK的发音和TURK(土耳其)比较接近,大概有纪念第一个“机器人”,The Turk,的意思。1770年,正是工业革命开始之际,在维也纳一个叫Wolfgang von Kempelen的人发明一个可以自动下棋的机器,这就是著名的Turk,这个名字来自于机器上的那个木偶,他的穆斯林头巾和长袍。在18世纪末和19世纪初,Turk周游欧洲和美洲,打败了几乎所有的挑战者,震惊了所有的观众。事实上,这是一个骗局,箱子里有一个人在控制着机器。尽管如此,它还是算得上是机器人的遥遥先驱了。

在该项目中给出了“机器人制作方法(robot recipes)”教爱好者一步一步的DIY。看上去很easy。为了方便机器人的制作,该项目推荐使用一个叫做Qwerk的处理器,这是一个Linux计算机,自带了机器人控制软件和一大堆外设接口(比如可以控制4个发动机,可以使用usb,有网络适配器,可以无线上网),这个东东大概要花$350.

右图中那个是这个项目中代表性机器人,叫Qwerkbot,中间那个有很多孔的板子就是Qwerk处理器。这个机器人可以自动搜索无线网关并登录英特网,这样你可以在另一个地方通过网页浏览器控制它,让它四处游荡,并反馈信息(这就是这个项目名称中有“遥现”,Telepresence,的原因:让你感受到东西似乎就在眼前),恩,比如偷拍,嘻嘻(坏笑)。左图是叫做Flower的机器人,它的七个花瓣都可以动,它们可以感知身边物体的移动,甚至可以抓住一个轻量级的小球。

不过西方的机器人个个都有点弗兰肯斯坦(Frankenstein,又译“科学怪人”,玛丽·雪莱夫人创造的形象),虽然没有痛苦的灵魂,但都长着一副苦大仇深的样子,衣服也不穿,心肝脾肺肾都出来显摆。这一点日本机器人就亲民多了。




不过个人还是比较喜欢苦大仇深的类型,毕竟我一眼能看出这机器人大概干嘛的,日本的东东除了那个自动清洁机器人长得就是个吸尘器样子外,其它的真的不明白是干嘛的。

我为何而生

这是罗素在其自传前言中的一番话.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a great ocean of anguish, reaching to the very verge of despair.



I have sought love, first, because it brings ecstasy - ecstasy so great that I would often have sacrificed all the rest of life for a few hours of this joy. I have sought it, next, because it relieves loneliness--that terrible loneliness in which one shivering consciousness looks over the rim of the world into the cold unfathomable lifeless abyss. I have sought it finally, because in the union of love I have seen, in a mystic miniature, the prefiguring vision of the heaven that saints and poets have imagined. This is what I sought, and though it might seem too good for human life, this is what--at last--I have found.



With equal passion I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. And I have tried to apprehend the Pythagorean power by which number holds sway above the flux. A little of this, but not much, I have achieved.



Love and knowledge, so far as they were possible, led upward toward the heavens. But always pity brought me back to earth. Echoes of cries of pain reverberate in my heart. Children in famine, victims tortured by oppressors, helpless old people a burden to their sons, and the whole world of loneliness, poverty, and pain make a mockery of what human life should be. I long to alleviate this evil, but I cannot, and I too suffer.



This has been my life. I have found it worth living, and would gladly live it again if the chance were offered me.
