Swarms of Microrobots Over Europe?
Roland Piquepaille writes "In 'Mini robots to undertake major tasks?,' IST Results describes a EU-funded project which allowed to build several kinds of microrobots in the last three years. These robots are very small (about 1.5 cm by 3 cm), have limited on-board intelligence and are wirelessly controlled by a central robot control system. A follow-on project has already started, with an even more ambitious goal: deploy 'real' swarms of up to 1,000 robot clients. Such robot swarms are expected to perform 'a variety of applications, including micro assembly, biological, medical or cleaning tasks.'

Well such an idea sounds reasonable enough. In fact in Richard Feynman's "plenty of room at the bottom" famous speech, he describes something similar: building small machines that are then used to build even smaller machines, until finally you have atomic-scale machines. This speech is considered by many to be the "original idea" for nanotechnology.
So why don't we have nanobots yet? Well it turns out its a little more complicated than that. The basic problem is that designs for large-scale robots do not work at smaller scales. You can take macroscopic engineering principles and scale them up or down to a point, but eventually they break down. The design of a 200ft long bridge is not just a 4X scale version of a 50ft bridge, after all.
If you read Drexler's technical book on the subject (Nanosystems) he goes into detail on how various properties (strength, elasticity, conductivity) scale down to the nano realm. Some of them scale favorably, whereas others do not. Thus nano-scale robots will not merely be "small versions" of macro robots. For instance the viscosity of a liquid becomes much more important than gravity, at small scales (whereas at large scales dealing with inertia and gravity are important).
My point is that robots cannot simply build exact (but smaller) copies of themselves. The half-sized robots will be useless within a generation or two, and will require new designs, optimized for that size. (Added to that, robot designs that are self-replicating are not trivial to begin with, at any size-scale!)
Roland Piquepaille and Slashdot: Is there a connection?
I think most of you are aware of the controversy surrounding regular Slashdot article submitter Roland Piquepaille. For those of you who don't know, please allow me to bring forth all the facts. Roland Piquepaille has an online journal (I refuse to use the word "blog") located at www.primidi.com [primidi.com]. It is titled "Roland Piquepaille's Technology Trends". It consists almost entirely of content, both text and pictures, taken from reputable news websites and online technical journals. He does give credit to the other websites, but it wasn't always so. Only after many complaints were raised by the Slashdot readership did he start giving credit where credit was due. However, this is not what the controversy is about.
Roland Piquepaille's Technology Trends serves online advertisements through a service called Blogads, located at www.blogads.com. Blogads is not your traditional online advertiser; rather than base payments on click-throughs, Blogads pays a flat fee based on the level of traffic your online journal generates. This way Blogads can guarantee that an advertisement on a particular online journal will reach a particular number of users. So advertisements on high traffic online journals are appropriately more expensive to buy, but the advertisement is guaranteed to be seen by a large amount of people. This, in turn, encourages people like Roland Piquepaille to try their best to increase traffic to their journals in order to increase the going rates for advertisements on their web pages. But advertisers do have some flexibility. Blogads serves two classes of advertisements. The premium ad space that is seen at the top of the web page by all viewers is reserved for "Special Advertisers"; it holds only one advertisement. The secondary ad space is located near the bottom half of the page, so that the user must scroll down the window to see it. This space can contain up to four advertisements and is reserved for regular advertisers, or just "Advertisers". Visit Roland Piquepaille's Technology Trends (www.primidi.com [primidi.com]) to see it for yourself.
Before we talk about money, let's talk about the service that Roland Piquepaille provides in his journal. He goes out and looks for interesting articles about new and emerging technologies. He provides a very brief overview of the articles, then copies a few choice paragraphs and the occasional picture from each article and puts them up on his web page. Finally, he adds a minimal amount of original content between the copied-and-pasted text in an effort to make the journal entry coherent and appear to add value to the original articles. Nothing more, nothing less.
Now let's talk about money. Visit http://www.blogads.com/order_html?adstrip_category =tech&politics= to check the following facts for yourself. As of today, December XX 2004, the going rate for the premium advertisement space on Roland Piquepaille's Technology Trends is $375 for one month. One of the four standard advertisements costs $150 for one month. So, the maximum advertising space brings in $375 x 1 + $150 x 4 = $975 for one month. Obviously not all $975 will go directly to Roland Piquepaille, as Blogads gets a portion of that as a service fee, but he will receive the majority of it. According to the FAQ [blogads.com], Blogads takes 20%. So Roland Piquepaille gets 80% of $975, a maximum of $780 each month. www.primidi.com is hosted by clara.net (look it up at http://www.networksolutions.com/en_US/whois/index. jhtml). Browsing clara.net's hosting solutions, the most expensive hosting service is their Clarahost Advanced (http://www.uk.clara.net/clarahost/advanced.php) priced at £69.99 GBP.
