Shades of Robert Heinlein’s 1943 short story, Waldo, and Richard Feynman’s 1959 talk, There’s plenty of room at the bottom, to the American Physical Society! Both of these texts feature the development of ‘smaller and smaller robotic hands to manipulate matter at the atomic and molecular levels’ and both of these have been cited as the birth of nanotechnology. The NanoHand Project (funded by the European Union) has developed microrobots designed to handle carbon nanotubes, according to the media release on Nanowerk News. From the media release,
The robots, about two centimetres in size, work inside a scanning electron microscope where their activities can be followed by an observer. “The whole set-up is integrated into the vacuum chamber of the microscope,” [Volkmar] Eichhorn [of the University of Oldenberg] explains. “There is a glass plate where these mobile microrobots can walk around.”
Each robot has a ‘microgripper’ that can make precise and delicate movements. It works on an electrothermal principle to open and close the jaws, much like a pair of tweezers. The jaws open to about 2 micrometres and can pick up objects less than 100 nanometres in size. “[It is] really able to grip micro or even nano objects,”
Eichhorn says. “We have handled objects down to tens of nanometres.”
If you go to Nanowerk News, you will be able to see a video of the microrobots in action or you can go to the NanoHand site here for more information.
“I don’t think you could say that innovation is deeply in the DNA of our Canadian business enterprises,” [John Manley] said, “We have built prosperity, up to and including this decade, on a fairly basic paradigm: we are rich in natural resources.” (from the article, Innovation isn’t in Canada’s DNA by Paul Wells in MacLean’s magazine here.) I agree more closely with Manley’s quote than I do with the article’s headline writer who seems to be implying that Canadians are not genetically disposed to innovation. Manley very specifically fingers business enterprises and not people. (I briefly mentioned the article in my July 31, 2009 posting in the context of a discussion[also in MacLean’s] by the big 5 Canadian universities about funding and innovation.)
