Robots Making Smaller Robots Making Smaller Robots

In his excellent 1937 short story A Menace In Miniature, Raymond Z. Gallun writes about two intrepid space explores who fight a deadly, tiny enemy. How can they possibly engage this enemy on its own microscopic turf?

They use their miniature robot Scarab - just a quarter of an inch long - to build an even tinier version of the Scarab robot. And so on.

With the Scarab as big as a beetle, I could make a Scarab as big as a sand grain. This second Scarab could build a miniature of itself, as big as a dust grain. The third Scarab could construct a fourth, bearing the same proportions as the first to the second, or the second to the third. And so on, down, to the limit imposed by the ultimate indivisibility of the atoms themselves.

But that's science fiction. How can you manufacture very small objects in the real world? Robotics Online had an interesting article this week about robots used for manufacturing. It turns out that one of the limits on the size of a manufactured item is the size of the smallest part that a human being can manipulate and position during assembly. Anything smaller than that, and you will need to have a robotic system for assembly.

Here are some examples of products that are not just better made by robots, but which cannot be built without robotic manipulators:

  • Nanotechnology robots are used for manipulating contacts, which are 100 nanometers in length and getting smaller. Robot operators are able to position a finely etched tungsten probe on the metal contact to achieve good electrical contact.

  • Typically, mass spectrometers are large and very expensive laboratory instruments. Using [the] nano-assembly approach, high-precision robotics are building miniaturized mass spectrometers... Smaller mass spectrometers are deployed at airports for security.
  • Miniature robotic production consists of disk drives, cell phones, and photonics. Micro-assembly gets down into the level of sub-semiconductors, placing subassembly components onto the chip themselves, and applications where tolerances are within a micron... Nanotechnology robotics has expanded into biological systems, where companies are manipulating cells within fluids.
One of the experts contacted in writing the Robotics Online article, Dr. John Randall, Chief Technology Officer at Zyvex Corporation, says that high technology can bring jobs back to places where human labor is costly.

"Products can operate that are a lot smaller than humans can manipulate. Manufacturers are afraid to make products any smaller because humans cannot handle them," Randall says. "Robotics come in by picking up and positioning parts that are a lot smaller than human hands can. This will lead to a new revolution in miniaturization, where things that have gotten very small can get a lot smaller. This could bring jobs back to the United States."

If you are interested in some of the speculations on nano robotics, take a look at Bush Robots - , fractal branching ultra-dexterous robots.

Update 09-Feb-2009: Also, take a look at this entry for the Christmas bush robot from Robert Forward's 1985 novel Rocheworld. End update.
