Self-replicating robots just around the corner?

05/11/2005 2:00 PM

Once the stuff of science fiction, researchers at Cornell University have built a machine that can replicate versions of itself. Each 10 centimeter cube contains a microprocessor with a set of instructions to build more cubes. Watching a video of the device in action, I must admit that it seems to just be a magnetic cube moving other cubes around, with more cubes "suddenly" appearing.

That's Great

Now all it needs is a way to power itself, random mutations in the reproduction process, and a few billion years.

Bacteria

05/11/2005 2:33 PM

Looking at this reminds me of bacteria or protozoa. Right now it might just be simple division, but reproduction is one of the simple criteria for deciding if something is alive or not. There are already robots that "eat" which is another criteria. I wonder if I'll see real artificial life (not intelligent life, just artificial) in my lifetime.

Video

I agree. The action in the video seems more like movement than replication.

The thing that makes it reproduction is that it takes pieces from it's environment to build copies of itself. If you notice it build exact replica's of it's self from the blocks. Now shrink it to nano size and change each block to carbon molecules and you can see why books like Prey by Crichton are so scary.
