One of my favorite chapters to write in Bogus to Bubbly was the one about nanotechnology. It was great to finally hand over the spotlight to those wondrous tiny robots that melted the Armory, “cured” Zane’s brain, and built half of Aya’s city.
But since I handed in B to B a few months ago, there have already been some cool new developments in the world of nanos. Here’s a three-legged, crab-walking microbot developed in South Korea. It’s made of a polymer (like plastic), but it’s powered by rat heart tissue. (Eww. But you can’t beat evolution for power sources, I guess.)
Watch it go:
You can really see the heart tissue dynamics in the way it moves.
Pros: It managed to walk for more than a week on one charge of rat heart.
Cons: It only went 50 meters in that week, giving it an average speed of 0.0002 MPH. But if your nanobot was walking around inside something really tiny like, say, a brain cell, this would be plenty fast.
Note that this robot isn’t proper nanotech, because it’s more than a millimeter across. (Your fingernail is about a millimeter thick.) Proper nanobots will be between 1 and 100 nanometers across, at least a thousand times smaller.
But from big things, little things grow.
And don’t forget that Justine and I will be in Toronto, Ontario Monday night:
