Engines of Creation: Solar Electric Robot Chariots!


Roman emperors fancied chariots back in the day.

Makes sense…

Our upcoming Robot Overlords would do the same.

[via Infoniac] By harnessing solar power the robot is able to move its two front legs to which rollerblades are attached with the back featuring two large wheels that keep the chariot rolling. It would be worth noting that solar energy is the main source of power for the machine.

The autonomous movement became possible thanks to cameras that ensure a safe and eco-friendly ride around a city.

The words ‘autonomous movement’ and ‘robot’ are just not made for each other, and should not be joined together through an unholy monstrous- union by any means!

But since it gets its power only through solar energy?

Weakness there!

Weaknesses…

Definitely when it comes to the possibility of life extinguishing technology?

Something that should always be observed, noted…

And printed in comic book form.

After all, all those ‘DARR Resistance pamphlets’?

Can get a little preachy.

And who like that?

[via io9] “Grey goo” is a term coined by Eric Drexler in his 1986 book about nanotechnology, Engines of Creation. In one section of the book, Drexler speculates about what could happen if we created self-reproducing “nanobots.” If they got out of control, they could conceivably use the resources of the entire planet to replicate in an exponential manner akin to bacterial replication. Every living creature, every useful mineral, would be converted into more of the “gray goo.”

This point of view was no doubt informed by the concept of Von Neumann probes, a method of interstellar exploration wherein a single, self-sufficient craft is sent out programmed with the ability to reproduce itself once it finds enough resources. One craft becomes two, which then becomes four, each going in different directions and communicating back with Earth, until the universe is mapped by a phenomenal number of self-reproducing spacecrafts. Regardless of the origin of the concept, the idea of grey goo quickly became fodder for science fiction writers and end-of-the-world scenarios in pop culture.

The question is, could a grey goo scenario really come to pass?

How would the nanobots replicate?

Theoretically, it is believed that these nanobots would replicate through the manipulation of individual atoms in a discrete manner to create a desired product. This is a technology we are far from accomplishing, but the goal of many researchers. The rate of reproduction would be rather quick if the technology was available, akin to the exponential replication seen with bacteria. There are some problems with self-assembly on the atomic level, however, with Drexler himself pointing out some of them in his paper Safe Exponential Manufacturing:

The chemistry proposed for machine-phase systems requires that every atom of every molecule be in a known position. A high-entropy mix of polysaccharides, proteins, lipids, and water, such as a biological material, does not meet this constraint, and hence would not be a suitable input. An MNT mechanochemical system would instead require as inputs simple chemical feedstocks, such as acetylene or acetone, in which every molecule is identical and impurities are easy to recognize by their shape and size.

Problems with self-replicating nanobot assemblers

So if they do go on a self-replicating frenzy, the nanobots simply won’t have access to enough viable energy sources. Organic life forms lack the degree of organization and orientation necessary for a situation by which a nanobot could simply “pluck” a necessary atom off of a wiggly lipid in a bilayer. If our oceans were made of an organic solvent like acetone, with little or no impurities, we would be in trouble, but instead, our land and sea environments have enough diversity on an atomic level to prevent their assimilation.

Also, it’s currently unknown as to what these nanobots would be made of – carbon would play some role, but if they were to made of a metal alloy like steel, there would be problems. Steel, though prevalent in industrial manufacturing, is a complex mixture of iron, chromium, tungsten, vanadium, manganese and a small amount of carbon. Any impurities in steel, as would theoretically occur in the process of nanobot assembly – say a small amount of copper is added – would greatly decrease the strength and durability of the steel. Steel in just one example, as there would be a variety of materials theoretically necessary for nanobots to reproduce.

  1. Such a cool post. The solar electric robot chariots, I almost like them. Oh, I could see myself going on their side. “weeps” how weak I am.
    Little of the fever, nice shiny new wheels and weakling that I am, I became the Darth Ninja. All with nice dark, metallic helmet. And You know how much I love my helmet, almost like I love chicken.

    I would really like to see how nanobots will self reproduce but if it is possible on the different planet, just in case.
    Great post, I enjoy it very much.

    • Dude…You are so weak! If you wouldn’t let me go over to the darkside for the promise of a pizza printer, no way am I letting you succumb for a chariot. I have my standards. :D

      • Haha
        Now that you remanded me ,I remember the pizza printer :D and yes, I kept you on this side.
        Good thing I did so you could save me. :P
        It is amazing that you remember that old post. “thumbs up”

      • I was teasing you. I understand what you are saying. I am similar. I remember things that I don’t need to or totally obscure things.
        But it is fun. I never know what will show up in this head of mine.
        We have tad bit weird minds. ;) I can’t listen to the repeated story per example. I remember everything what person said first time. The same with the visual stuff. I never watch movie twice but I can see it in my mind eye.
        I guess that is a reason I get bored easily. I need new informations constantly. Weird.
