Robotics + Car = Hallucigenia
News for nerds writes "I4U has news about a new transportation concept, called The Hallucigenia 01, which is a working 1/5 scale vehicle prototype, designed by Japanese design firm Leading Edge Design. PC Watch (Japanese) has photos and movies. Its 8 wheels are independent robotic arms controlled by their own satellite CPUs, interconnected to the main CPU by an internal LAN."
It looks like a spider crossed with a skateboard. I wouldn't drive that.
Are they implying that the idea for the car came from a night spent tripping on acid.. or... ??
Why does it need to have multiple computers networked? Doesn't this add latency that could be very dangerous at high speed? Wouldn't one computer, rather than several, with the proper sensory and control hardware be a better choice? Will I only use question marks to end sentences in this post?
Do not look into laser with remaining eye.
Soon we will hear the deep voice of Darth Vader saying "I find your lack of bandwidth disturbing..."
Why did I think of that? I dunno, maybe it's because the car looks kinda like Darth's friggen head..
One of the central tenents of all good engineering is "As complex as is needed, and NO MORE." Any more you add after that point is just "more to go wrong".
Eight wheels, eight suspension systems, eight control systems. True, perhaps the system is designed with failure in mind, but think about owning this as a vehicle for normal use - how often will you be taking in to be fixed, because one or more wheels have broken?
It's just like the fools who buy 4 wheel drive SUVs when what they need is a minivan - now they have what amounts to a whole extra powertrain to go wrong.
Now, if the intent was for this to be used in unusual circumstances (forestry work, extreme rough road work or the like) I could believe this was "as complex as needed but no more".

It is a little animal found in the Burgess Shale of Canada. See the Stephen Jay Gould Book "Wonderful Life" for details. Here is a picture:

From looking at the pictures, it seems that the wheels can rotate perpendicular to the length of the vehicle. Should make parallel parking a breeze.
From looking at the videos, it does.
It also goes sideways, up and down a bit, and can walk (akwardly) on them 4 at a time.
Does all sort of crazy cool stuff.
You can't take the sky from me...
I don't know wheter this model can or not, and the wheels are toys in this model, but the think should be able to turn the wheels flat and use them as rubber feet and WALK over obstacles. I like the idea. Complicated gizmo, though.

Hallucigenia means "Dream Children" and is a name of a small worm belonging to the Burgess-Shale collection of fossils
Researcher Simon Conway Morris had probably been working overnight a little too often, since he mistook the fossil for an eerie monster-like creature with a blob like head and spikes for legs, thus dubbing it "Hallucigenia". See the picture. Looks a little bit like Alien, doesn't it?
It was only in 1991 that this strange little animal's anatomy was correctly interpreted as a worm, the Onychophore, with spikes on it's back and tentacles or, better, pseudopods for walking (and probably eating).
I wonder if the pictures of this car are upside down...
Hack your mind out of its sandbox.
Well, it does a great job of navigating over the rough terrain of that flat smooth table top. Whats the point again?
The ability to travel in one direction while independantly rotating in another (and it looks like this eight legged freak can do that to an extent) is called holonomic motion. Robotics people have been doing this for years with something called an omniwheel. Basically its a wheel that contains many other smaller wheels that roll perpendicular to the axis of the big wheel.

We can do holonomic motion with as little as three wheels (popularlized by the palm robots from carnegie melon). Of course, four wheeled models have been made.
And I really think that it is from the four omniwheel concept that will really revolutionize travel, not this eight legged, asking to break down, feat of engineering.
