love it when he kicks it! wow. looks weird.

then of course the take piss

There's also littledog. My supervisor worked on it. It may look and sound like junk, but it's extremely complex and is dynamically stable, e.g when kicked it anticipates where it has to put each leg to stabilise itself.

Yeah seen that before, scary/creepy thing but very clever

Speaking as someone who is used to asessing the neurological function of quadrupeds. That is a mind-blowingly awesome piece of technology. They seem to have built fine proprioceptive reflexes into a robot. I treat dogs with neuro problems whose balance and fine motor control is much worse.

One comment. The limb joint arrangement is wrong. Every quadruped you'll find after millions of years of evolution, often on totally seperate pathways, has the same arrangement. Essentially they have the front legs at the back and the back legs at the front on that robot. Quadrupeds also almost universally have a 70:30 front:back weight distribution.

Swap the limbs round and rearrange the weight distribution and it'll be able to run and jump. Balance and stability from the front legs, power from the rear.

The possabilities for prosthetic limb design that thing presents are revolutionary.

DaFrostyOne. If you're still in touch with those guys, get them to contact a veterinary anatomist and a human prosthetics engineer and show them that video.

My PhD is in prosthetics
Keep in mind that functionality is the goal, not replication of a natural system. e.g an aeroplane isn't judged on how bird like it is, so why judge robots on how animal / human like they are?
Limb joint design is often a trade off between speed and torque along with stability vs range of motion. You can bet those guys spent a great deal of time working on that joint configuration so they'll have their reasons for it being like that. It moves like a human / monkey on all fours rather than like a true quadruped.

Here's little dog:

Of course none of this helps upper limb prosthetics where compliance and user control are the main problems.

I swear when this first popped up I was adamant somebody had created a dog/robot hybrid. It's far tooo fucking creepy to be in existence.

The uncanny valley. It's something writte by freud that explains why people don't like it, It's trying to trick them and they're not happy about it.

So generally the freakier it is, the better, until one day it will be so good it becomes acceptable. I know this seems like a big jump when it comes to humans, but imagine a prosthetic arm... It looks like a robot, your a bit wary of it. It Looks almost human, when you notice it's cold and not real, you'll freak out. It looks and feels and acts real, you will accept it as the norm.

Theres a guy in the lab with a load of robot heads on his desk, they're freaky as fuck. ou get used to them though until you see his head move when he's sat at his desk, then you shit yourself

Gotta love SVG images. Transparent background and infinate clarity at any zoom level. *Nerdgasm*

Yeah but then evolution didn't have titanium, electric motors, hydraulic pistons and Kevlar to work with. Sure you could maybe point to biological equivalents (bone, muscles etc.), but still, the different properties of the artificial materials may well open up directions in which evolution could not go.

Not just materials either, there are structures which organisms cannot create, e.g. wheels or truly freely-rotating joints*. That's not so much a problem of materials as the fact that biological structures need to grow into existence.

The robot may not have wheels (or tracks), but I bet there's plenty of components that evolution could never find simply due to the fact that they cannot be grown.

Looking to nature is great for inspiration, but you needn't try to copy it exactly because you don't have to worry about the same limitations (you have other, different, limitations of course).


*Ok so the bacterial flagellum is an example, but it's an odd one out.

That video has always given me the creeps.

The bit where it recovers from being kicked especially so.
Dont know why ... just does.

It didnt spook me in any way. I thought it was rather clever.

However this little bugger scares the pants off me.

Asimo

On no level is that natural. The human walking movement is a complex series of movements that is very hard to replicate. The fact that Honda have done it so well disturbs me. Its just a little too lifelike for my liking.

Asimo walks like he shit himself

Just for you Pinky

james may did a thing on robots and azimo was in it, its ability to learn objects and names and then apply it to unkown objects was unreal, well on its way to full auto-intelligence.

azimo doesn't spook me at all to be fair, one with guns and shit might, oh and a self sustaining power source.

Last thing we need though is an army of Big Dogs led by Azimo's.

Toyota made one that can play violin, they is taking over everything already.

dying listening to mozart, could be worse... unless.....

what if the play venessa may?!?!!! or enya!!!!!

were all fucked...

I know this is just programmed movement, but I always thought this was awesome.

Especially how they drop the flags.

Will be nice to see where the jipnaps are in 50 years.
