The left and right front/hind legs moving in sync looks unnatural. I wonder if this is ultimately the best way to distribute weight and balance of a four-legged object, and why living four-legged creatures do not run like this?

Alternatively, would it be better if the robots also ran more life-like, or is there a benefit (besides the ease and simplicity of engineering the physics) to the robots running like this? I.e. will they ultimately have the robots running more life-like?

It speaks volumes about their engineering principles - KISS is alive and well at Boston Dynamics :)

Is this related to Boston Dynamics? The work looks very similar, of course, but I don't see their name associated to it. According to this article, Boston Dynamics has it's own "Cheetah" http://spectrum.ieee.org/automaton/robotics/robotics-hardwar...

MIT is probably developing advanced algorithms for the Boston Dynamics platform.

There's no reason that technological progress from the US government couldn't be driven by NASA rather than DARPA. I suspect many peace-loving people would prefer to see that.

Not enough peace-loving people to vote for a NASA-science-centric government vs the Military-Industrial government we already have.

I'd say that even if there was, that message wouldn't get through. There are many reasons that people vote for one party over another, there's nowhere on a ballot paper to indicate why the vote is being cast.

If you were running a political party, the most logical assumption to make (in the absence of richer feedback) was that the people that voted for you did so because they liked your manifesto and/or believed you'd be more competent than your competition.

With that in mind, an election doesn't really allow any meaningful influence on policy, it has to come in a different form (direct democracy, for example).

I'm not a US citizen, but from what I've read the laws on direct democracy are set at the state level, is that correct? Are there any mechanisms in place to propose policy changes at the federal level (aside from lobby groups in Washington)?

This reminds me of when i was learning to drive. In the beginning I was only aware of what was immediately in front of the car, and as such, drove very slow and had pay extra attention because a lot of important stuff was coming in to my field of view all the time. Now, when i drive i look further down the road, i plan out how to follow the road, i see the intersection coming up, and try to anticipate the routes of t…

Well, all the sensory overload you experienced as a novice driver has become background noise that is handled subconsciously now. That lets you focus on more strategic planning of your driving. That's one reason I like countries that mandate a learner sign in cars for new drivers. It lets others around them understand that they are still getting to grips with that sensory overload and allows them to act accordingly.

Well, it is very impressive, but still a very long way from what a real animal can do. What if the obstacle is at the edge of a canyon? It will suicide :D . Those tests are very restricted, but even after they will think the robot is ready, there will be cases they have missed in which it will fail.

Baby steps. A fully terrain aware robot will be very complicated. Breaking it down into discrete goals only makes sense.

Stuart Russel of AI a Modern Approach fame ( with Norvig ) asks us to consider the ethics of AI research - killer robotics, & hunter drones.

http://www.nature.com/news/robotics-ethics-of-artificial-int...

He calls for a moritorium until we can get a neural net to learn Asimov's 1st Law.

Should the self driving car swerve into you to avoid greater moral hazard ?

Humour aside as researchers and robotocists do we have a moral obligation to obey the 1st Law ?

That's how they run flat out. Do they alter their gait like horses, I wonder?

No one seems to be discussing how this can be improved! Here are a few points: 1. Real cheetahs don't run like that. The action of both pairs of legs is staggered for smoother motion and control. Check this out - https://www.youtube.com/watch?v=131wvVGjZUc 2. Looking at this jumping-over-obstacles video, it seems like the robot is lacking flexibility. The real life cheetah's hind legs go quite a bit underneath in pre…

Yeah! And whilst we're at it, wings on aeroplanes don't flap either. RUBBISH.
