Don't worry, if you're a world-class runner you can outrun this mean quadruped

For those who fear that one day our robotic contraptions may turn on us, you may have felt cold chill when witnessing the Defense Advanced Research Projects Agency (DARPA) funded "Cheetah" -- a headless robotic quadruped by Boston Dynamics.  But at least Cheetah -- faster than any human at speeds of 26 miles per hour -- was constrained to a tether. 

Well, your worst nightmares have now been realized as Cheetah is now running free as a next generation model dubbed "WildCat".  

The good news is that the untethered robotic cat (which bears a vague resemblance to the Transformer robot "Ravage") isn't quite as fast.  WildCat is capable of galloping or bounding gates at speeds of up to 16 miles per hour, where as the the fastest human can reach speeds of 27.79 miles per hour (with Olympic training).

The bad news is that WildCat can cover a mile in just 3 minutes and 45 seconds.  That's faster than any American alive today or any human for that matter, save three men -- Morocco's Hicham El Guerrouj, who holds the world record for running a mile in 3 min 43.13 seconds; Kenyan Noah Ngeny (3:43.40); and Algerian Noureddine Morceli (3:44.39).


Cheetah and WildCat are produced by Boston Dynamics, a small defense contractor that was a spinoff of Professor Marc Raibert's university "Leg Lab".

Presumably the new war robot could used for hauling soldiers gear through dangerous battlefields, or as a terrifying tool to kill "enemy combatants", particularly if the speed can be bumped up closer to its predecessor.

They say it can be used to haul stuff but, how does it compare to a pack mule? The tech is promising though. I could see packing comm gear on this things and sending it off to a hill or mountain top to relay signals down into the valleys or use as an ISR asset. Nice little remote detonation feature to keep the baddies from getting it.

Good question! if you take a running lawn mower with you when you pack into the wilderness this would be ideal.

Good question. I'd say the pack mule has the plus of feeding itself, while you need to carry fuel for the robocat. But the robocat has the plus of you being able to control it, while the mule* pretty much does as it pleases.

Mules tend to die when you shoot them, this will have armor. It's a battlefield tool, not to take on a camping trip to carry your stuff.

Thats good, if the bad guys shoot at the mule instead of soldiers it gives the soldiers a heads up.

Pack mules can carry a lot of weight. I guess you could armor one up and it still feeds itself.

So instead of making an artificial mule, we get a real one pump it full of steroids making it the Lance Armstrong of donkeys so it can carry more, armor it up like Iron Man to protect it from bullets, and then control it like a drone with some kind of mind control. Mybe this? http://www.bbc.co.uk/news/business-23994649

It would probably be cheaper and we will be called UPS - Unmanned Pack-mule System

I've seen that one. Pretty cool. Now, don't get me wrong, I think the tech is great, and it has it's uses. As a pack mule, it's not there yet, but it's coming along pretty well. The speed from the wild cat is cool, but the purpose of legs is to allow it to move over terrain that would give wheeled vehicles trouble. I want to see this thing run on some rough terrain, not a parking lot.

Ok so a human is faster…in the short run. How many 3 minute miles can this thing do in a row. How many consecutive 3.43s can a human run? A cheetah is a sprinter and has to quit as its body temp rises a hyena runs slower but further. Each sort of performance style has its place this should have been called a hyena.

What mars is asking though, is how long can those humans run faster? The Wildcat can run at that speed for as long as it has fuel to power it.

Those three humans that can run a mile in under 3:45, can they maintain that speed over 2 miles, 5 miles, 10 miles, 20 miles? My guess is, best case scenario they can maintain those speeds for a couple miles. After that, the fatigue is going to be too much and Wildcat will quickly catch up.

Using small, reliable and proven 2-cycle engines is common for industrial testing before machines are fitted with more exotic or expensive options like lithium/hydrogen, which this will likely end up with in order to be silent. But the power source has little importance at this stage...although it looks like they're concept is solid so it might be time to move onto packaging and finesse.

I've loved following this "dog" over the years. It's fun to see it out in the wild and not on a conveyor belt anymore.

Not copying nature.

I think the front legs are the wrong way around. I had wondered why mammals have their feet the way they are, and now, when we build a robot that has them different we can see why cattle, horses, sheep, goats, dogs, etc were created the way they are. This thing looks like it's front heavy, but I think that's just because the front hooves seem to spend most of the time touching the ground behind the shoulder, the equivalent of reducing the "wheel base" on a car. If the front legs operated the same way as the do on a mammal, where the joint is behind the shoulder, then I think they would find the hooves spend most of the time touching the ground in front of the shoulder, which would add to the stability when running, galloping, etc.

Bunches of mammals DO have their front legs with knees (elbows?) facing forwards. Like cows, goats, horses, antelopes and so on. In fact pretty much any hooved/herbivore animal has legs that bend forwards. ...Except, uh, elephants. Exception to the rule, and all of that I guess! :)

Of course, elephants don't have hooves, so they're only a partial exception. Other non-hooved herbivores like rhinos or hippos do have forward-facing knees.

Not sure why most herbivores differ in this regard compared to predators like big cats, wolves and such, if there indeed is any survival benefit at all from either choice...

Duh! Got it partly wrong ... again. Thanks for correcting me. Yes, it does seem that horses, cattle, etc, do have their legs that way, and yet others like cats and dogs have them the other way around.
Still, I think having the front legs on that robot so they bend forwards would make it more stable than if they were the other way around.

What they have facing forward on the front is the carpus - our wrist. The elbows still point backwards. Equine and ruminants walk on their phalanges.

Quadruped predators like big cats, wolves, and bears have multiple uses for the distal forelimbs. For one thing, they have claws and use them as weapons. Quadruped herbivores pretty much use them only for locomotion, so the distal forelimbs (and hind) can be very lean. The light weight distal limbs allow more energy efficient movement, so the deer can sprint much longer distances than the predator, if not quite as fast. Elephants, I suppose are all about supporting the mass and don't have much need to run away in any case.

All of the animals you mentioned have knees that bend the same way. They bend the same way as ours.

Elephants, cows, cats, dogs- all have knees that bend the same way.

Yup, I was thinking the same thing. The only reason to go with legs over tracks or wheels is to handle harsh terrain. By the way the flesh and blood mule is excellent in harsh terrain, its why they were bred in the first place.

Both fictions come to mind with this. Of course one of the major challenges yet to be overcome is the power system. In most fictions the power system ends up being the size of a roll of quarters and will last for years if not tens of years.
I doubt we'll ever achieve that.
