The Most Advanced Quadruped Robot on Earth
BigDog is the alpha male of the Boston Dynamics family of robots. It is a quadruped robot that walks, runs, and climbs on rough terrain and carries heavy loads. BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog’s legs are articulated like an animal’s, and have compliant elements that absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule, measuring 1 meter long, 0.7 meters tall and 75 kg weight.

BigDog has an on-board computer that controls locomotion, servos the legs and handles a wide variety of sensors. BigDog’s control system manages the dynamics of its behavior to keep it balanced, steer, navigate, and regulate energetics as conditions vary. Sensors for locomotion include joint position, joint force, ground contact, ground load, a laser gyroscope, and a stereo vision system. Other sensors focus on the internal state of BigDog, monitoring the hydraulic pressure, oil temperature, engine temperature, rpm, battery charge and others.

So far, BigDog has trotted at 3.3 mph, climbed a 35 degree slope and carried a 120 lb load.

BigDog is being developed by Boston Dynamics with help from Foster Miller, the Jet Propulsion Laboratory, and the Harvard University Concord Field Station.Development is funded by the DARPA Defense Sciences Office.

fuck me , horror

FIGHTER 177 says:

Does that need to make that fucking racket

TheGreatUtopiaCat says:

Finally, they have the sense to use a gasoline motor on one of these robots. Nothing lamer than a cool ass robot that needs 10 hours for a 1 hour charge

too much noise….sounds like a big fly

Put a saddle on it and charge people to ride it!

"Brand new" in 2015 hahahaha I love how they keep carrying this thing out every couple of years and saying the technology is brand new. They just did it again.

The Vengeful Engineer says:

Crappy piece of shit.

Judiska Ekonomen says:

I personaly hates this robot. Of all the robots there is, this is by far the most creepy of them all.

Pieter Ravensburg says:

iff the army is gonna use this at least the enemy will hear it coming 2 miles away lol

VoceCorale says:

Creepiest thing I've ever seen (or heard).

Juzek Pyk says:

rewelacja, po prostu majstersztyk :):)

Metal Gear !!!!

Ujuani68 says:

So..are you considering divorce? ;-D Sitting thru the Holidays with a like that can break even the toughest man..!

Даниил Величко says:

Это штука выглядит пугающе. Скоро роботы собаки захватят землю

wannacboi says:

Yeah, why are we using chain saw motors to power these things? Can't they build an electric servo motor that doesn't make as much noise?

fook yoo says:

like two guys carrying a desk… the guy in from has to keep from falling over backwards

Dutchy1965 says:

Looks a lot like my Mother In Law !

Wifi Thief says:

Car with human legs

KuWaiTi SuMeRi says:

are you gay ?


So Ten says:

fuck you
that enough?

KuWaiTi SuMeRi says:

type in english fucking paroski

KuWaiTi SuMeRi says:

fuck you philipino

Kay Nine says:

why don't people ride on it?

Ilya Aganichev says:

It's too noisy for autonomous unit, but soft is good. look the reaction for the pushing!! IMHO gas turbine engine have to be a power supply.

4XLED says:

The people are not developing an engine silencer :)) you prikol. Such trivial things will be made much later.
