BigDog robot starts throwing bricks

Boston Dynamics BigDog

The BigDog all terrain robot from Boston Dynamics was already the stuff of nightmares, but has just got even scarier thanks to a great big mechanical arm on the front for slinging masonry.

The DARPA-funded walking military robot is undergoing tests to develop techniques that utilise the power from its legs and torso when performing arm movements, much like a discus thrower (or a hoddie?).

BigDog doesn't just possess the rockstar ability to throw things, it can also run at 4mph, carry a 150kg load, scale 35 degree inclines and walk across rubble, snow and mud.

As with most large, four-legged beasts the advice is "don't stand behind it" – because there's nothing like getting a brick in the face to put a dent in your day.
