BBC News reports that “The US army says it has mothballed plans to deploy a robot developed in conjunction with Google because it is ‘too loud.'”  

“The Legged Squad Support System – referred to by some as “the big dog” – is capable of carrying 400lbs (181.4kg) of equipment over rugged terrain.”  

“But the US Marines now say its petrol-powered engine is too noisy for them to use in battle.”
