Your comment is right, but it seems BD are still developing their robots to be more practical, and may eventually have something they could sell for use in the field. BD have battery-powered robots much quieter than the gas-powered Big Dog: Handle (https://www.bostondynamics.com/handle https://www.bostondynamics.com/handle), Spot (https://www.bostondynamics.com/spot https://www.bostondynamics.com/spot), Atlas (https://www.bostondynamics.com/atlas https://www.bostondynamics.com/atlas) Spot was mentioned in the article you linked to as being quieter but able to carry less weight and less autonomous than Big Dog. The Marines are resuming limited testing with a version of Spot upgraded for greater autonomy in 2018: http://www.military.com/daily-news/2017/04/05/spots-back-marines-resume-testing-with-four-legged-robot.html http://www.military.com/daily-news/2017/04/05/spots-back-mar...
