Robot Mule Put Out To Pasture By Marine Corps (nbcnews.com) 153

Posted by samzenpus from the quiet-down-now dept.
An anonymous reader sends word that the Marines have decided that Boston Dynamics' robotic pack mules are too noisy to use. NBC reports: The massive robotic mule developed by Alphabet-owned Boston Dynamics won't see combat with U.S. Marines. LS3 (Legged Squad Support Systems) was meant to carry cargo for weary soldiers in the field. Funded by the Defense Advanced Research Projects Agency, or DARPA, the robot was capable of walking with 400 pounds of equipment on its back. LS3 could run for 24 hours straight on a 20-mile mission across rough terrain. No controller was needed; it took visual and verbal cues from soldiers to find its way. So why doesn't the Marine Corps want to use it? The robot's gas-powered engine isn't exactly the stealthiest piece of technology.

        Horses require a lot of care and feeding. You can keep the mechanical mules in a warehouse until needed, parachute them in, then let them sit in a pile for a few weeks until ready to use them, then just gas them up and go, any time day or night.

      On top of that considering a mule can be frightened by explosions and other combat conditions, and you need to potentially worry about food/water/shelter versus cramming a robo-mule into a crate at a warehouse when you're done with it.

      Well, the US Army used mules regularly until 1957, and they're still used occasionally in special operations. The Marine Corps still conducts training in handling pack animals at it's mountain warfare training center.

      Pack animals do make sense in limited situations, and mules are superior to horses in those situations because they require less and lower quality feed.

          While that's a cool fact, do you have any data to suggest that many horses can do this (and that mules can't)? I'm going to go out on a limb and guess that your example is an exception rather than the rule.

          • While mules are well known to be more sure footed, more resilient to heat, and less prone to disease and injury they are also known to be less reliable under fire. That horses have more "bravery", allowing them to not only be used as pack animals but reliable partners in battle even in the age of gunpowder. While this particular horse's exploits are exemplary, as are the actions of many recognized heroes, it is in the nature of horses that such examples arise.
