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

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.

    At any rate, no power steering is a good thing, in my humble opinion. If you have power steering and it breaks then it is actually more difficult to steer than a vehicle designed without it. It's an unnecessary point of failure. The HMMWV has power steering and it had some issues but they've ironed them out to the best of my knowledge. I'd have preferred that it be designed without it. If I recall correctly, it has backup lines and the steering ratio is not so high that it makes it too difficult should the pump fail. However, it has been a lot of years since then.

    The lighting on the HMMWV wasn't the greatest either, now that I think about it. It wasn't terrible and we never brought extra bulbs with us. When they were covered with the blackout slits it was rather tough but other than that it was okay, I guess. It's not like they had high intensity discharge lamps like the BMWs or anything but they weren't too bad. You're also seated pretty high and the lights are fairly high off the ground so I guess I can't really complain.
