LS3 - Legged Squad Support System

  • Published on Sep 9, 2012
  • The Legged Squad Support System (LS3) is a rough-terrain robot developed by Boston Dynamics with funding from DARPA and the US Marine Corps. It is designed to carry 400 lbs of payload and travel 20 miles without refueling. LS3 has sensors that let it follow a human leader while avoiding obstacles in the terrain. For more information visit

    For such a heavy machine, it's surprisingly nimble. Especially on the dirt road.

    give it 5 years.... The march of time is particularly kind to technology and the capabilities of this idea will expand exponentially. might see these as mobile ammo carriers and emergency replenishment for particularly hot areas. Imagine if they had the top speed of say a horse.

      "By late 2015, the Marines had put the LS3 into storage because of limitations with the robot including loud noise, challenges in repairing it if it breaks, and how to integrate it into a traditional Marine patrol. Since 2010, development had cost $42 million total. No future experiments or upgrades are planned, and it would take a new contract and interest from Marine Corps top brass to resurrect the program. Although creation of the LS3 did not result in accepting it into service, it did provide important insights about autonomous technology." - Wikipedia
      It only took 3.. and the march of time wasn't particularly kind to this technology :P

    well, this has come far, last i saw it on tv somewhere some time ago, it was still tethered to some crane for power and i don't think it could "see". i remember thinking how awesome and lifelike it acts if you give it a good hard push (like cow tipping) and it would scramble to keep balance!

    @capslockbandit yea i thought about that and it does make sense. this combo will never see combat but if u took each new tech and used them in other ways like APC with that navigation system it would be useful in rescue in super hostile territory or recon/ automated security and a forward outpost or encampment.

  • ColJochen
    ColJochen 8 years ago

    These things will definitely be involved in logistics and supply. Delivering ammunition, shells,fuel,food etc to troop positions if air-drops are risky. I can also see these things with weapons systems mounted on them (like the systems on AFV's and MBT's) for fire support. Or possibly a scaled up version of this one with artillery/mortars mounted on it.

    They have already tested it with a corvette engine on it's back on ice!!! And it steadied itself!!! It's supposed to be used in any kind of war situation to take medi packs to soldiers that are hurt or even if they have to...carry soldiers out of bad situations. This is supposed to take the place of a soldier so less get put in harm's way.

    Try to imagine this thing in 25 years. If development continues, it'll gradually become quicker, more silent and cheaper. The first airplanes used in a war weren't as quick and stealthy as the ones they use now. The first guns weren't as accurate or powerful as the ones they use now, etc.

  • bartflannigan

    I will concede that there are some benefits and very specific applications this would work for, and i am intrigued by the proof of concept. The only application i can see it being beneficial for is supply when an air lift isn't possible and vehicles cant maneuver in the area. Adding armor only makes it heavier, consume more fuel/energy etc... what about loosing a leg, a heavy machine gun will slice through all light armor and all the tastey tech bits inside.
