The ‘mule-bot’ walks again

By Jennifer Rizzo

The military's robotic beast of burden went out this week for another stroll, demonstrating advancements in the way it moves through real-world environments.

The LS3, first revealed in February, is designed to carry heavy loads for troops in the field - up to 400 pounds worth of equipment.

In the footage released by the Defense Department's research and development arm, two of the mule-like robots can be seen navigating hilly terrain with relative ease, sidestepping rocks and getting up from a sitting position.

The new and improved version of the LS3 is roughly 10 times quieter than what was seen earlier this year and has the ability to "easily transition" between speeds ranging from 1 to 7 mph, "showing the versatility needed to accompany dismounted units in various terrains," said Army Lt. Col. Joe Hitt, a program manager for the Defense Advanced Research Projects Agency (DARPA).

The robot, which is being developed to have the ability to recognize basic voice commands, such as "stop," "come here," "sit," or "go over there," is able to follow a human leader and track members of a squad in forested terrain and high brush, according to DARPA.

"The goal of the LS3 program is to demonstrate that a legged robot can unburden dismounted squad members by carrying their gear, autonomously following them through rugged terrain, and interpreting verbal and visual commands," said Hitt. "The vision for LS3 is to combine the capabilities of a pack mule with the intelligence of a trained animal."

The agency had previously designed a similar four-legged robot called BigDog, which demonstrated to the research group that a "legged" design would be able to handle harsh terrain.

"BigDog was about mobility. Can we have a four-legged system navigate terrain the way soldiers navigate," Hitt said earlier this year. "We took BigDog's legs and put them on a platform three times the size and gave it eyes so that it could see its terrain."

The LS3 is smarter and stronger than its predecessor, which was able to carry only 100 pounds.

Onboard sensors allow LS3 to perceive obstacles in its environment, differentiating between a rock and a tree for example, and give the robot the capability to plan a different route.

Testing on the robot is planned to continue for two years, at which point the LS3 will be embedded with a Marine squad.

    Critical of DARPA, on the contrary. They have produced many advances that have made a positive difference in our lives. People want to know more about that, go to their website. This is about taking the negative and seeing the positive. As for the people mentioning going back to pack mules and horses. Right, I can see what will happen when the first IED or RPG kills one! I hate to be the one to justify this to the Human Society of America when it could have been a machine.

    OBSERVATION: Nicely done – little noisy – let's the enemy know you're coming. Seems like an easy target that could be taken out with one shot! Seems like a misapplication for military service and our tax dollars. Looking for budget cuts?

      It might be able to be taken out quickly but it would allow for soldiers to be caring less equipment in the initial important seconds of the engagment. This would allow them to move faster and be more agile in combat. Also, they would be less tired from not having to carry 50 lbs rucks up the side of a mountain. All things that would save soldiers lives and let them be more effective in combat.

        Gee – I wonder how many miles it gets to a gallon – plus – who's caring the gas can?
        What happens if the robotic pack mule breaks down – is their a field mule tech?
        I admit it looks really cool – but the logistics of operation and deployment robotic pack mule will probably kill it in the end.
        Must be nice to have easy access to taxpayer dollars for this kind of half-baked ideas which are not thougt thru to practical use. I wonder what would happen in the real world if a company for profit would fund this kind of research to sell in the marketplace at a reasonable cost – where benefits and price cross each other making it feasibe? Just a thought. This kind of crap is right out of the movie "Terminator and SkyNet" – what a total waste of resources and national treasure – when this kind of money expenditure could be spend on improving life on the planet. We can do better then this!!!

        OBSERVATION: OK – so DARPA is funded with our tax dollars – they develop an idea to functional concept that works – then a too-big-to-fail corporation takes the researchs proof of concept and makes a profit. Show me how these tax dollars spent are paid back to the people as viable products? Looks like this military-industrial complex has gone wild and needs to be reigned in. It seems like if its done in the name of defense and killing people – money flows. But if its for sustaining and protecting life to create a better quality of life – to hell with it. It does not make sense – it's all insanity!

    It's not the technology that offends people, its about the militarization of it. Granted, DARPA is part of the military system, so it is what it is. On a positive note, if this comes to fruition, it will eventually have civilian applications.

    To all the folks claiming some variation of "this is a waste of money/time/resources," please remember that MOST if not ALL of this kind of technology and research ends up in the civilian markets as new, better, safer, more reliable products and services, more discoveries, and better technologies.

    In a few years this mule-bot technology might enable a person in a wheelchair to walk, 24/7 search and rescues, safer IED checks, bomb disposals, or boarder patrols.

      Because Mules are difficult to pack up and store, are somewhat unpredictable and can't be easily transported in a helicopter. Also mules have been evolving too slowly for our tastes. This "mule" was non-functional five years ago, is getting close to match a mule's abilities by the end of the decade and one decade from now it will beat them in every conceivable aspect. It is a research project and won't be ready for prime time for a few years, but when it is, no one will be asking why not use real mules instead, the advantages of a robotic one will be obvious.

    My god... are you people completely uneducated or mostly uneducated? I swear, if some of you people had your way, we'd be barely at wild west level of technology. Screw innovation unless it can give me an immediate use. So all you people whining about how loud it is for one thing... are you so dumb that you think this is the finished product? Uh no. And as for mules? Maybe the military would rather, in the freaking long run of course, have a mule that they can 100% control and not have to train, stable, feed, clean up after, etc.

    I just thank God everyday that that the people with the actual brains in their heads are working towards innovation and the useless members of society that just sit back and whine about it, putting no effort towards DOING anything about anything are the ones commenting on news posts.

    If it follows voice commands and is intended for military use... Please tell me they had the forethought to have it recognize only the voices of the soldiers it's working for... The whole it gets shot it's useless thing.. This is a prototype, not the finished product. I'd guess they're working on surviveability for it as well. It'd also be nice if it could use that big metal body in a combat situation. For example if a soldier is wounded and yelling for a medic etc, have it programmed to block the enemy's line of sight to the soldier, and possibly give it a grabber arm so it can drag the soldier to safety or load them into a bullet resistant compartment to carry them to an aid station. This could have a lot more useful applications then just carrying soldiers gear. It could replace the combat medic's role of exposing themselves to enemy fire to retrieve wounded, or be loaded with explosives and sent to take out hard targets as well.

      You ask why not use real mules, then talk about noise (mules are noisy) and complain bullets could stop it (mules are not bulletproof). What if it is disabled, you ask? The soldiers are no worse off than if they had never had it.

      This is a DARPA project. It is supposed to be relatively low-cost, risky and innovative with potential for long-term payoff. That is what DARPA does.

    Think about this though. Several times larger. Powered by a nuclear submarine-type generator. Potentially manned by multiple gun turrets and/or soldiers. A tiny fraction of taxpayer money went into this project in comparison, say, to how much gas was spent in one day by military service vehicles in the Middle East. If the government really pumped some taxpayer money into this we would have a terrifying war machine.

      It is clear that you don't know much about nuclear reactors. FYI, nuclear reactors require a constant source of cooling water in order to keep things stable. In order to cool the cooling water you need a heat exchanger. Submarines use sea water to accomplish this (not directly, because of safety issues but you get the point). I wouldn't want an air-cooled nuclear reactor walking around anywhere. It would not end well.

    Thank the Lord that the USA is the one creating this stuff (that we know of). Everyone should be aware that the exponential growth in technology will inevitably lead us to a cyberdyne systems (Terminator) type robot world. We the people, whose taxes are paying for this stuff and who ultimately will be living with these machine, need to know that there is a macro off switch and that it is in responsible hands. Mr. President and Members of Congress, “Please show how the off switch works”.

    Also, let's not be blind to red herrings such as the DARPA explanation that this is “designed to carry heavy loads for troops in the field". No doubt it can do that but fitted with night vision, AI, GPS, satellite feeds, a few 50 Cals, cannon and rockets (400 pds worth) this thing doesn't need a human soldier and can go virtually anywhere.
