    According to Einstein, these might be the weapons of the future:

    I was going to post something about the latest in robotic weapon design, but ran across this news article from 2007

    http://www.itweb.co.za/index.php?op...157&catid=96:defence-and-aerospace-technology

    Wow.

    There was a post before mine that vanished, now the context of my post is ruined.

    Yeah, and my joke. And I thought it was a good joke.

    I live in a world where I have to dance around liability concerns constantly. When I hear about a system like this going bezerk it makes my teeth curl. But it seems to be unavoidably true that robot weapons [the stuff of sci-fi, not that long ago] are quickly coming of age.

    When I was in high school, I gave a speech about how one day we could reach a point where war need not involve humans: When our robots defeat their robots, they will surrender as there is no hope of survival otherwise. There would be no hope of defeating an army of robots. More specifically perhaps, when technological defensive systems are defeated, some form of overwhelming force, perhaps nuclear, is the game ender. Resistance is futile. War in the conventional sense, a thing of the past. I still wonder sometimes if that day will come.

    Or is this already the state of affairs with China. Anti-satellite weapons have come of age. And how many cyber attacks does the NSA fend off every day?

    "The wars of the future will not be fought on the battlefield or at sea. They will be fought in space, or possibly on top of a very tall mountain. In either case, most of the actual fighting will be done by small robots. And as you go forth today remember always your duty is clear: To build and maintain those robots." - Simpsons.

    I have doubts, that on the ground, robots are all superior to humans.
    For example, one futuristic weapon is EMP, that destroys delicate electronics. And it is already under testing.
    Also there can be quite difficult environments on the surface, the robots have to be expensive. In future, i think, we will mostly have to deal with terrorism and urban warfare, and many cases, immediate human level decision making should be needed.

    Other futuristic weapons are lasers, rail or coilguns, particle cannons.

    Lasers are still weak, they can serve anti-missile purposes by blinding or overheating them. A railgun was quite powerful, but erodes quickly. I dont know any details of particle weapons.

    Pointing press and web pages are good weapons.

    Clearly at the moment they are not though robotic warfare is developing at a rapid pace.
    We can already do this with nuclear devices and whilst there has been extensive research into non-nuclear electromagnetic pulse (NNEMP) weapons none have ever been developed to the point where they can be usefully deployed. Either way however shielding from EMP has been around for decades, I'm given to understand your average off-the-shelf military equipment is shielded to a certain extent. If it began to be a problem e.g. if country's did start manufacturing useful NNEMPs then I'm sure shielding, redesign and tactics would be developed to compensate.
    Yesterday's high-tech is tomorrow's cracker toy. Regarding difficulty on the surface I recall reading an article a few years back on the advance in collaboration and swarm intelligence in robots. It detailed examples of a UGV that had to navigate accross a field full of ditches, mounds, bushes, fences etc. It did so by deploying a mini-UAV from it's roof that flew around and mapped the area, helping the UGV create a route.
    Both of those could be supplemented by robotics and infact already are;

    And in terms of fighting in buildings it's not that difficult to envision something like this supported by a team of drones like this? In terms of immediate decision making you can approach that by improving the software running it, including humans in the loop and mitigating the cost of mistakes. An example of the latter could be to fit the drones with non/less-lethal weapons in case they target innocents.
    Whilst there has been development in laser weaponry examples like the Boeing YAL-1 project show that the technology has a way to go yet until it's viable. Having said that there are various continuing projects such as the US navy FEL. Along similar lines railgun's are also under development for ships.

    Particle beams I also don't know much about other than the fact that there doesn't seem to be much development there.

    The video of quadrocopters was pretty impressive, just to shade it a bit, we dont know, the exact succes to fail ratio, and how much help did they got from their operators.

    But of course, with enough refinement and practice, they will be fine, especially for exploration purposes.


    About microwave weapons :

    http://www.globalsecurity.org/military/systems/munitions/hpm.htm

    "The problem with Faraday cages is that most vital equipment needs to be in contact with the outside world. This contact point can allow the electromagentic field to enter the cage, which ultimately renders the enclosure useless. There are ways to protect against these Faraday cage flaws, but the fact remains that this is a dangerous weakpoint."

    Future terrorists may easily convert their microwave owen into EMP weapons.

    drones are an interesting concept. NOW YOU CAN KILL PEOPLE WITH 20% LESS GUILT! BUY NOW!

    OFF : Well yeah, that is my main problem with robotic armies. I dont want that my sons die a "heroic" death, but they can still die in a bombing, because politicans start to believe war is a computer game.

    ON : images, videos

    About the last one, well i guess they cant contain waste heat for much time... but if they can contain it till an IR missile misses that is good.
    Of course there will be more advanced sensors.

    Well, politicians are probably already pretty dissociated from the actual killing. Drones allow your soldiers more emotional stamina so you don't go through them so quickly. PTSD is probably expensive to treat and give up a trained unit for.

    err... not to mention losing a unit to non-coward warfare.

    The real problem with drones is that they can be used against you and won't complain.

    True. As much as I'm a pacifist I acknowledge that conflict sometime's is inevitable. I'm hoping that future weapons technology (of which drones are an obvious part) will be sophisticated enough to massively reduce death tolls. Aside from increasingly precise bombs/missiles that have allowed us to move on from 1940s era carpet bombing I'm hoping that in the future taking out a tyrant or terrorist group is as easy as sending a MAV that can fly into their base and remove just them. I'm also hoping that increasing developments in non-lethal weapons and UGVs along with a shift in public and political opinion will see conflicts where most combatants are temporarily incapacitated rather than killed. If you have a drone in a conflict situation it's "death" means less than a real human and it could be more resistant to damage, this means that there is less importance in being able to quickly kill your opponent. Public and political opinion may be forced to change if we continue to see reports of drones that target schools and innocents. Of course on top of that we have what Ivan mentions above about drone-on-drone conflict and how it might change the nature of warfare.

    I use the word hope a lot there because in no way do I make this is a prediction, even though I think the individual developments are likely I'm not so sure of my optimistic outcome.
