Of Ants and Robots

Posted by Zonk on from the both-pretty-much-work-the-same dept.

conJunk writes "The BBC has an interesting story about Ants and their leaderless collective behavior. It goes on to describe these cool little robots called U-bots. They have a super-simple instruction set and if you let them loose in a room full of frisbees it looks, to the casual observer, like intelligent and guided work." From the article: "Being small is going to be a problem. So how can you get a whole bunch of dumb small things doing something smart?"

    ... are also far more intelligent than the average human being realizes.

    There's a good article on their learning process here.

  2. Autonomous Small Robot Behavior by KingOfTheNerds · · Score: 4, Informative

    I work with small autonomous robots who accomplish basic tasks by working together. As a computer engineer I handle both the hardare and software, so I understand how they would appear 'smart' and 'guilded'. The trick is all in the programming, so that they work together to complete the task without proper communication. As long as they can react well enough to their surroundings (by reacting to eachother) and know what task they are to accomplish, it will look like they are working together as a guilded collective when really they're independant and autonomous.

    See Douglas Hofstadter's seminal book for discussion of ant colonies, AI, emergent behaviour, etc. http://www.amazon.com/exec/obidos/tg/detail/-/0465 026567/qid=1110055317/sr=8-1/ref=sr_8_xs_ap_i1_xgl 14/103-1941748-8383854?v=glance&s=books&n=507846

  4. Re:Good example of emergent behavior by MyIS · · Score: 3, Informative
    The use of word "emergent" here means that it "emerges" from very simple building blocks (that's just in case someone thinks it's for emergencies).

    Anywho, any examples of what you provided only reinforce the parent statement. Each ant knows very simple things it can do. When all of them do those things, they do so without a central commanding point. When thousands of such simple things are done in unison, a very complex behaviour emerges, such as building fortifications or harvesting food. The fact that there is no central ant generalissimus to point them around means that it is an emergent behaviour.

    This area of AI is a fascinating one. Games like Grand Theft Auto can exhibit very basic examples of it.

    I'm pretty certain I saw this program on (very) late night BBC Open University TV about two years ago. It got me very interested in this sort of behaviour, but the more research I did into insect behaviour, the more apparant it became that some kind of simple pheremone system is actually used in nature to control things. Many swarm intelligence projects now use "Pheromone robotics" to mimic nature that little more closely. http://en.wikipedia.org/wiki/Swarm_Intelligence
