“Since about ten years he is occupied with the making of a new nature. Not pollen or seeds but plastic yellow tubes are used as the basic material of this new nature. He makes skeletons which are able to walk on the wind. Eventually he wants to put these animals out in herds on the beaches, so they will live their own lives.” — Theo Jansen’s bio

On the left you see a polypedal walking contraption (designed with a genetic algorithm), and on the right, a pneumatic hammer driving a stake into the ground with multiples blows (when it senses the high winds of a storm).

He showed how they harvest energy from the wind with sails and propellers and store it in compressed air bottles, which can then be used for motion or logic. He also demonstrated a pneumatic binary adder.

The creatures roam the Dutch beaches, retreating from the ocean with water sensors and avoiding dry sand. Here are some videos of the strandbeesties in action.

  1. wow. so obvious but so unprecedented. i love when people pull stuff like this off. plus: less pollution than burning man. cool!

  2. Wow!
    I checked the videos and THEY LOOK ALIVE!
    So cute. I admire this man’s passion!

  3. those beasties aren’t stranded, for certain! absolutely incredible, a total joy to watch. these are like a sedate, refined and joyously autonomous alternative to Mark Pauline’s insane Survival Research Laboratories project.

  4. I must agree with csharp_gal – the videos are definitely worth a look. The last one looks so natural, I had no idea anyone had produced anything mechanical which was able to ‘walk’ so gracefully. Inspiring stuff! And to think they evolved!

    Steve: Did he discuss anything about his GA – was the selection automatic or observer based?

  5. Quite a smart fellow, he figured out how to get inanimate objects to reproduce.

  6. Robot love.

    biotron: SRL should invite the peaceful strandbeests over for a little house party….

    gail, csharp, et. al: yes, they are much more elegant than robo-giraffe

    And in Theo’s work, I noticed a similar wave propagation as in nature’s segmented polypedal beasts:
    Polypedal Grasp

    mrmanc: good question! Here is some more info: "Jansen built a genetic algorithm to design a leg that would walk in a straight line – his leg has 11 lengths of tube attached together, and getting the lengths of the 11 pieces of tube right is a hugely complex mathematical challenge. Jansen created >1000 virtual legs with random parameters on a computer, “cross-bred” the 100 that were most fit – walked in a straight line – and then built complex beasts around these legs." (from Our Windpowered Robot Overlords)

    It reminded me of the design process for what I call the Chariot of Wire:
    Robosapiens

    He designed the cams through trial and error to mimic his own gait. Getting it to walk backward was a lot easier, and was the first step, so to speak, since the designer could consciously perceive his own subcomponents of motion while doing a strange act. Walking forward is so far down the neural subsumption stack so as to be difficult to decompose.

  7. Thanks for the discovery Steve : )

    I decided to do the relay with a little photo :

    By the way, for all of you,some TED Talks are now available here :

  8. Okay, I suppose then that the fitness function was calculated automatically using some 3D simulations unless he did a hell of a lot of intermediate building 🙂 I much prefer to see GA’s used where the result is less contrived / Dawkinesque. Superb work though.

  9. thanks again Steve : these are so wonderful that I ordered the DVD from his website on late Thursday evening, received it early Saturday morning and watched it almost immediately – fast service!

    mrmanc – judging by the amount of material shown on the DVD, it seems he also did a hell of a lot of intermediate building anyway, regardless of his computer-aided simulations…! 🙂

    i love the fact that some beesties scoop up some sand, walk to a point, stop to deposit the load, and change direction… repeatedly… and then it is claimed that the future problems of a low-lying country like Holland might be negated by such wind-powered automata gradually redistributing sand from near the tideline further up the beach as a defensive levée – hilarious!

    i watched the whole presentation wondering why he doesn’t make miniature versions that could also be wind powered, or wind-up, or whatever – for kids (and biotrons / other interested parties) to play with?! he probably doesn’t have enough time in the day…. and making them a commercial product is far removed from the spirit of what he is doing… but still… it could be a cracking executive toy for a couped-up office worker or bored librarian, having a miniature polypedal worksurfacebeest to "interact" with and set off on grand voyages across the desk etc etc

    i also wonder : where does the law stand in relation to patents when using GAs to inform designs such as this?

    incidentally, his old light-sensitive spray-gun (which scans line-by-line along a wall and reproduces what it is exposed to) is also fantastic.

  10. Hi, please add your best Strandbeest photos to the new Strandbeest Group pool
    We’re trying to build a map of the evolution and global migration of these crazy creatures!
