Introducing the 20 legged 3D Printed Strandbeest : Animaris Geneticus Ondularis

20 legged 3D printed Strandbeest

Theo Jansen’s 3D printed Strandbeest continues to evolve with an even more elaborate walking mechanism and a centipede-like walking motion. The latest evolution called ‘Animaris Geneticus Ondularis‘ walks on twenty separate legs that move in a wave sequence. This new configuration results in a fluent walking motion, different from its twelve legged predecessors. It incorporates 122 moving parts, showcasing the complexity of mechanisms possible with 3D printed fabrication. It is also slightly larger than its predecessors. The operating principle of ‘Animaris Geneticus Ondularis’ is based on one of Theo Jansen’s original beach walkers, the ‘Animaris Ondula’.

    Wow, that motion is really smooth! It’s beautiful to watch. :-)
    Will it work with different materials or are there issues with the balance?
    Really amazing work!

    good mornin, is the strandbeest for sale?what is the price.
    i have a missing king for my chess set, can you make a a copy? if yes, what should i do?
    trhanks, milan

    Amazing work!!! Congrats!!! which printer did you use?

    Pity the one I bought from Shapeways only moves if it is kicked.

    Print job has too many rough edges in the joints and prohibits the fluid motion prestented here. Sales pitch better than end product by far!

    That is remarkable, Theo. Just like the big one on the beach. I don’t know much about 3D printing kinetic art, but I can grease up John Deere combine.,

    Like a robotic version of the Rockettes.

    If we use this as the tire of the cars, we wouldn’t need to asphalt all the roads, we could actually have green soft land instead of all the asphalt roads.
    all we need to get the earth back is to invent a better wheel which awesome Theo Jansen’s 3D printed Strandbeest to me seams to work
    i suggest you should meet some people who can get help from your design and make this happen together
    good luck
    thank you

    How the heck does that work…?
