K'nex Strandbeest

K\
A motor powered Strandbeest made from K'nex!

Strandbeests, which means "beach beasts," are a type of kinetic sculpture made by Theo Jansen. These sculptures are able to walk with only wind power. After designing the walkers with a special algorithm, he races them on the beach to measure their fitness and incorporates the best traits to modify improve the design. The designs grow more complex over time, and have artificial stomachs, obstacle detection and other features. This video should give you an overview.


Here is a video of my Strandbeest. It has terrible traction on concrete, and the motor is a bit underpowered.

what are the 3 black rods
Jan 3, 2011. 12:32 PMSenior Waffleman says:
the strengthened black rods are used to connect the to pairs of leg he used in the strandbeast, if you dont have any, use the grey/orange long knex rods

Such fascinating examples of kinetic art! Can they be ridden like a bicycle and steered? Could they hold my weight? GAH! I have to find out more! =P

The walking mechanism you are using is called a ''Clan Linkage''
Feb 4, 2010. 6:44 AMiprefermuffins says:
Actually, a Klann Linkage seems to be pretty different from the linkage used in Jansen's Strandbeests. Here is a comparison: http://www.mechanicalspider.com/comparison.html

Same as Oompa-Loompa. I am definitely making one of these. (I just need a motor first) I have thousands of pieces, but no motors. Very sad.

oompa loompa WAS smart, now he is just average.

I got my motors from roller coaster sets, they have lots of rods and a motor. Just make sure it isn't a plug in model if you are going for something mobile

Nov 23, 2008. 10:29 AMWoD5 says:
these are very real but there not alive they simpley have a bunch of simple sensors like tubes kenected to botles, to sence the water, and a BIOS (basic imput output) toproseses left and right or 1s and 0s. but i could understand your disbelief. there quite amazing machines.
Nov 25, 2008. 2:21 AMgrevious says:
wow they do seem very simple for there functions, ill have to look deeper into these...
Aug 21, 2008. 4:22 PMYour Average Guy says:
Srry for double comment, can I make one of these move with a wind up?
Aug 22, 2008. 8:54 AMYour Average Guy says:

Aug 24, 2008. 3:40 PMYour Average Guy says:
Ok thanks, yeah i just figured that out.
