K'nex Strandbeest

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.

This is cool, this is the next thing I was going to attempt after I took apart my K'nex clock.
AWESOME!

what are the 3 black rods
Senior Waffleman in reply to Franky14Jan 3, 2011. 12:32 PM
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

You are insanely smart, and this thing is truly "beest"!

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

(Factoid)
The walking mechanism you are using is called a ''Clan Linkage''
iprefermuffins in reply to MoonlightWolfFeb 4, 2010. 6:44 AM
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

Miles Tails Prower in reply to riku1Jul 25, 2009. 12:51 PM
It's 6 volt with 4 AA batteries. I have one. Double as powerful and has two speeds.
riku1 says: May 27, 2009. 2:49 PM

The Great Knex Warrior says: Apr 9, 2009. 1:05 PM
you have made the crank move the wrong way to the legs.
smilee says: Mar 22, 2009. 9:47 AM

grevious says: Oct 17, 2008. 7:49 AM
ummm... i looked at the video and now im confused, ar these things actually real...?
crestind (author) in reply to greviousOct 17, 2008. 9:04 AM
What do you mean?
grevious in reply to crestindOct 17, 2008. 10:56 PM
is a strandbeast a real thing? or is not?
WoD5 in reply to greviousNov 23, 2008. 10:29 AM
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.
grevious in reply to WoD5Nov 25, 2008. 2:21 AM
wow they do seem very simple for there functions, ill have to look deeper into these...
Your Average Guy says: Aug 21, 2008. 4:22 PM
Srry for double comment, can I make one of these move with a wind up?
crestind (author) in reply to Your Average GuyAug 21, 2008. 6:41 PM
It won't work. They're nowhere near powerful enough.
Your Average Guy in reply to crestindAug 22, 2008. 8:54 AM
what about with three wind up motors?
crestind (author) in reply to Your Average GuyAug 22, 2008. 8:56 AM
They'll start off strong and lose power very quickly, so you'll probably only get one revolution or so. It needs continuous power.
Your Average Guy in reply to crestindAug 24, 2008. 3:40 PM
Ok thanks, yeah i just figured that out.
Oompa-Loompa says: Aug 6, 2008. 8:24 PM
I favorited this so I know where to find it when I take apart my sniper rifle. Really cool.
