The Sea Beast - a 12 legged walker

Featured
Picture of The Sea Beast - a 12 legged walker
This beast has 12 legs and is driven by a motor in the center. The legs walk the same as those from the "Strandbeest", made by the famous kinetic sculptor Theo Jansen.




Piece list for one pair of legs:
Rods
10 white
8 green
1 Blue

Connectors
18 black hinge halves (These are a must!)
10 gray 1-way
10 gray 2-way
8 tan

2 blue spacers


note: In my own model I used black snap-on caps instead of tan connectors, you could use them as well if you have them.
note 2: This uses a lot of black hinge parts, you can buy these at knexusergroup if you live anywhere but in the US.

Enjoy!

Step 1: Making the legs

This step is for making one pair of legs. You will have to make this part 6 times.


So the legs are pretty tricky, lets start with making all the loose parts for one leg first.

Once you have made these you can put them together like shown in the next pictures.

Alright, then you have to make another one, and connect them together with a blue rod, two spacers and two gray connectors, and your'e done!

Step 2: The axle

Alright, this part that goes between the pairs of legs. Simple.

You could also use a gray connector instead of the black hinge I've used.

Step 4: The Frame - Part Two

The motor can be any motor, but preferably this type (not the ones with a red batterypack). As for the axle, its a yellow size rod. Make sure to put the connectors at a 90degree angle!

Also at one side the green rod should pop out a bit, see picture 4.

Step 5: Connecting the legs

Now we have to lace 3 leg pairs together on two gray rods. Just follow the pictures, but make sure you don't miss any blue spacers.

In the fourth picture you have to shove the axle part onto the blue rod from the legs.

Make two of these

Step 6: The Head

 Right time to put the head together! :D

I made it 5 stars! :)
WOrks well (I haven't built it yet) but Just saying this thing would be a nice back massager! I cant see what are the peices on the legs that are on the white rods in the middle of the first picture?

I think you mean > these <
oh I have the hinges but not the caps too bad...
Kairah (author)  aleceatsfood3 years ago
You could use tan connectors instead and make only 4 pair of legs.
Just keep enough distance between the legs.
how many hinges does 1 leg use?
Kairah (author)  aleceatsfood3 years ago
One leg uses 9 hinges, as you can see in the first picture :P
oh i guess i was too lazy to look. And I only have like 4 hinges :P
Very nice and compact! 5* But I've got a question, does it matter how long the axle is??? You used a yellow rod, can it also be a red rod (I'll have to 'cause my motor is pretty wide).
Kairah (author)  michiel1234567893 years ago
Cheers! If you are going to use a red rod, you will need to make some more distance between the first pair of legs and the motor. Otherwise the axle will stick between the legs and it cant walk! :)
Ok thanx!

 All i can say is this looks awesome! I built the strand beest done by crestind, but this looks a lot sturdier. I can't wait to build it!

 I'm amazing.Just kidding. Ok so I found away that you can not use all the black hinges. Look at the picture!

p.s. Sorry for the bad quality picture, i was using my web cam.

If you put the black clip on in the other direction it turns slightly better.

 correct! it doesn't work quiet as well but its better than not getting to build it.
Kairah (author)  sprout_less4 years ago
Do you mean like this? It fits, but doesn't turn very well unfortunately.

Just pure plain awesomeness, knex style. Great work, 5 stars!

OH MY GOD!

That thing is beast!

I'd build it, but I don't have that motor. Oh well.

5* and faved!
The original Strandbeest were wind-powered...
A breakthrough in technology!

XD

...
Think of it as a challenge - you have no motor, but you do have enough K'NEX to build the mechanism.

Add sails.
Lol, it'd need to be pretty windy for that to work...

Blackpool beach... perfect...
Have a google - the originals were huge.
Kairah (author)  Hiyadudez4 years ago
 What motor's do you have then?
The big silver trekker motor, the plug-in one, 2 battery pack ones and a pull-back (lol.)
