I want to copy from Theo Jansen's beests.

Whoever want can try to make.



I see the triangles are stable and the squares are kinetic.






I have no idea of cranks.
The aluminum wire I made does't make a smooth movement.


At least, the 6 legs necessary. So I am supposed to make more 2 legs.
If less than 6, it will not keep horizontally in walking.
