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
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.
