A hexapod with servo joints. This design is quite big and needs strong servos but looks really cool ^^.

I used 20 HD-2213MG Servos (http://www.servodatabase.com/servo/power-hd/hd-2213mg) . If you use other servos you need to modify the embeddings for the servos and servo horns. You may make the upper and lower legs shorter to get shorter leverage.

Finally the parts get assembled with M2 thread rod and nuts.
