THE STORY

After seeing Theo Jansen mechanism on YouTube I wanted to do my own walking machine. In fact it was an old dream that dates back to the time I was 13 years old when I saw the Empire Strikes Back. That's why I wanted to do a four legs walking machine with a synchronisation mechanism for the legs.

OTHER 4 LEGS WALKING MACHINES

LAUFMASCHINE - A German walker using the same leg synchronisation mechanism.
................................................................................................................................... 木犬 MOKKEN ( Wooden Dog ) - A Japanese walker made by Mr. Murayama Yuki.
Mr Yuki Murayama, student of Tokyo institute of technology sent me some pictures and movies fom his walker "Mokken". It has one motor, it uses Geneva stop mechanism and Chebyshev linkage. click for an animated version
