51. Quadrupedal human walk


video

Continuing on the quadrupedal study I decided to get down on all fours and try to see how our four legged cousins walk. 

This is very much a mammalian walk. I used a human figure and applied the dynamics of the four-legged locomotion from yesterday. Following that I've adjusted the position based on my own experience in order to understand the musculature and skeletal structure which powers such walk. In order to keep the momentum tip-toe walking is necessary and that accounts for the development of paws, hives etc. Similar is true with frontal limbs as an additional point of articulation allows for higher precision during the step. It is a kind of devolution to retrace the walking steps backwards and work on it from the understanding of a humanoid. Most of the back movement is in the waves of the spine and lower abdominal contraction in order to bring the hind legs closer. this accounts for strong and powerful hind legs in most quadrupeds. (there is some difference with reptilian sprawl but that will come later).
