Watch this first!!!:

Question

What is the sequence of leg movements for one complete step? Use the terms BL, BR, FL, and FR for the back-left, back-right, front-left and front-right legs and Explain how this sequence of movements manages to balance BigDog’s body weight.

Firstly, when BigDog was kicked on the video, the FL leg moves to balance the weight on the side that it was kicked, which was on the right side, this is then followed by the BR leg. Then, the alternate legs, FR and BL will reach out and balance the weight again. Afterwards, both the FL and BR legs will reach out one more time to change the weight of the whole body and thus stabilizing the whole body with FR and BL legs following it.

Here’s a story board for the BigDog animation(in a way T-T) :

Finally my animation of BigDog:

And here’s a improved version of it:

For this whole exercise, it is quite difficult to know when it should be rotating on the right or left as well as the when the legs should move. But I suppose that is to show how weights are balanced when someone was kicked.
