Big Dog Exercise

iii)   Look at BigDog_kick_slow_motion.mov. Draw a storyboard of BigDog stabilising itself after being kicked.

You should draw the key poses. You don’t need to draw well – but you must show the leg positions and the body rotations around the X, Y and Z axes for each key pose.

1) When kicked, Big Dog's CG will shift off to the opposite direction of which it's being kicked. If Big Dog doesn't respond to this shift of CG, it will fall. To avoid the CG from going out of the SA, Big dog has to move its legs. Firstly, it moved out its FL to expand its SA. It crosses over its back legs while the front legs spread out. Next, to counter the spread of the front legs, the back legs have to follow suit while the back legs close up. This process repeats until the CG is not shifting anymore

2) By moving its legs, Big Dog is able to shift its SA accordingly to follow it's shifting CG. By doing that, Big Dog won't topple over because the CG didn't went out of the SA.

3)

Just like how it is described on Qn 1.
