Collapsing
Just like the battle droid in the movie, the model collapses into a
small
size for storage. The knees fold back and the legs fold
forward. The hip joint is connected to a ratchet that locks the
legs in the folded position. The head and neck pivot down on a
4-bar linkage between the legs. The arms do not fold. When
.032a button on the back is pushed, the ratchet is released and the
model pops open
using rubber bands. The model is designed such that the rubber
bands are all shortest when the model is standing, therefore this is the
stable configuration towards which the rubber bands drive the model
when unlocked.
