In this article, the relations among mission, basic requirements, contour and distribution of the configuration design are discussed, and the functions of model rigging is introduced, too.

Before rigging we would manually place the concept model in certain positions to illustrate how it would hover, land, and lower itself into the vine bushes.

Animating an articulated three dimensional human model currently requires manual rigging to specify its internal skeletal structure and to define how the input motion deforms its surface.
