Transformation scheme

A transformation scheme is the process by which the parts of an individual Transformer move and shift in relation to each other to convert it from one mode to another. Though some Transformers share identical or similar transformation schemes, most are unique to the individual. The amount of detail this gets in fiction varies widely, from “cheatsy” animation utilizing motion blur to the highly-detailed computer animation in the live action movies. In the toys this concept can change the way a toy looks in either mode drastically (see: shellformer, kibble).

Those legs have to go somewhere when you turn into a car.
