1. A motion control system for controlling a motion mode of a second motion body by using a motion mode of a first motion body as a prototype, said first motion body and said second motion body being separate motion bodies, comprising at least one processor, the at least one processor further comprising: a first processing element which repeatedly determines a fraction of an extrinsic factor representing an environment encircling the first motion body as an extrinsic feature factor and a fraction of an intrinsic factor representing the motion mode of the first motion body as an intrinsic feature factor for each motion reiterated by the first motion body in response to a different environment, and defines a model representing a consecutive correlation of the extrinsic feature factor and the intrinsic feature factor on the basis of a discrete correlation of the extrinsic feature factor and the intrinsic feature factor obtained from the determination result; and a second processing element which determines an extrinsic feature factor contacted by the second motion body, calculates a second motion body intrinsic feature factor on the basis of the determination result and the model defined by the first processing element, and controls the motion mode of the second motion body to implement at least the calculated second motion body intrinsic feature factor, wherein the first processing element evaluates a deviation degree between the discrete correlation of the extrinsic feature factor and the intrinsic feature factor obtained from the determination result and the consecutive correlation of the extrinsic feature factor and the intrinsic feature factor defined according to the discrete correlation, and defines the model representing the consecutive correlation on a condition that the deviation degree is not greater than a threshold value.
