PHYSICAL MODELING SYSTEM FOR CONSTRUCTING AND CONTROLLING ARTICULATED FORMS WITH MOTORIZED JOINTS

A “construction set” consisting of active and passive parts connected by joints that can be manipulated to form an movable articulated assembly representing things like animals and skeletons. Each active part includes a position sensor for acquiring and storing position data specifying a sequence of positions assumed by the active part as the assembly is reshaped, and a controllable drive motor for moving the active part relative to a connected part in accordance with the position data.
