Abstract: A kinetic sculpture and an intelligent control system are provided which comprise a plurality of movable bases (500), and the movable bases are arranged radially along a circumferential direction around a centerline disposed vertically; a bearing unit (400) is mounted on each of the movable bases (500), a vertical column (100) is mounted on the bearing unit (400), and a blade unit (200) is disposed on the column (100); the bearing units (400) move the columns (100) along the moving paths on the respective movable bases toward the position of the centerline or away from the position of the centerline to achieve combination or separation; the column systems correspondingly control each of the columns (100) to move. The kinetic sculpture enables the blades (201) of the kinetic sculpture to present a contour shape in gathered and separated states.

Abstract: A component of a kinetic sculpture is provided which comprises a bearing unit (400), a column (100) vertically disposed on the bearing unit (400) and a blade unit (200) disposed on the column (100); the blade unit (200) comprises a plurality of blade groups spaced apart along an axial direction of the column (100), the blade group comprises one or more movable blades (201-S), and a blade driving unit (300) for driving the movable blades (201-S) in a same blade group to freely switch between a gathered state and a separated state is disposed on the column (100).
