Rotating platform and projection system

Abstract

The invention proposes a rotating motion mechanism comprising a first seat assembly, a second seat assembly, a rotating mechanism, and a first motion mechanism. The rotating mechanism comprises a base and a drive unit, wherein the drive unit is connected to the base to drive the base to rotate around its axis; the first seat assembly and the second seat assembly are arranged respectively on opposite sides of the base; the base can rotate around its axis and drive the first and second seat assemblies to rotate together; in which, the first motion mechanism comprises a first connecting unit and a first actuator; in which, the first actuator can drive the first seat assembly to rotate around its first inclined axis, and the first actuator can also drive the first seat assembly to rotate around its first rolling axis relative to the first connecting unit.
