1. A motion platform, comprising:
a moveable plate;
a first driving mechanism;
a second driving mechanism; and
a fulcrum mechanism; wherein
the first driving mechanism and the second driving mechanism are connected to the moveable plate at a first support point and a second support point, respectively, and the fulcrum mechanism is connected to the moveable plate at a third support point;
the first support point, the second support point, and the third support point are non-collinear;
the first driving mechanism and the second driving mechanism are configured to cause the moveable plate to move in at least two degrees of freedom relative to the third support point; and
at least one of the first driving mechanism or the second driving mechanism includes a rotation driving unit and a power conversion unit, the power conversion unit being configured to convert a rotational motion of the rotation driving unit into a movement of a corresponding support point.
