  • Apparatus for driving body with three-degree of freedom angular motion
    Patent number: 7975467
    Abstract: An apparatus for driving a body with 3-degree of freedom angular motion, comprises: a body connected to a fixing part so as to be rotatable centering around a pitch axis, a yaw axis, and a roll axis; a pitch axis driving unit for rotating the body centering around the pitch axis; and a yaw axis driving unit for rotating the body centering around the yaw axis. Since one of the pitch axis driving unit and the yaw axis driving unit restricts the body from rotating centering around the roll axis fixed to the body, the conventional roll-rotation restricting link is not needed between the body and the fixing part. Accordingly, a size of the apparatus is reduced.
