Abstract: The present invention relates to a robot neck joint structure including: a head plate of a robot; a rolling drive unit for supporting the head plate and performing a rolling motion in a left and right direction; a pitching drive unit for supporting the rolling drive unit and the head plate and performing a pitching motion in a forward and backward direction; and a yawing drive unit for supporting the pitching drive unit, the rolling drive unit and the head plate and performing axial rotation at the same place. Therefore, since composite movements such as rolling, pitching and yawing of a head plate are allowed in order to implement motions like movement of a head of a human being, motions and expressions similar to the movement of a head of a human being can be implemented, and familiarity of persons to robots can be increased by stimulating interest and curiosity about the robots through a variety of performances.

Abstract: An ink-jet head mount to guide positions of ink-jet heads with a high precision and an ink-jet printing apparatus including the same. The ink-jet printing apparatus includes an ink-jet head having a plurality of nozzles to eject ink, an ink-jet head mount in which the ink-jet head is installed and is movable according to three-degrees-of-freedom, and a frame in which the ink-jet head mount is installed.

Abstract: A transporting apparatus which can horizontally transport a carrier using an air bearing of which a rotational degree of freedom is kept relative to a surface of a base. The transporting apparatus is movable along a surface of a base and includes an air bearing placed on a base, a connector connected to an upper part of the air bearing and provided with a supporter in a center thereof, the supporter having a flexure hinge structure to allow the air bearing to be freely rotated relative to the base, and the carrier supported by the supporter of the connector to be transported while keeping a level with respect to the surface of the base. With this configuration, a movement of the air bearing does not affect the carrier, thereby improving accuracy and reliability of the transporting apparatus.

Link support discs are set within a gap between outer surface of the central ball and inner surface of the hollow spherical body and fixed to each end of the lower link, and all the axes of the lower links and the upper link are coincident with a center point of the ball.

Abstract: A six-degrees-of-freedom parallel mechanism for micro-positioning work is disclosed. This mechanism freely performs a desired motion of translation and rotation of a moving platform using internal and external links actuated by linear actuators capable of precisely controlling the link positions, thus being effectively used as a 6dof parallel mechanism required to carry out a variety of micro-positioning works within a limited workspace. In the mechanism of this invention, a moving platform 10 is placed at an upper position, with a multiaxial spherical joint 40 mounted to the central portion of the moving platform 10. A base platform 20 is placed at a lower position of the mechanism. Three external links 30 couple the moving platform 10 to the base platform 20, while three internal links 50 couple the multiaxial spherical joint 40 to the base platform 20. In this mechanism, the internal links 50 are commonly coupled to the multiaxial spherical joint 40 so as to form a tetrahedral structure.
