Abstract
The present invention relates to a four degrees of freedom motion apparatus, and more particularly, to a four degrees of freedom motion apparatus capable of implementing three degrees of freedom (pitch, roll, heave) motions by three actuators positioned at a lower plate and a center plate, and between the lower plate and the center plate, and a spline, and additionally implementing an one degree of freedom (sway) motion by a connecting means provided between the center plate and an upper plate.
Claims5
A four degrees of freedom motion apparatus, comprising:
- a lower plate contacting the ground;
- a center plate positioned while being spaced apart from the lower plate toward an upper side of the lower plate;
- three actuators positioned between the lower plate and the center plate, and configured to implement three degrees of freedom motions according to driving forms thereof;
- a spline positioned between the three actuators, and having a lower end bolt-fastened to the lower plate, and an upper end coupled to a lower portion of the center plate by a universal joint;
- an upper plate positioned while being spaced apart from the center plate toward an upper side of the center plate;
- and
- a connecting means configured to implement an additional one degree of freedom motion through a point-contact or surface-contact of the center plate and the upper plate.
