A swarm robot and a sweeping method using the swarm robot are provided. The swarm robot removes a plurality of objects in a given sweeping area, and at least two swarm robots collaborate to remove the individual object. The swarm robot searches the sweeping area, detects environment information of the sweeping area, locates the swarm robot in the sweeping area, generates a local map and an object map using the environment information and the acquired position, moves to the object according to the local map and the object map, and removes the object.

The present invention relates to a stage, particularly to, a stage which is able to move minutely, having a rigidity-improved transfer part. A stage includes a work table on which a working object is placed, a motor configured to provide a rotational force, a shaft rotated by the motor to transfer the work table, a linear moving part configured to be expandable to linearly move the shaft in an axial direction, the linear moving part having a hollow to insert an end of the shaft therein, and an expanding part configured to be expandable as far as the shaft is moved by the linear moving part.

An imaging apparatus includes: a rotator having a shape of a perforated circular plate and rotating around a rotating axis of a center of the perforated circular plate; and a supporter having a perforated circular plate and one side of which is connected to one side of the rotator such that the rotator is restricted only to rotation movement. The supporter includes a supporter opening/closing part a part of which is separated along the rotating axis and then rotates by a predetermined angle around the rotating axis, and the rotator includes a rotator opening/closing part a part of which integrally moves with the supporter opening/closing part.

A gantry positioning device for connecting a gantry and a supporter together of an imaging system includes: a linear translation positioner for translating the gantry vertically with respect to the supporter; a first rotation positioner for rotating the gantry about a first axis which passes horizontally an iso-center of the gantry with respect to the supporter; and a second rotation positioner for rotating the gantry about a second axis which passes vertically the iso-center of the gantry with respect to the supporter. The first rotation positioner includes: a tilt guide which is formed along an arc having a center on the first axis; and a tilt block which is connected to the tilt guide so as to be rotatable about the first axis.
