Abstract: The present disclosure relates to a movable table system comprising: a table; a first actuator for moving the table in a first direction; a second actuator for moving the table in a second direction; a first linear guide, which is coupled to the first actuator and the table, for guiding the table in the second direction; a second linear guide, which is coupled to the second actuator and the table, for guiding the table in the first direction; and a support portion for supporting the first actuator and the second actuator.

Abstract: The disclosure relates to a permanent magnet actuator comprising: a stator iron core having a space therein-side, and having a first wall and a second wall opposing the first wall; a movable element moving reciprocally between the first wall and the second wall, along a moving axis which connects the first wall and the second wall inside the space; a first magnetomotive force supplying body and a second magnetomotive force supplying body disposed respectively on the first wall and the second wall, so as to supply a magnetomotive force to the movable element for the reciprocal movement thereof, wherein, at least one of the first magnetomotive force supplying body and the second magnetomotive force supplying body selectively produces a bidirectional magnetomotive force; a permanent magnet disposed between the first magnetomotive force supplying body and the second magnetomotive force supplying body, and providing a coercive force to the movable element for maintaining the state thereof; and a driving circuit co

Abstract: A wearable apparatus for measuring position and action of an arm includes: a main frame worn on an upper body of a user; and an arm motion-measuring unit connected to a side of the main frame, having a plurality of joints, and worn on an arm of a user, in which at least any one of the joints of the arm motion-measuring unit has a straight-motional degree of freedom. Accordingly, an instructor can conveniently move both arms in the apparatus, can precisely instruct a two-arm robot in motions of the instructor's arms, can reduce learning time of the robot, and can make the robot quickly and accurately learn the motions.
