1. A horizontally movable 7-axis multi-joint robot, comprising:
a robot arm to which a plurality of arm units is coupled through multi-joints;
a transport member, which is movable along a guide rail installed in a horizontal direction wherein the robot arm is coupled thereto;
a base seated on the transport member, to which the robot arm is coupled; and
a weight balancing arm prepared such that any one of the above arm units is eccentrical on the base, which has a weight pendulum prepared in opposite to the robot arm, thereby preventing the weight from being concentrated toward the robot arm.
