Abstract: An electronic fitness machine is provided, in which a user selects the output of the motor according to purpose by using reaction force generated contrary to the movement direction of a user by the drive of the motor. An electronic fitness machine comprises: a main body; a motor(200) installed at the main body; a motor output control unit including the controller controlling the load amount measuring unit, the input unit and output of the motor; a weight training part(400) in which a user applies the external force by grasping and walking; and a connection unit connecting the weight training part and the motor. The main body comprises 5 frames(120). The connection unit comprises a wire(300) connecting more than one pulley installed at the main body, the motor, and the weight training part.

Abstract: A tunnel cleaning truck is provided to clean almost all parts of a tunnel wall by recognizing attachments on the wall automatically and changing the position of a brush. A tunnel cleaning truck comprises a lift support(32), a plurality of ach lifts(40), a brush guard(50), a brush(60), a drive unit(70), a cleaning water tank(20), a cleaning water nozzle, and an obstacle sensor. The lift base rotates around an axis parallel to a truck(10). The arch lifts, which are mounted on the lift base, extend by several steps. The brush guard, whose top is open, moves along the lifts. The drive unit extends and contracts the lifts and causes the brush guard to move along the lifts. The brush rotates in the brush guard, sweeping foreign matters attached on the curved wall. The obstacle sensor is installed at the brush guard to sense attachments on the wall of the tunnel.
