Abstract: A cleaning robot having an exhaust air feedback function can utilize the vacuum suction force generated by a suction motor as well as spray exhaust air onto the surface to be cleaned by circulating the air using the suction motor, thereby improving foreign material removal efficiency. The cleaning robot includes a suction unit, a suction motor for drawing in foreign materials from the surface to be cleaned, along with air, through the suction unit, a dust collector for capturing the foreign materials, so that the air is exhausted through the suction motor, and an exhaust air feedback unit for feeding the air. The cleaning robot also includes a spray nozzle unit inserted into the suction unit and placed on the leading end of the suction unit, the spray nozzle unit spraying the air fed by the exhaust air feedback unit, to the surface to be cleaned.

Abstract: The present invention provides a synchro-drive mobile robot base which allows a robot to accomplish a 360° endless rotation through a triple shaft mechanism, while a turret, a steering unit and a drive unit are decoupled from each other. The mobile robot base includes the turret (34) having thereon a turret motor (33), a drive motor (29) and a steering motor (19); the steering unit (10) which has a differential gear unit and transmits an actuating force generated from the steering motor (29) to a wheel case (41); a drive unit (20) which has a differential gear unit and transmits an actuating force generated from the drive motor (29) to the wheel (42); and a turret rotating unit (30) which transmits an actuating force generated from the turret motor (33) to the turret (34).

Abstract: The object of this invention is to provide a mobile robot base with a decoupled turret mechanism, including a turret (80), a turret motor (1) provided on the turret (80), an actuating motor unit provided on the turret (80) to actuate a plurality of wheels (90), an actuating gear train unit to transmit an actuating force generated from train (10) coupled between the turret (80) and the turret motor (1), and a differential gear train unit coupled to both the turret gear train and the actuating motor unit, so that the differential gear train unit subtracts the rotation of the turret (80) from the rotation of the actuating motor unit, thus transmitting a subtracted rotation to the plurality of wheels (90), and thus, only the rotation of the actuating motor unit is transmitted to the plurality of wheels (90). the actuating motor unit to the wheels (90).
