  • Mobile robot with 360 degrees endless rotation type decoupled turret
    Publication number: 20060175099
    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).
