Abstract:
1. A traveling robot comprising: a body frame having a front wheel; a rear wheel disposed behind the front wheel with respect to a traveling direction of the robot; a rear frame which supports the rear wheel and is supported by the body frame to move vertically relative to a plane of the body frame; a driving wheel disposed between the front wheel and the rear wheel; a driving frame which supports the driving wheel and is coupled to the body frame by a hinge whose axis is parallel to an axis of the driving wheel; and a linkage member coupled to the driving frame to be contacted with the rear frame so that the driving wheel and the rear wheel are linked to each other and separated from the rear frame so that the driving frame and the rear frame are independent with respect to each other as the driving frame is rotated relative to the body frame.
