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.

Abstract
A traveling robot includes a body frame having a front wheel; a rear wheel which is disposed on a rear side of the front wheel along a traveling direction; a rear frame which supports the rear wheel and is supported by the body frame so as to move vertically; a driving wheel which is disposed between the front wheel and the rear wheel in the traveling direction; 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 which is coupled to the driving frame to be contacted with or separated from the rear frame as the driving frame is rotated relative to the body frame.

15. A traveling robot comprising:
-
a body frame having a front wheel and at least one stopper; and at least one driving assembly disposed between the front wheel and the at least one stopper, the at least one driving assembly comprising; a drive wheel to drive the robot to travel, a drive frame connected at a first end to the drive wheel and having a hinge disposed at a middle portion thereof to connect to the body frame to enable the drive frame to pivot with respect to the body frame such that a second end thereof and the drive wheel pivot with the drive frame, a rear frame body that extends through the corresponding at least one stopper and is connected at a first end to a rear wheel and has a sliding part connected at a second end thereof wider than the rear frame body to be stopped by the corresponding stopper, and a linkage member connected at one end to the second end of the drive frame to pivot with the drive frame and including another end that contacts the sliding part of the rear frame body to move the rear wheel in a substantially perpendicular direction with respect to the body frame such that when the drive frame pivots by a predetermined amount, the drive wheel and the rear wheel move in the direction substantially perpendicular with respect to the body frame. - View Dependent Claims (16, 17, 18, 19)
