Mobile robot
First Claim
1. A mobile robot, comprising:
- a body;
a wheel connected with the body and configured to move in first and second directions relative to the body; and
a wheel guide unit coupled at a first end thereof to the body and at a second end thereof to a hub of the wheel, the wheel guide unit being contracted when the body is spaced apart from a surface on which the mobile robot moves, wherein the wheel guide unit expands to allow the wheel to be in contact with the surface when the body comes into contact with the surface.

Abstract
A mobile robot having wheels which maintain contact forces against a surface even when the mobile robot meets an obstacle on the surface and a body of the mobile robot is forced up against the obstacle. The mobile robot easily surmounts the obstacle on the surface, without requiring any sensors, any specific controller, any specific traveling unit to surmount over the obstacle, or any specific drive unit to drive the specific traveling unit. The mobile robot includes the body, the wheels connected with the body which move arcuately relative to the body, and a wheel guide unit coupled at a first end to the body and at a second end to a hub of each of the wheels. The wheel guide unit is contracted when the body is spaced apart from the surface on which the robot moves. However, the wheel guide unit expands to allow the wheel to be in contact with the surface when the body comes into contact with the surface.

5. A mobile robot, comprising:
-
a body;
a wheel connected with the body and which moves in first and second directions relative to the body;
a power spring connected with the body; and
a wheel guide unit coupled at a first end thereof to the power spring and at a second end thereof to a hub of the wheel, the wheel guide unit being contracted when the body is spaced apart from a surface on which the robot moves, wherein the wheel guide unit rotates, when the body comes into contact with the surface to allow the wheel to be in contact with the surface.

6. A mobile robot, comprising:
-
a body having a first end and a first lower surface near the first end, the first lower surface being inclined from a horizontal plane of a bottom-most portion of the body;
a wheel connected with the body and which moves in first and second directions relative to the body; and
a wheel guide unit coupled at a first end thereof to the body and at a second end thereof to a hub of the wheel, the wheel guide unit being contracted when the body is spaced apart from a surface on which the mobile robot moves, wherein the wheel guide unit expands to allow the wheel to be in contact with the surface when the body comes into contact with the surface. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
