1. A robot comprising:
- a case;
a first bumper coupled to the case, the first bumper being configured to sense an obstacle to be avoided; and
a second bumper configured to sense a surmountable obstacle over which the robot is configured to pass, wherein the second bumper is configured to be relatively rotatable with respect to the case.

17. A robot comprising:
-
a case; a first bumper coupled to the case, wherein the first bumper is configured to sense an obstacle by contacting the obstacle; and a second bumper provided at a different height than that of the first bumper, wherein the second bumper is configured to sense an obstacle by contacting the obstacle, wherein an obstacle to be avoided and an obstacle to be passed over are determined based upon obstacle signals sensed by the first and second bumpers, wherein the second bumper is configured to be relatively rotatable with respect to the case.

18. A method for controlling a robot, comprising:
-
providing a case, coupling a first bumper to the case such that the first bumper is configured to sense an obstacle, and providing a second bumper such that the second bumper is configured to sense an obstacle; and determining that the robot is configured to pass over an obstacle when the first bumper does not sense an obstacle signal and the second bumper senses an obstacle signal, wherein the second bumper is configured to be relatively rotatable with respect to the case. - View Dependent Claims (19)

20. A robot comprising:
-
a case; a first bumper coupled to the case; a first sensor to detect contact with the first bumper; a second bumper coupled to the case adjacent the first bumper; a second sensor to detect contact with the second bumper, wherein; (a) the first bumper is coupled to the case at a first height, (b) the second bumper is coupled to the case at a second height less than the first height, and (c) the first height is a height over which the robot is unable to pass when moved by a driver and the second height is height over which the robot passes when moved by the driver. - View Dependent Claims (21, 22, 23, 24, 25, 26)
