Abstract: A mobile robot includes a telescopic lift mounted on the outside of a main body of the mobile robot, the telescopic lift being extendable in a height direction; a first sensor package installed at an upper end of the telescopic lift; and a second sensor package installed at the upper end of the telescopic lift. The mobile robot is configured to collect information regarding an inspection target, which is installed at a high-altitude location on a particular floor level of a semiconductor fabrication plant, using the second sensor package, prevent the collision of the telescopic lift or the first sensor package of the mobile robot with the inspection target and/or stop the telescopic lift when the second sensor package collides with an object at the high-altitude location or with the inspection target, and conduct an unmanned inspection of the inspection target, including autonomously driving.
