Abstract: An apparatus for moving the center of gravity of a robot, and a system and method using the apparatus are provided. The apparatus includes a weight conveyor with a conveyed weight weighing a predetermined amount and disposed within the main body of the robot. The conveyed weight is conveyed in a predetermined direction to move the center of gravity of the robot, thus allowing a non-driven caster of the robot to surmount obstacles in its path and not become stuck while the robot is moving.

Abstract: A mobile system with cameras, a camera suspension, a method for measuring camera location information, and a camera mounting apparatus are provided. The mobile system with cameras comprising a camera mounting apparatus, the camera mounting apparatus includes a camera mounting unit which cameras join, a main body mounting unit attached to a main body of the mobile system; and connecting units for connecting the camera mounting unit with the main body mounting unit at a predetermined fixed point on one plane of the camera mounting unit, the connecting unit having an elastic unit and a damping unit for isolating the cameras from the movement of the main body mounting unit. The camera suspension can prevent the pictured moving image from severely shaking. In addition, the camera mounting plane information can be output to provide the camera location information in a real time. Therefore, the mobile system can obtain available image data during moving.

Abstract: The present invention relates to a mobile system and a moving method of the mobile system. According to the present invention, a natural period is measured from a vibration component signal generated by a force due to acceleration/deceleration of wheels, and the mobile system moves by applying an acceleration profile containing an acceleration period or a deceleration period based on the natural period. Therefore, the acceleration profile based on the natural period is applied such that vibration that is visible to a user is not generated during acceleration and deceleration of the mobile system. As a result, quality of the mobile system is improved.
