    • A micro robot includes first and second masses, each having a first contact surface having a first frictional coefficient and a second contact surface having a second frictional coefficient and formed to be inclined by a predetermined angle with respect to the first contact surface, the first and second contact surfaces being formed at the lower portion of the mass corresponding to a surface of a target object, and an actuator provided between the first and second masses for periodically changing the distance between the first and second masses and enabling the first and second contact surfaces of the first and second masses to selectively contact the surface of the target object in synchronization with a periodic change in distance between the first and second masses. Thus, the micro robot is moved by the change in the distance between the masses constituting the micro robot together with the periodic change in friction between each of the masses and the surface of the object on which the micro robot moves, instead of using wheels or caterpillar tracks. Thus, the protective cover can protect the power source.

    • A method, medium and electronic device using a three-axis geomagnetic sensor for quick and accurate measurement of an azimuth angle includes a first calculating unit to calculate distances between an output value of the three-axis geomagnetic sensor and an offset value, and a controller to determine that the offset value is distorted when the distance calculated by the first calculating unit deviates from a predetermined range of radius values. The electronic device can further include a sampling unit to sample output values of the three-axis geomagnetic sensor when the calculated distance deviates from the predetermined range of radius values, and a second calculating unit to calculate a mean value and a standard deviation value for distances between the sampled values and the offset value. The controller may determines that the offset value is distorted when the mean value and the standard deviation value deviate from predetermined permissible ranges.
