ABSTRACT:
An apparatus correcting a bias of a gyroscope that is mounted on a mobile robot and that measures an angular velocity of the mobile robot. The apparatus includes: at least one encoder respectively measuring a traveling velocity of a respective at least one wheel of the mobile robot; a modeling unit calculating an angular velocity of the mobile robot by using the measured traveling velocity; a bias presuming unit determining a confidence range by using difference values between the calculated angular velocity and the measured angular velocity, and calculating a presumed bias by using a value in a confidence range among the difference values; and a bias removing unit removing the presumed bias from the measured angular velocity.
