Traveling apparatus and method of controlling the same

A traveling apparatus is provided with two wheels parallel each of which is driven independently, being controlled to be stable in an anteroposterior direction between the two wheels and traveling. The traveling apparatus includes a mechanism estimating an inclination of a plane where a pitch angular velocity sensor is horizontally installed with respect to a horizontal plane by using a sensor measuring a tilt of a vehicle body in a roll axis direction and a mechanism calculating a correct pitch angle by obtaining a yaw rate mixed in the pitch angular velocity sensor based on the estimated inclination and a turn velocity of the vehicle body and by canceling the yaw rate mixed.
