A lifting judgment for a robust dead reckoning system is proposed for a wheeled mobile robot when the robot is carried by the person. In this system the position of the robot on the ground is estimated by an odometer, whereas that in the air is estimated by an inertial sensor. The estimation mode is switched by the lifting judgment. Neither enough accuracy nor itliability is actually obtained though it is thought that the lifting judgment can be decided by only height information. This is attributed to the fact that their are cumulative errors due to the bias drift in the height calculation from the integration of the value of the acceleration sensor Therefore, a PSD distance sensor was installed for only the lifting judgment in the previous implementation. This paper proposes a lifting judgment method with a boosting algorithm by using the information on the internal sensors such as accelerometer, gyro sensor, and wheel encoder without the PSD distance sensor Furthermore, experimental results using an actual mobile robot are given to demonstrate the effectiveness of the present method.
