The Inclinometer Research for Attitude Control

In the mobile robot attitude control technology, the angle is an important property of attitude control, the study of high precision inclinometer is very essential. A high precision inclinometer which can automatically eliminate the zero offset is presented in this paper. The theory is based on the ancient method that the level bar can find horizon by rotating 180º. It is designed by step motor and MCU control technology. The theoretical basis, design structure and experimental results of the inclinometer are described. The experimental results show that the method can significantly improve the accuracy of the instrument.
