The Design of the Attitude Detection Algorithm of Underwater Robot

In this paper, by comparing and discussing the data fusion method, System adopts data fusion algorithm based on extended Kalman filtering for calculating the attitude of the underwater robot. Implementation of the algorithm is mainly through the three-axis accelerometer sensor, three-axis gyroscope sensor and three-axis magnetometer sensor composed of inertial measurement unit (IMU) module, signal processing to get the underwater robot posture information and real-time display.
