Abstract

Abstract: The problem of dynamic angle detecting through sole sensor is analyzed. A dual-sensor data fusion technique is used to process the obtained angular data. This data fusion algorithm is simulated in Matlab and the simulation result is analyzed. In the process of dual-wheel self-balanced robot controlling, the data fusion algorithm is transplanted into MCU. Correct signal can be received through data fusion and the data is obtained from accelerometer sensor-MMA7260 and gyrostat sensor-MB54. The data coming from control system through experiment shows the validity and rationality of the algorithm.

Key words: robot, self-balance, data fusion, accelerometer, gyrostat
