For the problem that the extended Kalman filter is difficult to design and prone to diverge, the unscented Kalman filter algorithm based method is presented to solve the problems of the filter design and convergence. The error from the low-cost inertial gyro and accelerometer is compensated to achieve optimal attitude estimation. The filtered model is applied to the two-wheeled self-balanced robot system.
