Fig. 4From: Robot indoor location modeling and simulation based on Kalman filteringThe uniform motion of the robot is true. The robot moves from the point (0, 3) to the point (14, 3) along the line, and the movement azimuth θ = 0°. Without Kalman filter, the probability of positioning error is 80% within 2 m, while after Kalman filter, the positioning error is controlled within 1 mBack to article page
