Robot localization research has always been the focus of the robotics research, but the shortcomings of the current robot localization method, poor anti-interference ability can't be accurate positioning, mainly due to environmental factors such as interference, position error will gradually increase. For these reasons, puts forward a weighted fuzzy PID control of mobile robot based on value since the positioning method. RTFL localization algorithm principle is given for the mobile robot model, a fuzzy PID controller is designed, according to the error and the rate of change size to choose the fuzzy positioning or PID positioning, for the intelligent mobile robot localization, in order to improve the robot positioning accurate. Through the simulation experiment results show that the fuzzy PID control of the robot from the localization method for mobile robot localization process has good effect, the practical effect is better.
