Ultrasonic devices have lots of uses in many fields, but they are rather limited in the indoor positioning fields. In order to solve the problems of the present ultrasonic positioning devices this paper illustrates an Ultrasonic Positioning and Analysis System for Automatic following and Locating Electric Carrier called UPASAFLEC in short. This paper adopts the least squares optimization method together with PI control. Highly accurate measurement and precise speed control are the advantages. This paper will mainly go through the design of the software and hardware of the UPASAFLEC and prove it useful with some experiments.
