Mobile Robot Regional Positioning Design And Analysis

Low flexibility has been the primary problem for the further application of regional positioning technology.The main purpose of this paper is to explore an active regional location method through design and analysis of mobile robot regional location.This paper includes three parts:positioning technology analysis and implementation,mobile robot design,algorithm research and testing.In positioning technology analysis and implementation,after the analysis of wireless positioning technology,this paper implements the zigbee module hardware design and software development based on zigbee technology.In the structural design process,based on triz theory,the design of the crawler-quadrotor structure as the whole structure of mobile robot.In the control design process,based on the analysis of mobile robot movement,the dual-loop motor speed control method and the ring control method are designed:In the algorithm research and testing.based on the analysis of experimental data,the double mean value distance measurement fitting algorithm and the double mean value distance measurement KNN algorithm are designed.The experimental results shovs that the double mean value distance measurement KNN algorithm is better than the double mean value distance measurement fitting algorithm.Based on the distance measurement algorithm and the trilateration method,an active positioning experiment was carried out.It was found from the experimental results that the positioning error was less than one meter.Firom above research can be concluded:this design of mobile robot localization is an effective active regional positioning method,which is valuable for impro,ving the flexibility of regional positioning technology.
