Mingyu Cui · Research and Exploration in Laboratory · 2014
To overcome the defects in traditional speedometer of wheeled autonomous mobile robot,such as wheel slipping,lower accuracy of the data with the accumulation of errors,this paper proposes a new method of detecting mileage for wheeled autonomous mobile robot based on magnetic navigation system and RFID technology. In the establishment of magnetic navigation system,this method is implemented. The method is to control the gap of laying magnetic markers and get the interval between the magnetic field of two neighboring magnetic markers,and then record the counts of not detecting the magnetic signal as wheeled autonomous mobile robot moves. it also combines the length of the gap among laying magnetic markers and modification value offered by RFID. Finally,the structure and the software and hardware design and implementation of main function modules in the system are given in detail,and the experiment results show that the system is effective and reliable.
