Abstract:
Using wireless sensors as landmarks for mobile robot localization has many advantages, but the process of measuring the distance between the robot and wireless sensor is susceptible to environmental disturbance. To solve this difficult problem, the radio frequency signal decay theory was analyzed, and an adaptive signal decay range model was established for wireless landmarks based on the online learning method. The model learning was completed online, so the effect of the environmental factors on the decay of wireless signal transmission was included in the online modeling process; correspondingly, the adaptive ability of the model was improved. In addition, the identity numbers of different wireless landmarks were also input into the artificial neural network model so that differences among certain sensors were considered. Experiments show that the proposed modeling method is effective for improving wireless sensor ranging precision.
