Mobile robot's self-localization is an important part of robot technology research. This paper first briefly introduces several main methods of mobile robot's localization, and RSSI (received signal strength indicator) ranging principle. Then it proposes an experimental system which is used for mobile robot's localization based on wireless sensor network (WSN), and describes the experimental system's...
In this paper, a newly vision-based localization method for mobile robots is presented. The cost of hardware for this localization system is very low. Based on background subtraction and optical flow tracking, the presented method overcomes the shortcoming of general background subtracting method- being sensitive to noises and interferences of other mobile objects. Besides, the presented method is...
In this paper, a neural network approach named shortest path neural networks (SP-NN) is proposed for real-time on-line path planning. Based on grid-based map and mapping this kind of map to neural networks, this proposed method is capable of generating the globally shortest path from the target position to the start position without collision with any obstacles. The dynamics of each neuron is distinctive...
Teleoperation system plays an important role in executing tasks under hazardous environments. Unfortunately, most of the traditional teleoperation systems are expensive and bulky thus not suitable to provide real-world services. This paper introduces a novel architecture for the teleoperation of mobile robot based on Personal Digital Assistant(PDA) with mobility, facility and low cost. The architecture...
A map building method based on wireless sensor networks (WSNs) is presented in this paper which applies the technology of WSNs to the field of mobile robots. In our scheme, a series of factors blocking the mobile robot are considered carefully and besides, multiple information is employed to develop the practicability of maps. The general used gird map is provided through our method. Extensive simulations...
