This paper describes the design and development of remote communication system for mines detector robot. This project uses a PIC18F4580 microcontroller to control the robot movements and functions. A metal detector will be attached to the robot. The robot will have two operating modes; automatic and manual mode. In automatic mode, the robot will move according to a predefined track. When the robot is moving, the system produces feedbacks given by the sensors on the robot to the remote computer about the surroundings and when potential land mines are detected. In manual mode, the robot will be fully controlled by the remote computer for decision making process. All the controls and monitoring of data are displayed in a graphical user interface (GUI). The wireless module proposed is the XBee RF modules. The XBee modules were found to perform with optimum data transfer reliability at the range equals to 25% of its maximum communication range.

Nowadays, mobile robot platforms are utilized in various fields not only for transportation but also for other diverse services such as industrial, medical and, sports, etc. Mobile robots are also an emerging application as sports field robots, where they can help serve players or even play the games. In this paper, a novel caddie robot which can autonomously follow the golfer as well as provide useful information such as golf course navigation system and weather updates, is introduced. The locomotion of the caddie robot is designed with two modes: autonomous human following mode and manual driving mode. The transition between each mode can be achieved manually or by an algorithm based on the velocity, heading angle, and inclination of the ground surface. Moreover, the transition to manual mode is activated after a caddie robot has recognized the human intention input by hand. In addition, the advanced control algorithm along with a trajectory generator for the caddie robot are developed taking into consideration the locomotion modes. Experimental results show that the proposed strategies to drive various operating modes are efficient and the robot is verified to be utilized in the golf course.

Visible light communication technology is a emerging wireless and optical communication technology developed after invention and application of white LED.In this paper, we have a research based on indoor visible light communication system of lighting white LED,discuss of the visible light communication channel characteristics,detailedly analysis of the indoor visible light communication link. This paper focuses on the modulation and demodulation method applied to visible light communication. In the past visible light communication is mainly used off keying modulation,however, the data transfer speed is limited due to the influence of ISI .This paper presents a solution based on OFDM modulation and demodulation, to reduce the impact brought from inter-symbol string under high data transfer speed.Based on data analysis and computer simulation,the program presented in this paper can be used as indoor lighting and high-speed data transmission.Finally, give scheme to achieve visible light communication modulation and demodulation,provide a theoretical basis for further experiments.

Scalable Communication

Background: Network on chip is proposed as new reusable and scalable communication system for applications with important number of IPs. The NoC architecture characteristics are based on several factors: the implementation strategy of IPs, the power dissipation, the placement of IPs, data transfer time, the requirements of the given application, etc. The N×M Mesh topology combined with the XY routing algorithm are generally chosen in many studies. Hardware IPs proposed in the literature, for various applications as example video encoders, operates at different frequencies and generally implemented according to several strategies and different bus sizes. Connecting these IPs using the same communication system is very difficult. Methods: In this paper, we present a new topology based on multi-layer mesh topology and adapted for video coding applications. The proposed topology exploits the video coding information regarding groups of cores that communicate through two cores only. The idea is to use a specific NoC for each group of cores and connect the NoCs with bridge in the positions of two communication cores. The choice of parameters in each NoC depends on the characteristic of IPs in the same group in order to maximize communication adaptivity and performance. Results: Synthesis results show that the proposed multi-layer mesh topology NoC uses much less resources than the traditional NxM mesh topology NoC. Conclusion: This reduction in term of resources is assured by the considerable reduction in the length and number of global interconnects, resulting in an increase in the performance and decrease in the power consumption and area of wire limited circuits.

Power Line Communication (PLC) uses the available power line as a communication medium. The purpose of this chapter is to present the salient features, current trend and future scope of PLC with emphasis in the Indian context. Unlike other channels available, power lines are harsh media for data transfer and require efficient modeling and simulation techniques to propose and implement suitable mitigation schemes for achieving acceptable performance. Designed equipments have to adhere to strict mandates at the national and international levels to account for issues related to electromagnetic compatibility (EMC). In spite of this, PLC is expected to occupy an important place in the networking market in applications of smart grid and as a component of heterogeneous/hybrid communication system. The chapter is also backed by results from experiments carried on a typical power line in a test site with a presentation of noise, transfer characteristics, modeling and an estimate of the channel capacity.
