A multi-disciplinary research project is being undertaken at NPS to develop a semi-autonomous robotic system to detect and clear land mines and Unexploded Ordnance (UXO). The robotic system under development consists of a land vehicle, an aerial vehicle, and a ground-based control station. Reliable communication between these three stations is needed. A traditional wire-based network requires that the vehicles be tethered and severely limits the mobility of the vehicles. A wireless Local Area Network (LAN) is proposed to provide communications between the control station and the vehicles. The objective of this thesis is to develop the physical (hardware) and logical (software) architecture of a wireless LAN that accommodates the needs of the mine/UXO project. Through an analysis of wireless modulation techniques, a market survey of wireless devices, and a field testing of wireless devices, a wireless LAN is designed to meet the technological, performance, regulation, interference, and mobility requirements of the mine/UXO project. Finally, the wireless communication protocols and the development of an error-free application protocol (specified by a FSM model and implemented in ANSI C code using Windows socket network programming) completes the wireless LAN implementation.

Wireless Communication 1 Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors. Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal. In radio, multiple-input and multiple-output, or MIMO (/ ˈ m aɪ m oʊ, ˈ m iː m oʊ /), is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards including IEEE n (Wi-Fi), IEEE ac (Wi-Fi), HSPA+ (3G), WiMAX, and Long Term.
Abstract: SWARM robotics or multi robot systems is a novel approach to the coordination of large numbers of relatively simple robots which takes its inspiration from social insects - ants, termites, wasps and bees etc. Local communication can be achieved by different types of wireless transmission systems. Different types of sensing system, Communication system and design approaches are . Wireless communications, System using radio-frequency, infrared, microwave, or other types of electromagnetic or acoustic waves in place of wires, cables, or fibre optics to transmit signals or data. Wireless devices include cell phones, two-way radios, remote garage-door openers, television remote controls, and GPS receivers (see Global Positioning System).

These systems transmitted infor-mation over line-of-sight distances (later extended by telescopes) using smoke signals, torch signaling. This project outlines the strategy adopted for establishing two kinds of communications; one for wireless communication between a mobile Robot and a remote Base Station, another for serial communication between a remote Base Station and a GUI Application, PC.
TekBot is a low cost mobile Robot built by Oregon State University which in its. The System “Wireless Technology Based Robot Communication System” is developed for the purpose of achieving tasks that are almost impossible for the humans and for using them in hazard prone areas.
The system consists of a master robot, slave robot, voice module and the. Wireless Communication Wireless communication involves transferring information from your controller to a robot without them being physically connected to the controller.
Wireless communication range can be as short as few centimeters to as long as millions of kilometers depending on the technology used.

allows multiple clients diffused around the antennas to access wireless communications. Therefore, omnidirectional antennas are often considered to be suitable for communications in a multi robot system. Whereas omnidirectional antennas provide a wide coverage area, they cannot deliver long communications distances.
Also. Hence, it has been agreed to use common interfaces and standards for communication. The Robot Operating System (ROS) is used as a communication layer, supported by.

As you are interested in sending images, you will need a wireless communication device with higher data rate. So as of i know to send a continuous bulky data you can go with WiFI solutions. i.e. 5 hours ago Forth has incorporated sonar technology with the robot’s system to detect and avoid obstacles underwater to enable the robots to be used near ‘critical infrastructure’.
Alongside this Forth has developed an Enabling Technology which provides Launch and Recovery, recharging and high bandwidth communications for the ROV.
The robots also may work cooperatively, locally exchanging data in a multi-robot system and performing collaboratively a given task, thus requiring low-power and long-range wireless communication. Long-range wireless communication is also required in robotics remote-sensing systems, where mobile robots are collecting data far away in an unknown.
