[attachment=27639]
INTRODUCTION
The goal of this research is to develop mobile robot and software systems to support the firemen, police, and rescue agencies with reconnaissance, site evaluation, and human detection.
1.1 WORKING PRINCIPLE:
The working principle of the module is explained in 2 units, they are
1. Controlling unit
2. Robotic module
CONTROLLING UNIT:
The controlling unit is responsible for controlling all the operation done in the robotic module. The movement of robot is controlled by four switches on controlling unit. It has 4 push button switches connected directly to the transmitter, which are responsible for movement and direction control of robotic module each switch will control one motor.
Where ever the robotic module goes it sends real time video and audio information of the particular environment .The robotic module has day vision camera with built in micro phone which sends video and audio information to the controlling unit .the controlling unit has receiver (operates at 2.4 GHz) with tuner and it is directly connected to the computer to view the real time video with audio, which helps rescue team to know the surrounding environment of the robotic module.
ROBOTIC MODULE:
The robotic module consists of microcontroller, driving units, night vision camera, firing module (LASER), audio receiver unit and trans-reception unit. The block diagram of robotic module .
This is a multipurpose unmanned ground vehicle used for surveillance purpose. In this section we firstly discuss about the receiver fallowed by decoder which is responsible for receiving all the commands from the controlling station. After receiving commands it sends that commands to its respective sections.
If the user wants to move the vehicle he sends command through controlling unit for the robotic module containing four gear motors to drive the wheels in any specified direction. To drive all the 4 motor we use motor driver circuit, which consists of 2 motor drivers IC L298. Each driver IC will control 2 dc motors.
EMBEDDED SYSTEMS
OVERVIEW:
An embedded system can be defined as a computing device that does a specific focused job. Appliances such as the air-conditioner, VCD player, DVD player, printer, fax machine, mobile phone etc. are examples of embedded systems. Each of these appliances will have a processor and special hardware to meet the specific requirement of the application along with the embedded software that is executed by the processor for meeting that specific requirement.
CHARACTERISTICS:
The embedded software is also called “firm ware”. The desktop/laptop computer is a general purpose computer. You can use it for a variety of applications such as playing games, word processing, accounting, software development and so on.
Embedded systems do a very specific task, they cannot be programmed to do different things. Embedded systems have very limited resources, particularly the memory. Generally, they do not have secondary storage devices such as the CDROM or the floppy disk. Embedded systems have to work against some deadlines. A specific job has to be completed within a specific time.
PLATFORM:
There are many different CPU architectures used in embedded designs. This in contrast to the desktop computer market which is limited to just a few competing architectures mainly the Intel/AMD x86 and the Apple/Motorola/IBM Power PC’s which are used in the Apple Macintosh. On common configuration for embedded systems is the system on a chip, an application-specific integrated circuit, for which the CPU was purchase as intellectual property to add to the IC’s design.
OVERVIEW OF EMBEDDED SYSTEM ARCHITECTURE:
Every embedded system consists of custom-built hardware built around a Central Processing Unit (CPU). This hardware also contains memory chips onto which the software is loaded. The software residing on the memory chip is also called the ‘firmware’
