AUTOMATIC RAIN OPERATED WIPER AND HEAD LIGHT DIM & BRIGHT CONTROLLER

INTRODUCTION

A wiper generally consists of an arm, pivoting at one end and with a long rubber blade attached to the other. The blade is swung back and forth over the glass, pushing water from its surface. The speed is normally adjustable, with several continuous speeds and often one or more "intermittent" settings. Most automobiles use two synchronized radial type arms, while many commercial vehicles use one or more pantograph arms. Mercedes-Benz pioneered a system called the Monoblade in which a single wiper extends outward to get closer to the top corners, and pulls in at the ends and middle of the stroke, sweeping out a somewhat 'W'-shaped path. Some larger cars are equipped with "hidden" (or "depressed-park") wipers. When wipers are switched off, a "parking" mechanism or circuit moves the wipers to the lower extreme of the wiped area, near the bottom of the windscreen, but still in sight. To hide the wipers, the windscreen extends below the rear edge of the hood, and the wipers park themselves below the wiping range at the bottom of the windscreen, but out of sight.

falls the driver has to sense it and switch on the button that actuates the wiper. Wipers may be powered by a variety of means, although most in existence today are powered by an electric motor through a series of mechanical components, typically two 4-bar linkages in series or parallel. Vehicles with air operated brakes sometimes use air operated wipers, run by bleeding a small amount of air pressure from the brake system to a small air operated motor mounted just above the windscreen. These wipers are activated by opening a valve which allows pressurized air to enter the motor.

  So in conventional wiper system, when the rain in our project we have installed a sensor to detect the rainfall and actuate the wiper automatically.

UNMANNED  UNDERWATER  SURVEILLANCE  ROBOT

Abstract
Unmanned underwater surveillance robot is designed to fulfill the need for autonomous solution of underwater control. This study is performed as a bachelor graduation thesis project of IZTECH and can be counted as developed prototype of industrial surveillance robots. Aim of the project is to increase knowledge of students on remotely operated vehicles (ROV) and teach them how teamwork is accomplished. Therefore, each subtask that has done in this project is 100% work-based and financially supported by students.

Introduction
Surveillance is key element of control and risk management. Especially in areas where conditions are not suitable for human or there are risks against human health, need of surveillance and control is even more significant than it is already. As engineers and designers are volunteers and responsible persons for serving humans and providing solutions to problems, there has to be solution that has been created and provided by them.
Surveillance underwater has increased it’s importance since number of fish farms started to increase as well. Back then, control of these farms was done by divers but apart from divers, nobody was able to see what is going on underwater. So the need has come up and engineers developed the solutions. ROV’s or unmanned surveillance robots are high-tech solutions to this problem and provide reliable and accurate data to fish farms.

In this project, we have provide solution for underwater surveillance. Our robot is able to dive underwater (15m), move and record data at desired depths.
Following parts of this thesis will briefly summary the work done from the beginning of project. In addition, design criteia and constraints, work breakdown structure, linear responsibility chart, comments and budget information will be provided.
