2. LITERATURE SURVEY:

The study and development of Robots used for the purpose of inspection and maintenance have increased drastically over the past few years. Many researchers have found new and better ways to perform the job. The various research work carried out over the past few years are: In line scout technology, which is built by Hydro Quebec sir, is an absolute system established in field for linemen. It is controlled by a semi-movable ground station consisting of transceivers set on a tripod and a portable table with a robust, military type field tablet PC (Montambault and Pouliot, 2006).It is independent till an extent and made for the work of transmission line. This device is a mature prototype tested in field conditions and can overcome a variety of obstacles in an efficient manner.

Thailand, 2001; S Peungsungwal et al.[4] This robot is very different. This is a small construction, built on the concept of gathering power from the magnetic field around the transmission line and using that power to propel a robot along the wire. The robot is little more than an iron core around the wire with a motor and 28 wheels to propel it and a minimum of other components (including a camera).This mechanism will for obvious reasons not clear any obstacle except maybe a compression splice. In its simplicity lies the beauty; this robot is cheap, simple and it does the job it set out to do but nothing else. It shows that at least this small robot can operate on a live wire without sustaining damage from the electric and magnetic fields. Generally, previous analysis shows that Arduino based mostly microcontroller applications are very productive in robotics design, development and implementation. It is very clear that Arduino created it simple to develop robotics applications simply, yielding folks to target FOSS applications.[3]

3. EXISTING SYSTEM:

At present, this work is completed by teams on foot, moreover as by chopper missions. Inspections on foot would really like many it slow and in some things square measure even impracticable area unit powerful piece of ground like mountains or steep valleys. The chopper missions square measure somewhat quicker but very dear, tedious, and hard, notably for the pilot since he needs to fly at minimum distance to the power lines. the probability of durable facet winds in addition turns this task into a dangerous state of affairs. In EE, live line in operation, together referred to as hotline maintenance, is that the upkeep of electrical instrumentality, usually operational at high voltage, whereas the instrumentality is energised. though this may be heaps of risky for personnel than functioning on electrical instrumentality with the power off, live-line maintenance techniques square measure used within the wattage distribution business to avoid the disruption and high economic costs of going to brag power to customers to perform essential periodic maintenance on transmission lines and completely different instrumentality. The first techniques for live line in operation were developed inside the first years of the 20th century, ways were developed inside the laboratory to alter field workers to come back into direct contact with high voltage lines.[1] Such ways area unit typically applied to alter safe work the best possible transmission voltages. In general, there are three ways of live line in operation that facilitate workers avoid the considerable hazards of live line in operation. In varied ways in which, all of them serve to forestall current flowing from the live instrumentality through the worker.

5.4 DC MOTOR:

A machine that converts DC wattage into mechanical power is understood as a DC motor. It’s operative depends on the principle that when a current carrying conductor is placed in a Magnetic field of force, the conductor experiences a mechanical force. The direction of this mechanical force is given by Fleming’s left-hand rule. According to Fleming’s left-hand rule when an electric current flow through a coil in a magnetic field, the magnetic force generates a torque that turns the DC motor. The direction of this force is perpendicular to each of the wire and also the magnetic field of force.It is that the most typically used rotatory actuator for generating continuous movements and whose speed of rotation will simply be controlled, creating them ideal to be used in applications were speed management, servo type control, and/or positioning is needed. A DC motor has two parts, a stationary part called "Stator" and a "Rotor" which is the rotating part.

5.5 SERVO MOTOR DRIVER:

The pulses have to be compelled to incline at frequencies of regarding 50Hz to 60Hz. For precise position management, the controller that's chosen must have timers that have the desired resolution. Also, if quite one motor should be controlled simultaneously; the processor clock should be quick enough. The electric load's tolerance of ripple dictates the minimum quantity of filtering that must be provided by a power supply. In some applications, high ripple is tolerated and so no filtering is needed. as an example, in some battery charging applications it's supply to implement a mains-powered DC power supply with nothing quite an electrical device and one rectifier diode, with a resistance with the output to limit charging current. A servo consists of a Motor (DC or AC), a potentiometer, gear assembly and a dominant circuit. First, we have a tendency to use gear assembly to cut back revolutions per minute and to extend torque of motor. When a servo motor shaft is initialized, the potentiometer knobs position is designated there is no electrical signal generated at the output port of the potentiometer, currently an electrical signal is given to a different input terminal of the error detector amplifying device. currently distinction between these 2 signals, one comes from potentiometer and another comes from different supply, are going to be processed in feedback mechanism and output are going to be provided in term of error signal. This error signal acts because the input for motor and motor starts rotating. currently motor shaft relates to potentiometer and as motor rotates that the potentiometer and it will generate an indication. thus, because the potentiometer’s angular position changes, its output feedback signal changes. when it slows down, the position of potentiometer reaches at a grip that the output of potentiometer is same as external signal provided. At this condition, there'll be no sign from the amplifying device to the motor input as there's no distinction between external applied signal and also the signal generated at potentiometer, and during this state of affairs motor stops rotating.

After giving the power supply we need to give instructions for the robot to work in the desired manner. Here we are using Bluetooth for serial communication. After connecting the vehicle to mobile through Bluetooth we are required to give a character such as ‘F’ for moving forward, ‘R’ moving backward, ‘S’ for stopping the vehicle these instructions are related DC motors for the movement of the robot. Characters such as ‘a’ or ‘b’ are to be given for the rotation of the camera connected to a servomotor if ‘a’ is given the camera moves to the left and if ‘a’ is greater than 175 degrees it is turned to 180 degrees if not ‘a’ is increased by 5 degrees. If ‘b’ is given as input .if ‘b’ is less than 5 degrees, then the camera moves to 0 degrees if not b is decreased by 5 degrees. Hence, we can operate both servomotor and DC motors in the desired manner.
