ROBOTICS
Introduction
Robotic means TO MAKE MACHINE in such a way that can work SUFFICENTLY,SMARTLY without making human to work hard.
In Sort Robotics is the field which is the future of the next generation.
It mainly includes 2 branches:
1 E.C.(To make the circuit and the logic of operation)
2 Mechanical (To make the structure)
Basic Concepts
Analog Signal
Digital signal
Analog to Digital converter
Sensors
Switching
Analog Signal
Digital Signal
To make the digital signal we have to put condition of analog signal.
It is very easy to process the data if it is in form of digital and signal processing is much easier.
A/D Convertor
It is the page link to convert the analog signal into digital.
By conditioning the analog signal we can get the digital signal
For conditioning we uses op-amp and encoder.
Sensor
Sensors are used to sense the parameter.
They are nothing but the one type of
“TRANSDUCERS”.
They covers one type on energy into other type.
To sense the different type of parameters different sensors are used.
Sensor Types
Sensory transduction may be carried out by physical principles .
Some of them are …
Mechanical sensors
Magnetic and Electromagnetic sensor
Thermal sensor
Chemical and bio-chemical transducer
Acoustic sensor
Motion sensor
IR sensor
It is most widely use in
line-follower
Wall follower
Edge Avoider
Maze clearing Bot

INTRODUCTION
Recognizing, sharing, and reusing robot behaviors across multiple robot platforms with various similarities are challenging. Although descriptions for objects [e.g., computer-aided design (CAD) models and recognition models] and environments (e.g., geo coordinates, local coordinates, and feature maps) are largely interchangeable across different robot hardware, robot task descriptions are typically hardware dependent.
HISTORY
The concept of wearable computing was first brought forward by Steve Mann, who, with his invention of the 'Wear Comp' in 1979 created a pioneering effort in wearable computing. Although the effort was great, one of the major disadvantages was the fact that it was nothing more than a miniature PC. Absence of lightweight, rugged and fast processors and display devices was another drawback
WEARABLE COMPUTERS
Wearable computers are miniature electronic devices that are worn by the bearer under, with or on top of clothing. This class of wearable technology has been developed for general or special purpose information technologies and media development. Wearable computers are especially useful for applications that require more complex computational support than just hardware coded logics.

1. INTRODUCTION
Robotic manipulators are widely used to replace human operators in tasks that are repetitive in nature. However, there are many tasks that are non-repetitive, unpredictable, or hazardous to the human operators. Clearing up a nuclear power plant leak or exploring the extreme depths of ocean are just some examples. The most developed robot in practical use today is the robotic arm and it is seen in applications throughout the world. Robotic arms are used to carry out work in outer space where man cannot survive and also used to do work in the medical field such as conducting experiments without exposing the researcher.
ROBOT
A robot is an artificial or virtual agent which in the physical form gives the appearance of being alive. The artificial form (the physical agent) is an electro-mechanical or bio-mechanical device or group of devices that can perform autonomous or preprogrammed tasks while interacting with its surrounding environment using sensors. The word "bot" in the term is a reference to the "robotic", mundane, repetitive tasks that the applications perform.A robot may act under the direct control of a human, such as the robotic arm on a space shuttle, or autonomously under the control of a programmed computer. Robots may be used to perform tasks that are too dangerous or difficult for humans, such as radioactive waste clean-up, or may be used to automate mindless repetitive tasks that should be performed with more precision by a robot than by a human, such as automobile production.
ROBOTICS:
"Robot" is also used in a general sense to mean any machine that mimics the actions of a human (biomimicry), in the physical sense or in the mental sense. Robotics is the science and technology of robots, their design, manufacture, and application. Robotics requires a working knowledge of electronics, mechanics, and software. A person working in the field is a roboticist. The word robotics was first used in print by Isaac Asimov, in his science fiction short story "Runaround" (1941). Although the appearance and capabilities of robots vary vastly, all robots share the features of a mechanical, movable structure under some form of control.
ADVANTAGES:
1. Quality:
Robots have the capacity to dramatically improve product quality. Applications are performed with precision and high repeatability every time. This level of consistency can be hard to achieve any other way.
2. Production:
With robots, throughput speeds increase, which directly impacts production. Because robots have the ability to work at a constant speed without pausing for breaks, sleep, vacations, they have the potential to produce more than a human worker.
3. Safety:
Robots increase workplace safety. Workers are moved to supervisory roles, so they no longer have to perform dangerous applications in hazardous settings.

What is a Robot
A re-programmable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks.”
History
1940: Westinghouse Electric Corp. creates
two of the first robots that use the electric motor for entire body motion. Elektra could dance, count to ten and smoke, while his dog companion Sparko,
could walk, stand on its hind legs and bark.
Applications
Automotive industry
Medical laboratories
Medecine
Nuclear energy
Agriculture
Spatial exploration
Underwater inspection
Customer service
Arts and entertainement
Automotive industry
One of the most important
partners in the development
of robotic technologies
.Welding robots
.Robustness and precision of
the assembly of pieces
.Found in painting rooms
.Used for places that are hard to reach

Robotics
[attachment=18400]
Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots.[3] Robotics is related to the sciences of electronics, engineering, mechanics, and software.
Etymology
The word robotics was derived from the word robot, which was introduced to the public by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots), which premiered in 1921.[5]
According to the Oxford English Dictionary, the word robotics was first used in print by Isaac Asimov, in his science fiction short story "Liar!", published in May 1941 in Astounding Science Fiction. Asimov was unaware that he was coining the term; since the science and technology of electrical devices is electronics, he assumed robotics already referred to the science and technology of robots. In some of Asimov's other works, he states that the first use of the word robotics was in his short story Runaround (Astounding Science Fiction, March 1942).[6][7] However, the word robotics appears in "Liar!"
A robotic leg powered by Air Muscles
Actuators are like the "muscles" of a robot, the parts which convert stored energy into movement. By far the most popular actuators are electric motors that spin a wheel or gear, and linear actuators that control industrial robots in factories. But there are some recent advances in alternative types of actuators, powered by electricity, chemicals, or compressed air:
Electric motors
The vast majority of robots use electric motors, often brushed and brushless DC motors in portable robots or AC motors in industrial robots and CNC machines.
Linear actuators
Various types of linear actuators move in and out instead of by spinning, particularly when very large forces are needed such as with industrial robotics. They are typically powered by compressed air (pneumatic actuator) or an oil (hydraulic actuator).
