Measuring Equipment

Measuring Equipment The electronic measuring equipment used to create stimuli and measure the performance of the devices under test (DUT for its acronym in English) .The measurement of mechanical quantities, thermal, electrical and chemical is performed using devices called sensors and transducers. The sensor is sensitive to changes in the measured variable, as a temperature, a position or a chemical concentration. The transducer converts...

Electronic Circuits

Electronic Circuits A circuit is a mains (interconnection of two or more components, such as resistors, inductors, capacitors, power switches and semiconductor) that contains at least one closed path. A linear circuit, consisting of sources, linear components (resistors, capacitors, inductors) and linear distribution elements (transmission lines or cables), has the property of linear superposition. They are also easier to analyze, using methods...

Resistance

Resistance It is the physical property by which all materials tend to resist the flow of current. The unit of this parameter is the ohm (Ω). Not to be confused with the resistor component. Conversely property is electrical conductance. ...

Electric Current

Also called intensity, is the flow of electrons through a conductor or semiconductor in a sense. The unit of measurement of this parameter is the ampere (A). As there are continuous or alternating voltages, currents can also be direct or alternating, depending on the voltage used to generate these current flows. ...

Tension

Tension It is the potential difference generated between the ends of a component or electrical device. We can also say that energy is able to set in motion the free electrons in a conductor or semiconductor. The unit of this parameter is the volt (V). There are two types of stress: the continuous and alternating. DC voltage (VDC) It's one that has a definite polarity as that provided by batteries and power supplies. AC...

Electronic Signals

Electronic Signals It is the representation of a material physical phenomenon or state through an established relationship; the inputs and outputs of an electronic system will be variable signals. In electronics working with variables that take the form of voltage or current commonly these can be called signals. Primarily signals can be of two types: Variable analog-they are those that can take an infinite number of values ​​between...

Classification of robots

According to the chronology Which then arises is the most common classification: 1st Generation. Manipulators. They are multifunctional mechanical systems with a single control system, either manually, sequence or fixed sequence. 2nd Generation. Robots learning. Repeating a sequence of movements that has been previously performed by a human operator. The way is through a mechanical device. The operator performs the required movements...

History

The history of robotics is linked to the construction of "artifacts" that tried to materialize the desire to create human beings in His likeness and that descargasen work. The Spanish engineer Leonardo Torres Quevedo (who built the first remote control for your car by wireless telegraphy, the automatic chess player, the first air shuttle and many other mills) coined the term "automatic" in relation to the theory of automation traditionally associated...

Robotics

Robotics is the branch of mechanical engineering, electrical engineering, electronic engineering and computer science that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics combines various disciplines such as: mechanics, electronics, computer science, artificial intelligence, control engineering and physics. Other important areas in robotics are algebra, programmable robots,...

Microprocessors

In 1969, Ted Hoff conceived the commercial microprocessor at Intel and thus ignited the development of the personal computer. Hoff's invention was part of an order by a Japanese company for a desktop programmable electronic calculator, which Hoff wanted to build as cheaply as possible. The first realization of the microprocessor was the Intel 4004, a 4-bit processor, in 1969, but only in 1973 did the Intel 8080, an 8-bit processor, make the building...

Computers

A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated...

Radar and radio location

During World War II many efforts were expended in the electronic location of enemy targets and aircraft. These included radio beam guidance of bombers, electronic counter measures, early radar systems etc. During this time very little if any effort was expended on consumer electronics developments. ...

Television

In 1928 Philo Farnsworth made the first public demonstration of a purely electronic television. During the 1930s several countries began broadcasting, and after World War II it spread to millions of receivers, eventually worldwide. Ever since then, electronics have been fully present in television devices. Modern televisions and video displays have evolved from bulky electron tube technology to use more compact devices, such as plasma and LCD...

Wireless telegraphy and radio

Some of the devices which would enable wireless telegraphy were invented before 1900. These include the spark-gap transmitter and the coherer with early demonstrations and published findings by David Edward Hughes (1880) and Heinrich Rudolf Hertz (1887 to 1890) and further additions to the field by Édouard Branly, Nikola Tesla, Oliver Lodge, Jagadish Chandra Bose, and Ferdinand Braun. In 1896, Guglielmo Marconi went on to develop a practical and...

History

The history of electronic engineering is a long one. Chambers Twentieth Century Dictionary (1972) defines electronics as "The science and technology of the conduction of electricity in a vacuum, a gas, or a semiconductor, and devices based thereon". Electronic engineering as a profession sprang from technological improvements in the telegraph industry during the late 19th century and in the radio and telephone industries during the early 20th...

Engineering Components

Component engineering is an engineering discipline primarily used to ensure the availability of suitable components required to manufacture a larger product. The term combines two ideas: A component—a smaller, self-contained part of a larger entity Engineering—the discipline and profession of applying science to implement some functional design Those who practice this discipline are called component engineers. Component engineers...

Telecommunications

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies. Early means of communicating...

Industrial Process Control

Process control is an engineering discipline that deals with architectures, mechanisms and algorithms for maintaining the output of a specific process within a desired range. For instance, the temperature of a chemical reactor may be controlled to maintain a consistent product output. Process control is extensively used in industry and enables mass production of consistent products from continuously operated processes such as oil refining, paper...

Computers And Digital Electronic

In computer science, a digital electronic computer is a computer machine which is both an electronic computer and a digital computer. Examples of a digital electronic computers include the IBM PC, the Apple Macintosh as well as modern smartphones. When computers that were both digital and electronic appeared, they displaced almost all other kinds of computers, but computation has historically been performed in various non-digital and non-electronic...
