Get to know the robots

robot definition

A robot is a machine designed through an engineering system that makes it work as an alternative to human labor, despite its appearance that is not similar to the appearance of humans, but it is able to perform the required function in the way that humans do.
The robots come in different sizes, some of them are very small the size of a coin, and some are large, their size is larger than the size of a car. Some of them are able to perform surgeries inside the human body to help doctors, others work in restaurants to prepare pancakes, and some can land on Mars.
As a result of this great diversity in the sizes, designs, and capabilities of robots, it was difficult to reach a definition for it, and robotics scientists had different definitions of the robot, which led to a general concept of the robot, which is that it is a machine that operates independently by sensing its surroundings and performing calculations to arrive at certain actions. It makes decisions and implements them in the real world.

What is the field of robotics

"Robotics" has become a field of study that is taught today in universities, and it is related to science, engineering, and technology together. This is because it combines and blends scientific subjects, including mathematics, science, and engineering disciplines such as mechanical engineering, for example.
Robotics specializes in designing, building, preparing and programming robots, and robots have appeared with the purpose of being a substitute for humans in some tasks, where they can be used a lot, but today, the use of robots is limited to dangerous work that can be dangerous to humans, such as detection operations. about mines, or it is also used to detect and survey environments in which humans cannot live, such as outer space and in factories, and the shape of the robot can vary from one to another, and there are many forms for it, but its familiar external appearance looks similar to the human form so that it can walk Speaking, doing many things that people do.
Robots are also considered one of the most important parts of the teaching process, especially in teaching basic science subjects, because they are used as an educational tool in science, engineering, and mathematics. It is expected that the robot will replace the human in many jobs and matters, but the need for a human supervisor is still required, as the human is the one who prepares it, programmes it, shows it and monitors its performance.

History of Android

Here are the stages of the evolution of robotics:
Human statues were used in 3000 BC to ring the bells of Egyptian water clocks.
Architus tarmactum invented a flying pigeon made of wood.
Egypt built hydraulically operated statues in the second century BC.
Petronius Arbiter created a doll that could move like humans in the first century AD.
In 1557, Giovanni Torriani invented a wooden robot that brought bread from the shop daily and brought it to the Emperor.
A large number of genius robots were invented in the eighteenth century and have reached their peak, but they were not practical.
Many types of creative robots were invented in the nineteenth century, such as: Edison's invention of a doll that can talk, and the Canadians' invention of a steam-powered robot.
The first modern robots were invented by George C. Devol, who is from Louisville - Kentucky, and that was in the early fifties of the twentieth century. Produced, but it didn't work.
George Devol gave a patent to engineer Joseph Engelberger in the late sixties of the twentieth century.
Charles Rosen, with the help of a research team at Stanford Research Institute, developed in 1958 AD a robot called "Shakey", and it was a very advanced robot from the robot "Unimate". On responding to his surroundings and environment, and even the surroundings unfamiliar to him, and his ability to walk around and notice things with his eyes.

Android components
The human body is made up of five main components; The external body structure, the muscular system to move the body structure, the sensory apparatus that senses the environment and the surroundings, a source of energy to activate the muscles and organs of the body, and the brain that processes information and sends it to the body’s systems, and since robots are machines that simulate human behavior, they consist of the same components and are as follows:
Effectors: Its structure consists of effectors such as arms, legs, hands, and feet.
Sensors: They are the parts that resemble a sensory device, which detect things around them, such as heat, light, etc., and then convert the information collected by the sensors into codes that can be read by computers.
Computer: The computer in the robot works like the brain, and it controls the movement of the robot through the instructions inside it, which are called algorithms.
Equipment: The mechanical tools and structures that make up the robot.
Android uses
Robots are used in many different uses and in various areas of daily life, and their uses are as follows:
Restaurants: Japan is known as the most used robots in restaurants in the world, as it uses them for cooking such as cooking sushi, cutting vegetables, producing food, growing rice and caring for crops, and in preparing coffee, as well as using them as receptionists and cleaners, and some are used as waiters in restaurants to serve drinks .
Assisting the elderly in living life: Robots are used in nursing homes for the elderly, as the Korean robot can carry a human weighing up to 100 kilograms, and the elderly can easily control the chair using a joystick, and robots help the elderly get up from bed, and they can take the place of Friends and relieve the feeling of loneliness in the elderly.
Combating crime: The police use robots to enter buildings where armed criminals are located, which helps locate them, and they use them to check car bombs, and in cases where hostages are present.
Medicine: Robots are used in medicine to perform complex surgeries. Doctors control through cameras and robotic arms perform surgeries with high accuracy. They are also used to dispense medicines to patients, and fill the pharmacy with medicines by programming them to move through elevators and reach any floor in the hospital.
Education: The Early Childhood Education Center in San Diego, California uses robots to act as a teacher's assistant to teach children to speak and sing, and to help children improve their thinking and start doing things from an early age.
What is robotics?
Robotics is a sector that includes several disciplines, including science and engineering. These disciplines are concerned with studying the design, construction, and use of mechanical robots. It is a meeting point between science and engineering and the technology that produces robots.
As it is a modern artificial science concerned with the study of programming, robotics technologies are rapidly advancing to keep pace with current science visions to find safer intellectual foundations capable of achieving more reliable and safe capabilities and results that can go deeper into society.
