What is Robotics ?

Technology’s field of robotics is concerned with the creation, maintenance, use, and application of Robots. Robots are programmable robots that may be directed to carry out different activities automatically, either independently or under the direction of a human. To build robots that can perceive, understand, and act in the physical world, robotics incorporates a number of disciplines, including mechanical engineering, electrical engineering, computer science, and artificial intelligence. Manufacturing, healthcare, agriculture, space exploration, and many other fields have various uses for robotics.

History of Robotics

Robotics has a long history, going back to antiquity, when inventors and thinkers conjured up robots that could carry out human-like functions. On the other hand, the first real robot as we know it today was developed in the 20th century.

The term “robot” was originally used in the play “R.U.R.” by Czech playwright Karel apek in 1921. In the play, humanoid machines that could do manual labour eventually rebelled against the people who had built them.

Researchers started creating robots for industrial uses, particularly in manufacturing, in the 1940s and 1950s. George Devol and Joseph Engelberger created the Unimate, the first industrial robot, in 1954. It was put into operation in 1961 at a GM plant in New Jersey to lift and stack massive things.

The study of robotics advanced into fields like military, medical, and space applications throughout the ensuing decades. Researchers created robots that could help with surgical procedures and explore space in the 1960s and 1970s. Robotics research in the 1980s and 1990s concentrated on creating autonomous robots that could move around and communicate with their surroundings.

Autonomous vehicles, drones, and personal assistants are just a few examples of how robotics is now developing and expanding into new fields. Robotics is a fast expanding field that has the potential to significantly improve human life and revolutionise many industries.

Ancient Times: Early Concepts of Robotics

It has been a long-standing dream of engineers to build machines that can carry out activities that humans do. The Chinese inventors of the 4th century BC developed humanoid figures that were propelled by pulleys and levers, while the Greek inventor Hephaestus created mechanical servants that assisted him in his work.

The Medieval Ages saw the development of automata, or mechanical objects with the ability to move independently. Albertus Magnus, a monk, built a mechanical bird that could sing and flap its wings as one instance.

Leonardo da Vinci made designs of different mechanical devices during the Renaissance, including robots that could walk, speak, and write.

A youngster who could write and a musician who could play the flute were two of the mechanical figures made by Swiss watchmaker Pierre Jaquet-Droz in the 18th century.

Charles Babbage and Ada Lovelace created the groundwork for modern computing in the 19th century, which eventually paved the way for the creation of robots driven by electronic circuits and digital code.

Although many of these early robotics ideas were fantastical and unworkable, they helped pave the path for contemporary robotics by showing how humans wanted to build machines that could carry out jobs and behave like humans.

Industrial Revolution: Automata and the Rise of Robotics

Manufacturing mechanisation and automation increased during the Industrial Revolution of the 19th century, which paved the way for the creation of machines that could complete jobs faster than people could. During this time, automata—mechanical toys that could move and carry out basic tasks—also began to appear.

French inventor Jacques de Vaucanson produced automata in the middle of the 1800s, including a mechanical duck that could eat and digest food and a flute player who could play 12 different songs.

Thomas Edison and Nikola Tesla started experimenting with electrical power in the late 1800s, laying the groundwork for the creation of electric motors and other electrical components needed in robotics.

The first industrial robots intended for use in production appeared in the early 1900s. The term “robot” was first used by Czech author Karel Čapek in his play “R.U.R.” (Rossum’s Universal Robots), which portrayed humanoid machines designed to carry out manual labour.

George Devol created the first programmable robot in 1937, which was used to operate machinery in a factory. Devol later created the Unimate, the first industrial robot, which was put into operation in a General Motors plant in 1961 to carry out activities like welding and painting.

The use of robotics in industry has enhanced production and efficiency while enabling the completion of hazardous or laborious activities that were previously completed by human workers. Robots now are capable of a wide range of jobs, from assembly and packing to exploration and space travel, and they continue to transform manufacturing and other industries.

Tesla’s remote-controlled boat and radio-controlled devices

Nikola Tesla, an inventor, explored remote control technologies in the early 1900s and even created a remote-controlled watercraft. Tesla showed the boat’s capabilities by guiding it around a pool in Madison Square Garden in New York City in 1898. The boat was propelled by radio waves.

The earliest instance of radio-controlled technology, which subsequently gave rise to radio-controlled aircraft and other equipment, was demonstrated by Tesla’s boat. Tesla also created additional radio-controlled gadgets, such as a wirelessly controllable tiny automobile.

Tesla’s pioneering work with remote control technology served as the basis for the advancement of contemporary robotics. Remote control technology paved the way for the creation of autonomous, wireless devices that could complete tasks without the need for direct human input.

From model aeroplanes and hobby drones to military drones and robotic vehicles used for exploration and scientific study, radio-controlled devices are used in a broad variety of applications today. Technological developments like GPS navigation and artificial intelligence are enabling robots to carry out more and more difficult tasks on their own.

The 20th Century: The Golden Age of Robotics

The fast advancement and wide-spread use of robotics during the 20th century helped to bring in what is frequently referred to as the “golden age” of robotics. During this time, robotics progressed from primitive, single-purpose machines to sophisticated, multi-purpose robots that can carry out a variety of activities.

Robots began to be employed in manufacturing in the 1950s and 1960s to complete activities including welding, painting, and assembly line labour. George Devol and Joseph Engelberger established Unimation, the first robotics firm in history, in 1956. Unimate later created the Unimate robot, which became the first industrial robot used in manufacturing.

NASA used robotic probes to investigate the Moon and other planets during the 1970s and 1980s, marking the beginning of the development of robotics in space exploration. The first autonomous robots, able to complete tasks without human assistance, were also created at this time.

Robotics was widely used in the 1990s for a variety of purposes, from medical and surgical robots to military and defence robots. At this time, the first humanoid robots were created, such as Honda’s ASIMO and Sony’s QRIO.

Robotics is still developing and finding new uses in the twenty-first century, including social robots that can interact with people in a variety of contexts. Robotics is also used in areas including transportation, agriculture, and environmental monitoring, and it has the potential to completely transform a variety of markets and facets of daily life.
