Robots have captivated our imagination for centuries. From ancient myths to modern science fiction, the idea of intelligent machines has always fascinated us. But the concept of robots as we know them today didnt emerge until the 20th century.

The term robot was coined by Czech playwright Karel apek in his 1920 play R.U.R. (Rossums Universal Robots). The play depicted humanoid machines that were created to serve humans but eventually rebelled against their creators. This marked the beginning of our fascination with robots and their potential impact on society.

Fast forward to the 1950s, when the first industrial robots were introduced. These early robots were large, bulky machines designed to perform repetitive tasks in factories. They were controlled by analog circuits and lacked the sophistication of modern robots.

In the 1970s, the advent of microprocessors revolutionized the field of robotics. Suddenly, robots could be controlled by computer programs, making them more versatile and intelligent. This led to the development of robots capable of complex tasks, such as assembly line operations and space exploration.

Today, robots are everywhere. From robotic vacuum cleaners to autonomous cars, they have become an integral part of our daily lives. But what does it take to build your own robot? Lets find out!
