 History of Robotics  A Brief History of Robotics (in Simple Words) Robotics has a long history that goes back thousands of years, starting with simple machines and leading to today’s intelligent robots. Early Ideas and Machines Ancient times (around 350 BCE – 1200 CE): People built early mechanical devices called automata. For example, Archytas made a steam-powered wooden bird, and Al-Jazari created machines that could play music and help people wash their hands.            Renaissance (1495): Leonardo da Vinci designed a “mechanical knight” that could move its arms, sit down, and open its mouth.                                  Industrial Revolution (1804): Joseph-Marie Jacquard invented the Jacquard Loom. It used punch cards to control patterns, which was an early form of programming.                  ...
