Al-Jazari and the First Programmable Humanoid Robot
Before Da Vinci there was Al-Jazari - the Engineering genius of the Islamic world in the Middle Ages. He designed and built a number of automatas including the first programmable humanoid robot
constructed in 1206
The previous claim for the world’s oldest programmable automata is for a machine built by Leonardo da Vinci in 1478.
