The inventions and innovations of Al-Jazari continue to influence modern engineering and robotics
Al-Jazari's invention of the crankshaft mechanism became fundamental to mechanical engineering, later powering steam engines and automobiles.
His automata could be programmed to perform different sequences, establishing the conceptual foundation for computer programming.
He invented the segmental gear, which converts rotary motion to linear motion — essential in countless modern machines.
His detailed manufacturing techniques and documentation methods set standards that influenced engineering for centuries.
"I have composed this book to benefit mankind and to assist in its well-being."
— Al-Jazari, 1206 AD
Father of Robotics • 1136–1206 AD
