When were the mechanical devices built?

Mechanical devices have been built since ancient times, with significant examples dating back to around 300 BC. Notable inventions include the Antikythera mechanism from ancient Greece, which was created around 150-100 BC, and various water clocks and simple machines like levers and pulleys. The development of more complex mechanical devices continued through the Middle Ages and the Renaissance, culminating in innovations such as clockwork mechanisms in the 14th century and later advancements during the Industrial Revolution in the 18th and 19th centuries.
