The 3rd century BC text of the Liezi describes an encounter between King Mu of Zhou and an 'artificer' known as Yan Shi, who presented the king with a life-size automaton. The 'figure' was described as able to walk, pose and sing, and when dismantled was observed to consist of anatomically accurate organs.
The 5th century BC Mohist philosopher Mozi and his contemporary Lu Ban are attributed with the invention of artificial wooden birds (ma yuan) that could successfully fly in the Han Fei Zi and in 1066, the Chinese inventor Su Song built a water clock in the form of a tower which featured mechanical figurines which chimed the hours.
In 1515, Leonardo da Vinci designed and built the Automata Lion, one of the earliest described animatrons. The mechanical lion was presented by Giuliano de’ Medici of Florence to Francois I, King of France as a symbol of an alliance between France and Florence. The Automata Lion was rebuilt in 2009 according to contemporary descriptions and da Vinci's own drawings of the mechanism. Prior to this, da Vinci had designed and exhibited a mechanical knight at a celebration hosted by Ludovico Sforza at the court of Milan in 1495. The 'robot' was capable of standing, sitting, opening its visor and moving its arms. The drawings were rediscovered in the 1950s and a functional replica was later built.
