Starting several steps back, robots has been around ever since the first conceptual 'robot' was concieved (450 BC), though it has only been put into practice and visual culture around 1495 by Leonardo da Vinci.
As for "Mecha", it would be in 1956; the date Tetsujin 28-go (Iron Man 28, also known as "Gigantor" in the American adaptation) made its debut.
