The Yonezawa Atomic Robot, introduced in 1968, was dubbed “Rotational Robot” for its distinctive top half rotation. It features a dual-face design, alternating between expressions of joy and anger during its mechanical movements. Powered by clockwork, it waddles with a pin walking mechanism operating its feet while its upper torso rotates back and forth. Sporting a colorful blue body adorned with red and yellow details, the Yonezawa Atomic Robot presents a striking visual aesthetic reminiscent of early vintage robots. Despite its seemingly retro design, this intriguing creation was manufactured and sold during the later stages of the golden era of tin toy robots.
