NON STOP ROBOT aka LAVENDER ROBOT - MASUDAYA - JAPAN

Non Stop Robot, more usually known as the Lavender Robot: the body has, as the nickname suggests, a basic lavender colouring with copious inset panels carrying abstract machinery detailing. Bump and go mystery action. Gang of Five.

Slight variations are known. There is a "high switch" and, less frequently a "low switch" version. This refers to the location of the on-off switch. High is just below the chest panel. Low is well below the circle. See below.

It is also believed that there is a version with grey litho insert panels rather than the usual lavender color. Some argue that this is the result of fading, but the concensus is that it is a variation.
