CHIEF ROBOTMAN - YOSHIYA - JAPAN

Tin battery operated robot. Advances with bump and go mystery action as his head turns, eyes light and antennas spin. KO skirt.

This robot appeared in two color versions: grey and light blue. In addition the arms are usually tin, but plastic arm versions exist. The fact that it had a long production run may account for the variations, particularly the introduction of the plastic arms. The metallic blue version of the Chief Robot Man can't automatically be called a Radical Robot, though sellers like the added rarity of the name.

The first sighting of the robot is in Alden's; Lazarus and Newberry’s catalog for 1962. This confirms that it is the first of the Yoshiya family of skirted robots. It has been reproduced. The fins on the bellybutton of an original run from top to bottom. On the repro version they run from side to side.
