Yoshiya’s Planet Robot, while undeniably drawing inspiration from Robby the Robot,  distinguishes itself as a well-crafted and iconic creation in its own right. Operated by batteries through a remote control, the robot exhibits forward walking motion accompanied by blinking lights in its face.

In addition to the battery-operated version, there were also clockwork wind-up iterations of the Planet Robot. These wind-up variants were among the original Robby the Robot-type wind-ups produced by Yoshiya during the 1960s. Notably, there exist two versions of the robot featuring different hand materials: one in plastic and another in metal. There were also variations in the color of the face piece, with red being the most prevalent, while green and blue variants are considered more rare.
