This 1957 build robot is controlled by a remote that takes 3 big battaries, the robot itself takes also 3 big battaries. The robot can be started with a single push on the red button of the remote and it makes the robot go in several sequenses: forward, left, right, stop with swinging arms, "clicking" contact in the chestplate, light and of course his ear spins. On the left of his "ear" goes a big antenna to receive the commands given by the remote. The remote itself has also a pretty big antenna to sent out the commands. The technique used in this robot for remote control is very old and therefore complicated and is based on the basics of sending and receiving.
