The "hook" for this episode is the transposition of the Robot's "personality" into Dr. Smith and Dr. Smith's into the Robot. It does provide some amusing moments, and Jonathan Harris lip syncing the Robot's voice is very well done. That being said, it's rather hard to take the threat of the tiny mechanical men very seriously and the climactic "battle" between them and the Robinson's is ridiculous. The whole episode is obviously played for laughs. Joe Tata, who provides the voice of the "purple robot" would show up later as one of the space bikers in season three's "Collision of Planets".
