Episode cast overview:
Will Robinson (as Billy Mumy)


Will and the robot come upon a dead "robotoid." Will wants a crack at fixing it while the robot wants it left alone or destroyed. In fact, something quite strange is happening with the Robinson's robot: he's developing beyond his programming, becoming more than just machine. Thanks to Will's repairs, the robotoid comes to life, but while it quickly presents itself as a subservient boon to the Robinsons, it secretly softens them up for capture by its distant alien masters, who are on their way.

War of the Robots
13 November 2011 | by (United States) – See all my reviews

One of my personal favorite episodes as a youth, "War of the Robots" addresses perhaps a "human side" that seems to exist in Robot and his role in the Robinson family unit becomes far more important. Being a big fan of "Forbidden Planet" and Robby the Robot, it's no surprise this episode carries even more weight since the mechanized wonder has a special guest role in "War of the Robots". After fishing, Will Robinson (Bill Mumy) literally bumps into a disconnected "robotoid" (Robby the Robot), badly in disrepair and needing quite an overhaul. Will, against the wishes and warnings of Robot (who seems to know that this robotoid is indeed quite a threat to the lives of the Robinson party), decides to dedicate his spare time, a sort of side project, on repairing the robotoid, not knowing the results could be hazardous to his family. At first, the robotoid is of great service to the Robinson party, with Dr. Smith (Jonathan Harris) its most vocal supporter, but soon Will feels guilty and sad that he ever gave the machine new life, as Robot seems to become less important to them. With Smith always ridiculing Robot, telling him how he is no longer of any use (yeah, if you didn't like Smith before, his behavior here, wholly inappropriate and cruel, will not gain favor with you) and inferior to the robotoid, it decides to go away from the Jupiter site. But when the robotoid, actually a sinister servant of an alien race, shows its true side, taking the Robinson family hostage, Will will escape and try to get Robot to help him save his family (the alien race wish to use the Robinsons as test subjects, needing the robotoid to send them a homing signal to direct them to the planet). But can Robot save the Robinsons from a superior machine? It was a lot of fun revisiting this episode, and I consider it a strong entry in the up-and-down first season, particularly how Robot becomes a central figure in the plot and just the fact that we get plenty of Robby the Robot to enjoy. Having two robots in a "duel to the death" is rather neat, especially the cunning way Robot has to use his ingenuity in order to gain an advantage over a superior foe. But, most of all, seeing the show take a concentrated, concerted effort to advance the Robot beyond being just a machine that obeys orders/commands, was truly a pleasure for me personally. I don't think Dr. Smith has ever been as purely detestable as he is here…his treatment of Robot is despicable.
