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.

Near the end of the episode, after the Robot says, "There is much we have to discuss," the Robot proceeds to move forward, out of frame. The tow cable attached to the rear of the Robot at ground level then becomes visible (the Robot was apparently towed backwards into frame, with the motion reversed in editing). See more

That is very good. We will need the homing signal to find you and the planet.
