A sudden storm destroys the Robinson's food supply, artificially created by an unscrupulous space trader with an ulterior motive. He thereafter makes himself known and uses food to lure them into trading, but Prof. Robinson stands fast. Stuck with limited rations (practically nothing more than a few protein pills and a swig of water), only Dr. Smith among the Robinson party grumbles. The trader soon has Smith doing business, at first trading the robot for food, then for Smith himself to trade the robot back. By verbal agreement, the trader intimates he wouldn't collect Smith for another 200 years, but verbal indications aren't binding, and under the fine print of their signed contract, the trader exercises a clause whereby he can collect - now! (his intent all along). Written by

The Space Trader's space ship is also Alonzo P. Tucker's space ship from The Sky Pirate. See more
The Space Trader launches the first storm (in the opening scenes) and everyone is forced to go inside the spaceship. As the robot is going up the ramp, its forward progress slows and then it lunges forward. As it does, the robot's front treads lift off the ramp and its weight is way behind its base. Clearly the robot fell backwards while filming this scene. Played back slowly, you can see Angela Cartwright reach out to grab the robot as it starts to fall. See more
The Space Trader
[to his dog
Imagine that! He loves a robot like a brother, and yet he was prepared to trade him for a little bit of food. Heh-heh-heh-heh-heh. It would seem that I have found my Earthling - Dr. Smith.
