Unwilling to land before investigating conditions on the planet, John decides to make the descent using parajets, arm-mounted rockets that will take him safely down to the planet's surface for exploration. When he is nearing the planet, John's parajets begin to malfunction and all communication with the Jupiter 2 is lost. Smith seizes the opportunity to employ The Robot to force Don and Maureen to abandon John and return the ship to Earth immediately. Seemingly complying with Smith's order, Don suddenly throws the ship into a violent manoeuvre that allows him to restrain Smith long enough to force him to order the Robot to leave the control deck. After placing Dr. Smith in suspended animation, Don and Maureen take the ship down to the planet. The Jupiter 2 crashes on the planet due to an earlier act of sabotage by Dr. Smith of the ship's rockets. The Robot is sent out to analyze the environment before anyone is allowed to leave the ship to look for John. Although only marginally habitable, the planet will sustain life. The Robinsons soon assemble the chariot and begin to search for John. As they search, they come across a small ape-like creature. Penny impetuously asks if she may keep it, but her mother angrily refuses, preoccupied with finding her husband. When she realizes the devastating effects of her words, though, she relents, and Penny names the creature Debbie. Back at the ship, the Robot frees Dr. Smith from suspended animation, having been programmed to monitor his well-being at hourly intervals. The search party eventually find John trapped in a chasm, tormented by electrical discharges that have rendered him almost completely helpless and destroyed his radio. Upon reaching the Jupiter 2, they are shocked to find Dr. Smith revived; they seem to expect a confrontation, but Dr. Smith is strangely conciliatory and apologetic. Soon after, Dr. Smith issues new orders to the Robot. It is to eliminate all members of the party except Major West, who will be needed to pilot the ship. The Robot is to use every opportunity to find the individual Robinsons alone and kill them with no witnesses so that their deaths may be attributed to adverse reactions to unknown elements in the planet's atmosphere. Against his father's orders Will goes to the chariot that night to make repairs. While Will is at work, the Robot follows him to carry out Dr. Smith's order. Ignoring Will's orders to stop, it continues to approach him while discharging powerful electrical bolts from its claws. Source Lostinspacefandom.com
