The Robinsons in suspended animation tubes, in unaired pilot, No Place to Hide. General Utility Non-theorizing Environmental Control Robot, Model B9 (Science Fiction Museum and Hall of Fame, Seattle)The crew had a variety of methods of transportation. First, there was the two-deck, nuclear powered Jupiter-2 flying saucer spacecraft. (In the original pilot, the ship was named "Gemini 12", and consisted of a single deck.) On the lower level were the "atomic motors" (which use "deutronium" for fuel), living quarters, galley, laboratory, and the robot's compartment. On the upper level were the guidance control system and suspended animation "freezing tubes" needed for interstellar travel. The two levels were connected by an electronic elevator and a fixed ladder. The Jupiter-2 explicitly had artificial gravity.

Second, the "Pod" a small spacecraft first shown in the third and final season and modeled on the Apollo Lunar Module was used to travel from its bay in the Jupiter 2 to destinations either on land or in space. The Pod apparently had artificial gravity too.

Third, the "Chariot" was an amphibious tracked vehicle the crew used when they were on a planet. Since most body panels were clear including the roof and its dome-shaped "gun hatch" the Chariot had retractable mylar curtains for privacy. Both a roof rack for luggage and roof mounted solar batteries were accessible by exterior fixed ladders on either side of the vehicle. The roof also had a swivel-mounted, interior controllable spot light near each front corner. The Chariot had six bucket seats (three rows of two seats) for passengers. The interior featured a seismograph, a scanner with infrared capability, a radio transceiver, a public address system, and a rifle rack that held four laser rifles vertically against the inside of the left rear body panel.

Fourth and last, the then exciting new invention called a jetpack was used occasionally by Prof. Robinson or Major West.

One of the most vital pieces of equipment was their environmental control robot B-9. The Robot ran air and soil tests, was extremely strong, able to discharge strong electrostatic charges from his claws, could detect threats with his scanner, produce a defensive smoke screen, produce exact duplicates of small objects like a pair of gloves, and could even detect faint smells (in "One of Our Dogs is Missing"). He could both understand speech as well as speak. In episode 8 ("Invaders From The Fifth Dimension") the Robot claims the ability to read human minds by translating emitted thought waves back into words.

For self-defense, the crew of the Jupiter-2 (including Will Robinson on occasion against his parents' wishes) had an armory of laser guns at their disposal, both long guns and handguns, which they openly carried. The crew employed a force field around the Jupiter-2 for protection while on alien planets.

For communication, the crew used small transceivers to communicate with each other when away from the ship. On one occasion, Will improvised several rockoons in an attempt to send an interstellar "message in a bottle" distress signal.

The Jupiter-2 had advanced technology that simplified or did away with mundane tasks. The "auto-matic laundry" took seconds to clean, fold, and package clothes in plastic bags. Similarly the "dishwasher" would clean, wash, and dry dishes in just seconds. The ship had no light bulbs. Maureen said the lights were "transistorized", perhaps meaning they were electroluminescent or built from arrays of light emitting diodes. "Protein pills" (a complete nutritional emergency substitute for whole foods) were featured in "The Hungry Sea" (air date: Oct 31, 1965) and "The Space Trader" (air date: March 9, 1966). In this, Lost in Space was ahead of NASA and Pillsbury, which later developed "Space Food Sticks".[3] Silver reflective space blankets, a then new invention developed by NASA in 1964, were used in "The Hungry Sea" (air date: Oct 13, 1965) and "Attack of the Monster Plants" (air date: Dec 15, 1965). The crew's spacesuits were made with mylar and had Velcro fasteners, both of which were first used in NASA spacesuits in the early 1960s.

On the other hand, sound and voice recording was less advanced, for example, using reel-to-reel tape recorders, and Prof. Robinson often put pen to paper to write journal entries in early episodes.
