Characters and Cast

• Professor John Robinson (Guy Williams) is the commander of the Robinson family expedition. He is an expert in astrophysics and applied planetary geology as well as an ordained Minister.
• Doctor Maureen Robinson (June Lockhart) is John's wife, and a trained biochemist. She is the mother of their children, Judy, Penny and Will.
• Major Don West (Mark Goddard) is the pilot of the expedition's spacecraft, the Jupiter 2. Don is romantically interested in Judy, and inherently distrustful of Dr Smith.
• Judy Robinson (Marta Kristen), Penny Robinson (Angela Cartwright) and Will Robinson (Bill Mumy) are the three children in the expedition. Of the three, Will is the most noteworthy - he is the youngest, brightest and a particular friend of Dr. Smith and the Robot.
• Doctor Zachary Smith (Jonathan Harris), ostensibly the mission's doctor of environmental and intergalactic psychology (but in fact an enemy agent) is in charge of preparing the Robinson party. His attempt to sabotage the mission saw him stranded aboard as a "reluctant stowaway", from which the pilot episode takes its title.
• The Robot, a Model B-9 Environmental-Control Robot, which had no given name. However, in the third-season episode entitled "The Time Merchant," it was shown in its packing crate, and the crate was labeled ONE General Utility Non-Theorizing Environmental ROBOT, with the G, U, N, T, and E, and all letters in ROBOT in red capital letters, while all the other letters were black; some have suggested that this was supposed to convey the acronym GUNTER; see these screen shots. The Robot was designed by Robert Kinoshita, and performed by Bob May in a suit built by Bob Stewart, with voice by Dick Tufeld, who was also the series' narrator.
