Travel Machine

Davros developed a series of Travel Machines to house the mutated remains of his species, the Kaleds. This culminated in the Mark III Travel Machine, which he named Dalek. (TV: Genesis of the Daleks)

Development
By one account, Davros' chair was the Mark I Travel Machine, and his initial Dalek designs were the Mark IIs. (PROSE: The History of the Daleks) Another account had Davros present an early prototype machine before he had constructed his own advanced chair, after which he unveiled Dalek One. (PROSE: Davros Genesis) In any case, the Daleks were later perfected by Davros in the Mark III Travel Machine. (TV: Genesis of the Daleks)

By another account, Davros's Mark I Travel Machine was not his chair but a prototype casing of the first Dalek that he created, an experimental life support unit modeled after his own chair. Besides the transplanted Thal brain, it included a life support matrix, an optical stalk, feeding tubes and was activated by a power conduit with only 92% distribution. (AUDIO: Guilt) According to the Dalek Combat Training Manual, Davros abandoned this prototype and then his next model before settling upon the Mark III travel machine.
