Cyber-Planner

Cyber-Planners were used by the Cybermen to create and direct battle plans and strategies.

Physical Characteristics
The Cyber-planner were approximately six feet tall and consists of a framework of metal and transparent tubes with a number of lights and a rotating head section, completely immobile and often concealed in a secure place.

The shape of Cyber-Planners differed between the 20th (DW: The Invasion) and 21st centuries, the later "head" section having a more a bulbous, egg-like appearance (DW: The Wheel in Space)

Functions
The Cyber-Planner gathered data from a large variety of sources. It could scan local media transmissions and can even channel data from certain human subjects. It used this data to formulate strategies and makes desicions based upon probability of success.

The Cyber-Planner has no defensive capabilities and can be destroyed by emotions created by the cerebration mentor, suggesting that they had organic components.

History
It is not known when the first Cyber-Planner was built, although the fact that, in the late 20th century, one had knowledge of the Doctor's visit to Planet 14 might suggest certainly before that encounter.

Years before, Tobias Vaughn had a Cyber-Planner installed in his office at International Electromatics where acted as a communications channel between Vaughn and the Cybermen. (DW: The Invasion)

The Doctor found another Cyber-Planner at work on Earth during a movie shoot of a film based on the Tobias Vaughn incident. (ST: Scientific Adviser)

In the 21st century, Cybermen deferred to a Cyber-Planner while advancing their plan to take Space Station W3. (DW: The Wheel in Space)
