Dr Who K-9 :
K-9 is a robotic dog who has appeared in the Dr Who programmes over the years and who servers the Doctor on his travels. The most distinctive word K9 uses is ‘affirmative master’ closely followed by the phrase ‘insufficient data’.
The mechanics of K-9 included rotating ear-probes, telescopic 'eye' probe, extendable nose concealing a powerful laser weapon, flashing lights on the top and the 'eye' panel, waggling tail antennae, and ticker-tape tongue.
The head could also move up and down.
The shell was painted in gold/grey metallic. Around K9's neck was a tartan collar, from which hung a silver disk
