Scooter 2000

Scooter 2000 was a psychopathic, power-hungry robot that believed solely in one thing - recreate the Scooter race and destroy all humans.

Biography
The Scooter 2000 robots were created to be servants with small signs of independence to make each machine unique and empathetic in some way. Most of them became dangerous, however, and they attempted to take control of humanity. This particular unit was the only known one to survive the purge, killing its creators. It crash landed on a field near Towell Farm, making the place its home.

After some time stranded, Scooter managed to lure the Doctor's TARDIS to a nearby field and beach. It used various entities it hired - Van, Basement, Bathroom and Television - to torture the Doctor before confronting the Time Lord himself. Despite his frustration, Scooter failed to communicate the seriousness of the situation and went straight to torturing the Doctor to near-death himself. He was distracted by the miniaturised TARDIS, however, and attempted to drain it of its power. Overwhelmed, Scooter malfunctioned and powered down before the Doctor used his sonic penny whistle to blow Scooter up, effectively ending the Scooter race. (Horror at Towell Farm)

Trivia

 * Scooter 2000 is considered to be a vintage and very rare item by today's standards. The unit used for the story is in good condition considering it spent most of its time either at a car boot sale, in an attic or in a barn.
 * It currently belongs to Daniel Welch, to be passed on to his son Ozzy when he becomes older.
 * Scooter's scenes were rushed because the family were leaving the farm as it was being filmed. Doherty stayed up all night in costume preparing for the scene, which would've been filmed at night had sleeping relatives not complained about noise.
