Handbot

"Handbot" was a name coined by Amy Pond for the alien medical robots designed to assist residents of the Two Streams Facility, providing guidance and - if necessary - medicine (known as "kindnesses") to the patients.

The Handbots were approximately six feet tall, white and humanoid. Their hands were their most prominent features, serving many strange and mundane purposes. They use them to manipulate objects such as hypodermic needles, which they carried in their chest and head. With the aid of synthetic, organic skin that had been grafted onto their hands, they were used for sensory perception, "seeing" with their fingers. This form of sight was so potent that Handbots were even able to see the types of bacteria on a person. The eponymous hands also held anaesthetic transfer: one touch was all it took to send someone to sleep in moments.

Handbots were able to communicate to some degree with the patients, but lacked any kind of intelligence. If a person's reply to a Handbot did not match an "acceptable" reply, the statement would be rejected and the handbot would continue any course of action it deemed appropriate.

As previously mentioned, the Handbots were equipped with hypodermic needles and darts, which they used to administer their "kindnesses". The syringes were held in a chest compartment and given by hand. The darts were held inside the head (for feistier residents) and were shot at the resisting patients in what was known as the "secondary delivery system". Administration of medicine would usually be accompanied by a set dialogue: "Do not be alarmed. This is a kindness." They could be reprogrammed to be docile (as in the case of Rory); however Amy "disarmed" the robot, suggesting that even docile it could still be dangerous.

Inside the chest cavity, Handbots also held a "black box recorder", which would record any cause of termination. The Handbots could walk from place to place and jump between time streams, though they didn't teleport (despite the appearnace of the time jump.

Despite their many features, Handbots were less than formidable. Their sensors malfunctioned in the presence of Temporal Engines, they were slow moving and they were easily knocked out by blunt or sharp force. Furthermore, if the hands of Handbots touched it created a feedback loop which would knock them out. Only in great numbers did the Handbots pose a real threat. (DW: The Girl Who Waited)

Behind the scenes

 * Writer Tom MacRae has said that one of the scariest Doctor Who moments for him personally, was a scene in Terror of the Vervoids where Vervoids attack a man using deadly seed pods delivered from their hands. He speculated that the idea of hands being frightening may have subconsciously inclined him to create the Handbots.
