Repair droid 7

Clockwork Woman was one of the Clockwork Droids operating on the SS Madame de Pompadour. The Tenth Doctor, Rose Tyler and Mickey Smith witnessed this droid reveal its presence to a young Lady Reinette through a time window aboard the ship. The Doctor crossed over to her time period and hosed it down with fire extinguisher gun. The Doctor had Reinette order it to answer all their questions, learning that it sought her as the final component to fix their damaged ship. However, she was not ready yet. Reinette ordered the Clockwork Droid to leave, and it complied for the time being. It later returned with the other droids to capture Reinette when she had recently turned thirty-seven, the same age of their ship. The droids thought this would make her compatible to repair it. However, the Doctor burst through their sealed time window on horseback, rescued Reinette and explained to the droids that they had become purposeless without a crew. All of them shut down forever.
