Gadget The Robot has gone on display at the Doctor Who Exhibition in Coventry in the West Midlands.
The exhibition, which has an extended run until January, now features the Robot along with other props and costumes from The Waters of Mars including The Water Zombie and the costume of Captain Adelaide Brooks.
Visitors to the exhibition at Coventry Transport Museum, can also see Bessie, the Third Doctor's yellow roadster car and Jon Pertwee's costume.
Chief executive of the museum, Gary Hall, said: "The Doctor Who exhibition has been a big hit, with visitors coming again and again to see the exhibition. Getting new props for Christmas provides our visitors with a fantastic opportunity to visit the exhibition during Christmas holidays. We would urge people not to miss out on seeing the fantastic new props and costumes and posing next to Bessie for a photograph."
Note that although there is a charge to see the Doctor Who Exhibition, entry to the general museum is free. Visitors can see Bessie for nothing.
