This is Maria, who you may recognise from the 1927 sci-fi classic Metropolis. I met her at the weekend, and if you pop along to the National Museum of Scotland in Edinburgh you can meet her too. She’s one of the attractions in the museum’s robots exhibition, which is great fun â€“ there’s a Terminator! â€“ and features some more practical, modern bots too. Â£10 for grown-ups, kids go free.
