Kingston Grammar School was invaded by robots on September 16, as TV star Jason Bradbury showed off a series of wacky automatons to delighted pupils.

Mr Bradbury had his rocket-powered car convincingly beaten by children from the school on the Gadget Show in 2007, and was keen to visit the design department which had inspired the winning creation.

The presenter also spoke to pupils about his first novel, Dot.Robot, before signing copies and giving out clues to a hidden website accessible once the book’s code is cracked.
