The world's largest walking robot is 51-feet long, weighs 11 tons and is powered by a 2.0-liter turbo diesel engine.

Oh, and it's a fire-breathing dragon.

The Guiness book of World Records 2014 has announced that 'Tradinno', built in Germany by Zollner Elektronik AG, is the biggest walking automaton in the known world.

Unlike a previous generation, which required four human operators, the Tradinno is fully robotic - and apparently "outshines all human actors", the company behind it says. But no, while it does have a pair of impressive 40-foot wings, it cannot fly.
