Meet the World's Largest Four-Legged, Fire-Breathing, Walking (Robot) Dragon

Written by: Cat McClintock

Dragons are real. At least there’s one prowling the stage every summer in Furth im Wald, Germany that looks real. Like, stop-you-in-your-tracks real.

 It also has a name: Tradinno (a play on the words tradition and innovation).

 At 50-feet long and 30-feet tall, this giant, motorized, fire-breathing robotic dragon weighs 11 tons, holds more than two gallons of (fake) blood in its veins, and is the biggest walking robot in the world. It moves on four scaly legs and has its own vehicle for longer trips. The walking robot is powered by a 140-horsepower 2.0-liter turbo diesel engine and (well, duh) overshadows all the actors on the stage. 

Its developer, Zollner Elektronik AG, wanted to design and engineer a dragon on an unprecedented scale, enabled by wireless remote control, that could be used outdoors as part of one of Germany’s oldest folk plays. Zollner’s unique transport vehicle lets the robot dragon easily move from points A to B while frightening little children along its merry way.

The Software behind the Design: Creo

At the beginning of the project, detailed calculations, numerous simulations, and dynamic motion sequences were performed. Simulations included working life, durability and temperature resistance, as well as comprehensive tolerance analyses to support the developer’s calculations. These design challenges were met by using PTC CAD software for development of the dragon. 


Note. Tradinno was designed to hold almost three gallon of liquid gas and spit fire on cue. In case the size of the dragon doesn’t catch your attention, the fire certainly will.
