The Dragon is built from the Lego Wedo 2.0 educational kit. The movement of the dragon occurs due to the operation of a spur gear, which rotates a shaft that has protruding parts (cams). The cams act on the dragon and its wings, creating the effect of flight.
The set includes step-by-step building instructions and a example of program (in Lego Wedo 2.0 environment).
