Ugears adds a new beast to its dinosaur automaton collection with the Triceratops ("three-horned face"), a dynamic, mechanical DIY wooden model of the dominant herbivore of the late Cretaceous period. Like our Tyrannosaurus Rex model, the Triceratops is driven by a metal spring that transmits power through a reduction gear, turning the axle that drives the four legs. An eccentric gear sets the tail swaying in synchronous motion with the legs, helping the dinosaur walk smoothly, just as in nature.
