Ugears Wooden 3-D Puzzle – Tyrannosaurus Rex

Ugears launches its dinosaur automaton collection with the most fearsome predator to ever walk the earth: the Tyrannosaurus Rex. This mechanical DIY wooden model of a walking tyrannosaur is driven by a metal spring, which transmits power through a reduced gear, turning the axle that drives the legs. A clever system of links and connections allows this king of dinosaurs to walk on its own two feet—the first bipedal walker in the Ugears collection! An eccentric gear sets the tail swaying in synchronous motion with the legs, helping the dinosaur keep its balance and not fall to the side, just as in nature.
