UGears Tyrannosaurus Rex Mechanical Model

 OVERVIEW: 

Assemble me. Bring a fearsome ancient apex predator to life!

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 that 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 synchronized motion with the legs, helping the dinosaur maintain balance, just as in nature.

Up to thirteen meters in length and weighing nine metric tonnes, tyrannosaurs had the largest teeth of any carnivorous dinosaur, capable of tearing flesh and crunching bone. They possessed highly developed senses of smell and incredibly acute eyesight, making them the apex predators of the late Cretaceous period. This UGears model captures that prehistoric power and motion in intricate mechanical detail.

To operate, remove the hidden key from the tail, wind the mechanism half a dozen turns, place the model on a flat surface, flip the switch to “on,” and release. The Tyrannosaurus walks forward on its own, its tail swinging and jaws snapping open and shut with every step.

The UGears Tyrannosaurus Rex is rated “Advanced,” features 249 laser-cut wooden pieces, and offers about eight hours of immersive building fun. No glue or tools are required—everything needed is included in the box.
