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 the dinosaurs to walk on its own two feet—the first bi-pedal 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.

Up to 13 meters in length and 9 metric tonnes in weight, tyrannosaurs had the largest teeth of any carnivorous dinosaur, capable of tearing flesh and crunching bone. They also had highly-developed senses of smell, on par with vultures, and incredibly acute eyesight—better than eagles. They were the apex predators of the late Cretaceous period, roaming over what is now western North America, in environments ranging from bayous to semi-arid plains. Their giant rear legs and swaying tail made them efficient walkers, capable of stalking prey over long distances before closing in for the kill with a burst of speed. They could also smell carrion at a great distance then chase other predators from the carcass, making them the bullies of the Cretaceous lunch room.
