How to Make an Animatronic Tyrannosaurus Rex

Animatronic dinosaurs are known for their ability to evoke a frightening feeling. As you walk close to these dinosaurs, they might suddenly open their bloodied mouths, sway their arms, and emit chilling roaring sounds. so, next, let me show you how to make an animatronic tyrannosaurus rex.

Here’s how an Animatronic Tyrannosaurus Rex is produced:

Internal skeleton design

Step 1: Weld the skeleton of the dinosaur using steel materials.

Install motor and wiring

Step 2: Install motors and wiring.

Preparing to carve the shape

Step 3: Wrap a layer of sponge for sculpting.

Step 4: Sculpt the general shape of the dinosaur.

Step 5: Use an electric soldering iron to create the texture of the dinosaur’s skin.

Skin making

Step 6: Apply a layer of mesh on the skin and then brush silicone.

Finished product testing

Step 7: Spray paint for color and conduct final product testing.

An animatronic tyrannosaurus rex mainly consists of a steel structure, transmission equipment, high-density sponge, silicone skin, a control box, and other components. The steel frame plays the role of supporting the dinosaur’s skeleton, while the sponge wrapped outside is driven by mechanical parts to perform all movements. Therefore, the steel frame serves as the skeleton of the dinosaur.

In fact, the material for the muscles is quite simple; it’s commonly seen high-density sponge. However, due to the skilled craftsmanship and research, this simple material transforms into muscles that mimic those of a real dinosaur. This transformation is achieved because the inner part of the animatronic tyrannosaurus rex is installed with a variety of motors, reducers, and other transmission equipment.

After the mechanical and electrical engineers design and program the steel frame, it is able to move driven by motors under the set programming of the control box. This movement then promotes motions of the “muscles” and “skin” of the animatronic Tyrannosaurus rex, allowing it to make different kinds of realistic movements.
