In some large scenic spots and parks, we can often see the figures of animatronic dinosaur models, or they can show their teeth and claws, or they can be charmingly naive, and they can also make vivid movements
The common material is sponge silica gel, which is characterized by softness and elasticity. And the touch is very real, just like touching real creatures. The dinosaur model with action function can be made by installing motor and transmission structure inside.
When making, first use channel steel, round tube, square tube and other steel, according to the design drawings, cut the dinosaur shaped steel skeleton. Then welding is carried out according to the action of the simulation dinosaur model. The moving part is welded into the moving joint, and the non moving part is directly welded into the fixed structure.
Next, the dinosaur was equipped with a motor and a transmission structure. The motor could use a DC brush motor or a stepping motor, while a pneumatic simulation dinosaur could only use a cylinder. No matter with motor or cylinder, coolie model can be made, but the cost of cylinder is higher.
