Animatronic dinosaurs: how they work and why they are so amazing

When a child stands still in front of a dinosaur that moves its head and opens its mouth, they are seeing the result of a great deal of engineering hidden beneath the skin. Animatronic dinosaurs are life-size figures that combine sculpture, mechanics and electronics to appear alive.

What exactly is an animatronic?

An animatronic is a robotic figure designed to imitate the movements of a living creature. For dinosaurs, the starting point is the real skeleton as known from fossils. An internal metal structure is built, then fitted with motors, foam to give the body volume and flexible, hand-painted skin.

The result is no toy: these are figures several metres long, weighing hundreds of kilos and designed to work outdoors for years.

How do they move?

Each dinosaur has a series of programmed movements that repeat on a loop:

• Head and neck: they turn and tilt to follow visitors with their gaze.
• Jaw: it opens and closes, sometimes synchronised with sound.
• Tail: it sways slowly to create a sense of balance and life.
• Eyes and eyelids: they blink, a small detail that completely changes how realistic they seem.
• Breathing: the chest rises and falls almost imperceptibly.

The key is slowness: sudden movements give the machine away, while smooth, unhurried movements trick the eye and make the brain interpret it as a real animal at rest.

Why are they so amazing?

There are three reasons. The first is scale: seeing a Tyrannosaurus in a book is nothing like having one in front of you, taking up half an open space. The second is unpredictable movement: because you do not know when it will turn its head, your body reacts as though it were a real animal. And the third is the setting: a dinosaur among pine and holm oak trees, in natural light, is much more convincing than one inside an exhibition hall.

The animatronics at Dinolandia

At Dinolandia, the large dinosaur park in the Sierra Oeste de Madrid, the animatronic figures are set within a real Mediterranean pine forest. They are not lined up as they would be in a museum: they appear among the trees along the route, so every bend in the path holds a surprise.

The dinosaurs operate until 19:00, when they switch off and the park begins its transformation; at 19:30, the lights of El Bosque Encantado come on. If you want to see the animatronics in action, we recommend arriving with plenty of time before 19:00.

An outing that captivates the whole family

Animatronics achieve something difficult: leaving a 4-year-old child and their grandfather equally amazed. If you want to see for yourself, Dinolandia tickets also include El Bosque Encantado and Mineralandia: three parks in one, 50 minutes from Madrid.
