Robot

The Laputian Robots are ancient automatons that appear in the film, Castle in the Sky.

Appearance
The Laputian robots are much taller than human beings though appear humanoid, with broad, triangular torsos and long, thin arms that reach almost to the ground. The arms can also extend flaps to allow the robots to fly. The robots have dome-shaped heads with uneven eyes; the left eye is about twice the size of the right eye. They can shoot destructive lasers of varying force from their eyes. They appear to be made out of an extremely strong, dark metal, and they have the crest of the royal family of Laputa on their chests.

History
The first robot seen in the film fell from Laputa and was recovered by the military. The military brought it to their base at Tedus and attempted to discover how it worked, without any success. Although Muska tells Sheeta that the robot is "dead", when she activates the Aetherium crystal on her necklace with a spell she learned from her grandmother, the robot comes back to life. The robot nearly destroys the base trying to reach Sheeta, whom it is programmed to protect, as she is Laputian royalty. When it gets to Sheeta on the roof of the fortress, the robot does protect her, but it is ultimately destroyed by the airship Goliath.

When Sheeta and Pazu reach Laputa, they discover many more robots, but all save one are inert and deactivated. The single surviving robot spends its days tending the Laputian plants and animals, including several fox squirrels, and leaving flowers on a gravestone. The robot is kind and gentle to the children as well, and Pazu realizes that although it is the last of its kind, it isn't lonely because it has the animals as friends.

However, when Muska seizes control of Laputa, he activates many of the inert robots, which he uses as weapons to attack the military and destroy the Goliath. After Sheeta and Pazu recite the spell of destruction that tears most of Laputa apart, nearly all the robots fall into the sea and are destroyed. As the children fly away from what remains of Laputa, they see the gardener robot has survived and is still taking care of the island's flora and fauna.

Tasks
The robots are controlled from Laputa by a computer or activated by a flying stone. Your responsibility is Laputa's maintenance and protection  and the protection of the royal family. The apparently defective combat robot rushes to Sheeta after she has activated her flying stone.

In addition to fighting, the robots maintain the gardens on the island and protect the animals that live there. They also greet the guests and guide them through the city. They probably don't repair robots or broken spots, because otherwise no combat robot would fall from the sky.

Abilities
They have extensible legs and arms. Wings are attached to the latter so that they can fly. They can also climb effortlessly with their limbs. In their face they have two eyes of different sizes that are equipped with sensors. The eyes blink red when they hear noises. From the smaller eye they fire a laser that can melt steel.

Muska's scientists couldn't figure out what material they were built from. They can withstand heavy cannon fire. A single robot could fortress Tedis destroy the surrounding settlement if the Goliath had not been near.

Weaknesses
Due to their agility and brutal destructive power, the combat robots are serious dangers that can destroy anything out of blind obedience. A robot was destroyed by a Goliath cannon. Apparently Goliath's projectile was armor piercing and the pushing force destroyed the internal mechanics.

When Laputa self-destructs, the robots are deactivated and fall apart. Only robots for maintenance remained.

Origin
The army had a seemingly broken robot that had fallen from the sky. This provided the definitive proof that Laputa really exists and was not just a fictional place from Gulliver's Travels. So the government made efforts with Muska to find the place in question.

Trivia
In Minecraft, the Iron Golem's holding out flowers to villagers is a reference to the ancient robots in Hayao Miyazaki's animated film Laputa: Castle in the Sky.   When the villager children notice the poppy in its hand, they slowly approach, and take the flower eventually. Iron golems do not actually pick up poppies; they spawn them in their hands.
