From my knowledge Curiosity is a NASA-made car sent for a Mars expedition. His mission was to look for possible microbes, early organisms of life, or water on the Red Planet.

Curiosity is a six-wheeled vehicle with a robot as a motion controller. But, according to the NASA site, Curiosity has a body part like a human. As:

Curiosity has a hand named turret. Its function is to bring drills, brushes to clean dust, ground shovels, cameras, and microbial researchers tools. With the researcher's tools, Curiosity can examine rocks, mineral deposits, and carbon compounds.

Like humans, the outer part of Curiosity's body has the ability to protect the vital organs on the inside, like brain computers. Even in the shape of a car, Curiosity's body is far from the surface. Thus, the cruiser car does not have to worry about his body will hit the rocks on the surface of Mars.

At the rear, Curiosity has a tailor-made power system. Function, the flow of heat throughout the body to keep the brain normal temperature than the temperature of Mars is very cold.

Curiosity has an antenna that functions like the mouth and ears. With this antenna, he can capture the sound around it and communicate to Earth.

Like humans, Curiosity has a brain. But not on the head lies, but on the body. In addition to the main brain, this cruiser also has a backup brain. And the functions of both are exactly the same as the human brain: track the level of health, temperature, and other features that support the life of Curiosity.

Curiosity has a head and neck that carries seven of the 17 camera eyes. With this pole, Curiosity has a view like a basketball player whose height is about 2.1 meters.

This explorers car has a laser nose on the forehead that serves to sniff the safety of an object on Mars. When Curiosity sees the rocks that he finds interesting, this laser will scan the surrounding vapors.
