An android is a robot designed to look or behave like a human being. The term "android" refers to certain robots that bear some resemblance to human beings, both physically and behaviorally. Historically, androids were completely within the domain of science fiction and frequently seen in film and television). However, technological innovation is advancing in leaps and bounds, and these beings made of nuts and bolts, cables, and microchips are getting closer all the time.

Some key points about android robots include:

• Appearance: Androids are designed to resemble humans to some degree, with the resemblance ranging from relatively mild to scrupulously life-like in appearance.

• Function: An android differs from robots and cyborgs in both form and function. A robot is any guided machine that can perform tasks, while a cyborg is a human being with robotic body parts or mental components. Androids are not actually human but are physically designed to resemble humans to some degree while having the controllable functions of a robot.

• History: The concept of a human-like artificial intelligence has sparked the imaginations of inventors and fiction writers for several centuries. In the 15th century, Leonardo Da Vinci designed and possibly built a robot knight that could move its arms and legs. Some android enthusiasts reference an earlier mention of androids, dating back to the 13th century.

• Examples: Walt Disney famously used animatronic androids to provide the rides at Disney parks with lifelike characters. In the 21st century, Japanese and South Korean robotics companies have emerged at the forefront of android development.

Its worth noting that while the term "android" is used in reference to human-looking robots in general (not necessarily male-looking humanoid robots), a robot with a female appearance can also be referred to as a gynoid).
