Human-made machines, computers, Robots are called as humanoids. They cannot think by own but they are work by a pre-program.

Machines and computers are works by Processors, Controllers and some other components. The main thing is a processor, it is the brain for a Computer and robot, etc.
Assume a Tv Remote, It has more buttons and you can change a channel or increase or decrease volume by pressing the buttons it in.

The remote has pre-program of a specific button for volume and a specific button for channel changing. This is the work of a Microcontroller. This contains the program and if a button is pressed once it gives the output.
