How does robot work?

Basically, a robot made mimic our body's systems such as:
In the framework of a structure on human robot. Muscle to the effort. Robots have aktuator to manipulate Panca indra to communication for the environment. Robots have censor Energi or food for body metabolism. Robots have a battery or the brain power to control the entire body system. Robot has a computer to control the entire system.

Robot has a computer to control the entire system. Robot consists of various components that can be movement similar effort on our bodies. To manipulate components to be used aktuator. Aktuator can be a motor, selenoid, hydraulic and pneumatic.

To this arous aktuator required resources. To light batteries for motor, hydraulic pump for arous and wind for manipulated pneumatic. Aktuator connect to the electrical circuit. Circuits connected to the motor or selenoid. Motor selenoid and will manage the movement of the hydraulic system or pneumatic way valve to manipulate the system.

Example: A robot manipulate hands aktuator installed with the hydraulic system. To manipulate to hand over the electrical circuits will send a signal to the motor or selenoid to open the valve that will robot arm. The valve opens fluida that will encourage which has piston pressure in actuator and manipulate arms upwards.

All the above in the control by the computer that functions as the brain of the robot. Usually, each computer can be re-programmed, so the user can set the various movements of a robot with a new way to enter the new program to the computer.
