A robot is a machine that performs a task or a variety of tasks automatically following a program

A program is a list of orders

# data[].attributes.body
Most of robots are "robotic arms", wich work in production lines

The actuator has a "manipulator", and system of articulations

# data[].attributes.body
The robot moves in a line along X (Distance), Y(altitude), and Z(Rotation)

# data[].attributes.body
Most robots "work" on productions lines, especially where the activity os repetitive, dangerous or tiring

# data[].attributes.body
It's hard to say exactly when robotics began.

Some historians date the beginning or robotics to the middle ages, when machines were first used without direct human control

# data[].attributes.body
Artificial intelligence in the capacity of the microproscessor to "learn from experience"

# data[].attributes.body
The power system generates the power necessary to move the arm and the manipulator of a robot.

There are three types of power system: Electric, pneumatic, and hydraulic

# data[].attributes.body
Sensors detect position, temperature, acceleration, etc.

Sensors pass the data to the processor as an electric signal.

There are different types of sensors for each physical parameter that can be measured.

# data[].attributes.body
The controller is the microprocessor that receives the signals (data) from the sensors, "decides" what the actuators must do, and then "tells" the actuator and the articulations of the arm when to move or stop.

These "decisions" follow the program which was written by the programmer.

Depending on how complex the robot is, the controller can control the speed of the movement, the force of the movement, etc.

The of freedomare the number of axis along which the robotic arm can move, or around which the arm of the robot can rotate.

The minimum is one, and the maximum 6
