Robot and digital electronics
What is a robot?
is an electromechanical system that can carry out tasks automatically based on the information it receives from its surroundings.
Components of a robot:
Control System:
is the robot's "brain," programmed to perform tasks by analyzing information from its surroundings.
Actuators:
These devices generate the robot's output. They convert electrical energy into another type of energy, like motion, light or sound.
Sensors
: collect information and send it to the control system, allowing the robot to react accordingly.
Types of machines and systems:
Mechanical systems:
Instead of doing a task manually, the user controls a machine that does it for them.
Robotic systems:
Perform tasks by analyzing surroundings and making decisions based on sensor input. These are
closed-loop systems
, as sensor input guides the system's behavior and output.
Automated systems
: operate without human intervention, with the operator only supervising. These are
open-loop systems
as they lack feedback from sensors to verify if the system's goal is achieved.

Function of robotic arms:
Robots designed to manipulate tools or parts without direct contact are called robot manipulators or robotic arms.
Cartesian:
With three linear axes of control, these robots can move up/down, back/forth and in/out.
Cylindrical:
With two linear axes and one rotary axis, these robots can move up/down and back/forth and rotate.
Spherical:
These have two rotary axes and one linear axis.
What are digital and analog systems?
Digital:
systems work with discrete variables that can only take on certain values from a finite set.
Analogue systems:
Can work with continuous variables with an infinite number of values. Physical variables like temperature and light are analogue and can take on any value.
Basics of Boolean algebra and logical functions:
George Boole developed a mathematical system for two sets, represented as true/false or one/zero. Claude Shannon later applied this to electronic circuits, paving the way for computers. In digital circuits, 0 means no voltage, and 1 means a voltage of about 5 V
