    Robots consist of several key components, including arms or manipulators sensors, actuators and
                     controllers. The controller acts as the main processing unit, enabling the communication between
                     these components. Its main role is to interpret the information received from one part of the robot
                     to another. The task the robot is designed to perform is the input, while the task it actually carries
                     out is the output. Sensors detect and send signals as information, helping the robot understand
                     its environment.

                     BUILDING BLOCKS OF ROBOTS

                     A robot is made up of three main parts or blocks: mechanical, electronic and computational.
                     These blocks work together to give a robot its abilities and functions.

                                                                     Robot

                                                            Building Blocks of Robots

                     Mechanical Block

                     The  mechanical block  includes  the physical  parts of the robot  such as the body,  joints  and
                     actuators. It allows the robot to move and interact with its surroundings. For example, motors
                     help a robot walk, turn or lift objects.

                     Different robots have different mechanical designs — humanoid robots have multiple joints to
                     move like  humans, drones have light frames to  fly  and underwater robots  have waterproof
                     sealed, pressure-resistant bodies with propellers for movement.
                     Electronic Block

                     The electronic block helps the robot sense, process and respond to its environment. It includes
                     sensors, microcontrollers and circuits. Sensors act as the robot’s eyes and ears, allowing it to
                     detect light, sound, distance or movement. The electronic block collects this data and sends it to
                     the controller for processing.

                     For instance, drones use cameras and GPS, underwater robots use sonar and mobile robots use
                     sensors to detect obstacles.

                     Computational Block

                     The computational block is like the robot’s brain. It includes software and algorithms that process
                     information, make decisions and control the robot’s actions.

                                                                                           Robot as a System
                                                                                                                        19
