How do robots work?
Automated mechanisms and robots
Uses and classification of robots
The micro:bit controller board
Is a device or machine that performs a specific task and whose operation cannot be changed
A robot is a progammable automated machine that captures information about its surroundings, processes this information and act on it
An automatic mechanism constantly repeats the action that it has been designed for and this cannot be changed.
A robot is reprogrammeable and reacts in different ways based on the information that it receive from its enviroment
By their morphology
A robot usually performs tasks to replace or extend human labour.
By their field of use
Service robots
Medical robots
Industrial robots
Defence, security and surveil-lance robotics
Land, sea and air robotics
Are uses for different types of tasks
Are domestic robots educationnal and toy robots, assistive and companion robots, etc
Are used in surgery, for the treatment of diseases and injuries, in prosthetics, etc
The robost curenty being developed in this field include autonomous vehicles, unmanned submarines and drones
Detect and deactivate explosives, tracker robots and surveillance robots, among others
Welding, cutting, painting, operations in nuclear pants, moving, assembly, etc
Nanorobots can be very important in this field
Mobile
Polyarticulated
Zoomorphic
Android
Controller processes
Actuators act
Sensors perceive
How robots act
How robots control
How robots perceive
Sensors are the elements rosponsible for perceiving the signals from the enviroment.
These devices detect physical or chemical variables and transforms them into electrical variables
Temperature sensor
Ulltrasonic distance sensor
Light sensor
PIR or motion sensor
Infrared sensor
Contact sensor
Actuators are elements that execute orders hat they receive from the controller
These devices convert electrical energyto anither type of energy to operate motors, switch on lights, emitsounds, etc.
Servomotor
Buzzer
Direct current motor
LED
The controller processes signals from the sensors and canculates the orders that it must give to the different parts of the robot
Controller boards that we will use in this unit
Micro:bit board
Arduino board
