19. Answer the question.

20. Robots can sense things and respond to their senses
Robots can sense things and respond to their senses. This means a robot can
be programmed to think on its own.
In a robot, the sensors are the inputs.
For example, a robot can sense light and sound, the way your eyes and ears do.
Robotics would not be possible without electronics.
The most important electronic part of the robot is the brain. It allows the robot to interact with things around it. It is where all the thinking happens.

21. A robot has three main parts: 1. Sensors (Input)

19-20

22. 2. Control system (brain)
A control system is a device that manages or controls the behavior of other systems.
These act as the brain in any robotic system. They come in various shapes, types and sizes.

23. 3. Actuator/Output:
An actuator is the part of the robot that performs a physical action. Here are some examples of different types of effectors:

24. Edison robot
Edison is your new robot friend who will teach you about robotics in a fun way.
He is equipped with all the parts needed to introduce you to the amazing world of robotics.

25. You will use a set of commands or instructions to teach Edison
You will use a set of commands or instructions to teach Edison. You must teach Edison to understand its input and control its output. The set of commands or instructions is called a program.

26. The sensors are the inputs
The sensors are the inputs. For example, your Edison robot can sense light and sound the way your eyes and ears do. Look at the pictures of Edison.
Microcontrollers
The microcontroller is the main control unit of any automatic system or device.
These systems and devices have an input unit for collecting signals or sensing
the signals from an environment, a control unit for processing the received
signals, and an output unit for sending out signals or controlling an output
device.

27. Programming software
Robots can be programmed using either a visual programming or a text-based interface. In visual programming, you can use elements graphically to create programs. You can also drag and drop program elements, click, use menus, forms, dialogue boxes and so on. This type of programming helps new users to understand programming easily. In text-based programming, you must understand the language syntax and rules. You can cut, copy, and paste your code which gives you more flexibility compared to dragging and dropping one block at a time.

35. 1. Sensors (Input). 2. Control system (brain). 3. Actuator/Output.
A robot has three parts:
1. Sensors (Input). 2. Control system (brain). 3. Actuator/Output.

36. The main parts of a robot
Sensors (Input):
tell the robot about its surroundings.
2. Control system (brain):
A control system is a device that manages or controls the behavior of other systems.
These act as the brain in any robotic system. They come in various shapes, types and sizes.
3. Actuator/Output:
An actuator is the part of the robot that performs a physical action.
