Questions and Answers

What are the two distinct types of information that mBot2 robot can display?

Static and dynamic information

Give an example of static information that you can display on the mBot2 screen.

My name - Hello - etc

From the category 'Display', examine all the available blocks.

The 'Display' category provides blocks for displaying information on the screen, like text, numbers, and images.

From the category 'Sensing', examine the blocks to read the ambient light intensity, loudness as well as the timer.

<p>The 'Sensing' category has blocks for reading sensor data, including ambient light intensity, volume, and the timer.</p> Signup and view all the answers

Examine the mission to display a variable information read from the ambient light intensity.

<p>The mission involves using a block from the 'Sensing' category to read the ambient light intensity and displaying it on the screen using a block from the 'Display' category.</p> Signup and view all the answers

From the category 'Variables', create a new variable "count" then examine the different blocks available.

<p>The 'Variables' category allows you to define variables, which are like containers that can store data. The blocks available in this category include creating and managing variables.</p> Signup and view all the answers

Create the script and describe the behaviour of the mBot2 robot.

<p>The script uses a 'when clicked' block to start the robot's behavior. It then uses a 'set' block to initialize the 'count' variable to 0, and then uses a 'repeat until' block to continue the loop until the 'count' variable is greater than 50. Inside the loop, it uses a 'print' block to display the current value of the 'count' variable on the screen and then uses a 'change' block to increment the 'count' variable by 1.</p> Signup and view all the answers

What will the mission display on the screen?

<p>The mission will display the numbers from 0 to 50.</p> Signup and view all the answers

Study Notes

Displaying Information

  • Static information is unchanging data.
  • Dynamic information is ever-changing data.
  • mBot2 robots can display both static and dynamic data.

Examples of Static Information

  • My name - Hello etc.

Examples of Dynamic Information

  • Distance - Light - Sound etc.

Display Blocks

  • Examine all available blocks in the Display category.
  • Examine the blocks in the Sensing category to read ambient light intensity, loudness and timer.

Variable Information

  • Examine the mission to display variable information from ambient light intensity.

Creating New Variables

  • Create a new variable called "count" in the Variables category.
  • Examine the different available blocks.

Challenge

  • Create a script for an mBot2 robot to display numbers from 0 to 50 on the screen.
  • When a clickable event occurs, set count to 0.
  • Repeat the process until count is greater than 50.
  • Print count and move to a new line.
  • Increase count by 1.
