Activity: Wirelessly Controlled Robot

Let’s Code

1. Open PictoBlox and create a New File.
2. Select the coding environment as Block Coding.
3. Power up the Quarky and connect it to PictoBlox as shown in the previous topic.
4. We want to ensure that Quarky moves forward only if the up arrow key is pressed. To check if it is pressed, we’re going to use an if block. Go to the Control palette and drag and drop an if-else block.
   
5. Now, go to the Sensing palette and add a key () pressed? block inside the diamond-shaped space of the if block. This block will check if the selected key is pressed. The up arrow key is the default option.
   If the up arrow key is pressed, we want Quarky to move forward. Therefore we will now add a go () at () % speed for the () second block.
6. Go to the Robot palette and add a go () at () % speed for () second block inside the if block.Now, we need to do the same for the remaining three directions.
   
7. Duplicate these blocks by right-clicking the if-else block. Then, in the key () pressed ? block, change the key to down and in the go () at () % speed for () second block, change the direction to backward.
   
8. Repeat step 6 two more times for the remaining two directions.
   
9. Now put the stop robot block in the last else branch.
   
10. Complete the script by adding a forever & when flag clicked blocks at the top.
    
11. Save the file with the name Wirelessly Controlled Robot.

Now, run the script by clicking the green flag. Have fun playing with Quarky!
