Instructions

1. Plug the robot's USB cable into the computer FIRST
2. Run the Birdbrain Robot Server.
3. Start SCRATCH for Finch. DO NOT CLOSE the Control Window.

1. Create this program

Notice that:

• YELLOW blocks come from CONTROL
• PURPLE blocks come from LOOKS
• BLUE blocks come from MOTION
• Finch blocks come from MORE BLOCKS

 

1. Using the first Scratch program, answer these questions:
   1. How can you tell that the robot is getting power?
   2. How do you start and end the program?
   3. What should happen?
   4. Does it work?
      • Why or why not?
        
        

2. Create the code below and add it to your program

2. Answer these questions when you run the program:
   1. What color does the Finch's beak change to?
   2. How far does the Finch travel? (measure it)
   3. Does the Finch move in a straight line?
      • Why or why not?
        
        
        
        
   
   
   

3. Change the block to say 3 seconds instead of 1 second. Run the program.
   
   

3. How far does the robot go when you change the wait time to 3 seconds?
   • Is it exactly 3 times farther than it traveled at 1 second?
   • Why?
     

4. Change the numbers in the MOVE block to say -60 instead of 60.
   Run the program.
   
   

4. What happens if you change the MOVE block to say MOVE FINCH LEFT:-60 RIGHT: -60 using negative numbers?
   

5. Remove the block altogether. Run the program.
   
   

5. How far does the robot go if there is no wait block?
   • Why?
     

6. Does anything change if you remove the Stop all block?
7. RGB stands for Red-Green-Blue. You can create different colors by changing the numbers.
   100 means the color is on all the way
   0 means that color is turned off
   

   Modify your program so that the robot goes: forward for 2 seconds showing a BLUE light and then backwards for 2 seconds with a RED light. Demonstrate your program to the teacher.

6. Does the stop all block make a difference?
7. What numeric color code would you use to show purple?
