WiggleBlock

Theory

• The WiggleBlock is an R/C Servo. R/C stands for Remote Control; these servos are most often used in remote control toys.

  Servos know what position they are pointed in. You can tell them to point in any direction they are capable of.
  These servos can move 180 degrees (half a turn).

  Servos do not spin in circles. Also they do not move at all if they are already at the angle you tell them to move to. To see them move you must move back and forth between different angles.

 

Assembly

1. Required Materials

   
   
   
   • R/C Servo
   • Brick (2x2) with hole
   • Brick (2x3)
   • 2 Bricks (2x2) Optional
2. 
   Put a silver stripe on the side of the connector with the brown wire
   this is the G = Ground side
3. Connect the servo to the BrainBlock
4. 
   Make sure you are connected.
   See the mBlock instructions for more details
5. 
   Add this block
   Make sure you change it to pin 2
   Click on the block to run it
6. 
   Your servo is now exactly positioned at 90 degrees
   Keep it plugged in for the next steps
7. 
   Your package has 3 screws
   Choose the small screw
   (the two big ones won't fit properly)
8. 
   Check with Mr. Dash before continuing
9. 
   The top block needs to be superglued and screwed on
   Place a very tiny amount of superglue in the bottom hole of the 2x2 brick
10. 
    Place the top block onto the servo
    Screw it into place
    Make sure it is on straight
11. 
    Remove all the stickers from the Servo
    (One on each side and a there may be a tiny one on the bottom)
    
12. 
    Sand and acetone the top bumps of the 2x3 brick
13. 
    Sand and acetone the bottom of the servo
14. 
    Check with Mr. Dash before continuing
15. Place 6 drops of superglue on the bumps of the 2x3 brick
16. 
    Carefully place the 2x3 on the bottom of the servo
    
17. 
    Hold the brick in place for at least 1 minute

18. Optional

    
    
    Sand, Acetone, and glue a 2x2 brick on each side
    Make sure you glue the top of one brick
    and the bottom of the other

• To see the WiggleBlock Move make sure you have two blocks like below with angles different from each other.
  You can type any angle between 0 - 180.

• Mini Challenges

  • Put a "head" on your WiggleBlock, then create 2 sprites: one to turn the head left, the other to turn right
  • Make a sprite that makes the head shake back and forth (say no)
  • Make a sprite that makes the head shake back and forth slowly
  • Make a mood gauge: put an arrow on the WiggleBlock, then make a sheet of paper with 5 moods like (Angry, Happy, Sad, Silly, Surprised) make a sprite to point to each mood
