Art Canvas Plus Playground with the VR Robot on the playground having already drawn lines of multiple colors in the pattern of a magic flower.
Launch VEXcode VR now

Design an algorithm to use [Drive for] and [Turn for] blocks and the VR Pen on the VR Robot to create a six-fold symmetry magic flower on the Art Canvas+ Playground.

  • Select the Art Canvas+ Playground.
  • Design an algorithm to create a six-fold symmetry magic flower.
    • Use the VR Pen to fill the Playground area with a background color.
    • Use a variable to store the number that represents a specific color.
    • Select a Pen color according to the variable value. Utilize the Pen on the VR Robot and use a loop to repeat the [Drive for] and [Turn for] commands for a set number of times to code the VR Robot to draw a diamond shape petal on the Canvas.
    • Change the variable value to represent a different color. Turn the VR Robot for certain degrees to get ready to draw the next petal.
    • Use a loop to code the VR Robot to repeat the actions for a set number of times to draw six petals in various colors and directions to create a six-fold symmetry magic flower.

Helpful Hints

  • The angle the robot needs to turn to draw a six-fold symmetry flower is 60 degrees:
    • The angle to turn = 360 / symmetry = 360 / 6 = 60

  • Use My Block from the My Blocks category to create a custom block to code the VR Robot to select a specific Pen color according to the variable value and use it in the project. The My Block makes the project shorter and more easily readable.

    VEXcode My blocks Definition block that reads 'define chooseColor'.

    • Matching Python command:

      def chooseColor():
  • For help with using My Blocks in the project, please select the “TUTORIALS” button in VEXcode VR and choose the My Blocks Tutorial.
