Grid System


  • Find a square-shaped piece of cardboard.
  • Create a square grid (8"x8" / 20x20cm or 10"x10" / 25x25cm are good starting places).

Sketch your Maze


  • Using a dark marker, sketch out where the walls of your maze will go. 
  • Make it as simple or complex as you want! You can look at other examples of mazes online for ideas.

Maze Walls


  • Cut strips of cardboard to fill in the walls of the maze.
  • Use hot glue to start adding walls one at a time.
Be careful using hot glue as the dispenser and fresh glue can cause burns. Older Makers should help very young Makers with these steps.

A beautiful cardboard maze, ready to be robotically navigated.



  • Build a square frame to hold the maze using some strips of cardboard.
  • Connect a servo to one edge of the frame, connect the maze to the opposite edge of the frame with a short bolt. This servo will control the x-axis.



  • Create a base to hold the maze and frame. 
  • Install a second servo motor in one side. This servo will control the y-axis.

Use hot glue to connect the servo arms to the edge of the maze frame. Once the glue has cooled and hardened, press the arm onto the servo horn. 

Once the maze has been suspended in its frame, you can connect the servo motors up to Circuit Playground Express and test out its responsiveness.

Enjoy playing with your robotic labyrinth!
