To guide users in engaging with the game and project, we added signs indicating the steps and actions they should take. For instance, to start the game, the user first activates the servo, which will point to a specific obstacle that the player must complete. We designed the servo as a spinner with labeled choices representing each obstacle, along with a “Start Here” sign to indicate that players should activate the spinner first rather than selecting options at random. Each obstacle also had its own sign to clarify the required actions. For example, the vibration sensor was turned into a metro station, with a sign reading “Make the tracks shake,” indicating that players must cause the board to vibrate. Another example is the pressure sensor, dressed as a rat tail, where a sign instructed players to “pinch” the sensor.

Our project was constructed primarily from sturdy cardboard, which provided good structural integrity. Given the large number of motors, breadboards, and components we used, we created a box-like structure to conceal the wires and breadboards inside, while keeping the sensors visible on the top, creating a cleaner and more organized look. One innovative solution we implemented was zip-tying all the breadboards, Arduinos, and motors to the base of the box, as these components would shift while being transported, and securing them in place was essential to maintain their functionality.

Using cardboard was effective overall, though we encountered some issues. For example, we initially cut large holes in the cardboard to allow rat cutouts on stepper motors to “pop out” once players completed an obstacle. However, when we had to redo the board layout, we needed to patch these large holes. We managed to resolve this by reinforcing the cardboard with cardstock, effectively restoring the board's structure and appearance.
