The labyrinth :

The labyrinth challenge featured a collision detector, and the objective was to guide the ball through the maze, activating the LED by touching the collision sensor. Successfully completing the challenge signaled progress in the quest for Excalibur.

We encountered some difficulties and changed our idea along the way. Initially, we wanted to create a hidden labyrinth, meaning placing a ball within the course and a piece of aluminum at the finish, then sealing the labyrinth. The objective was to blindly guide the ball using a magnet until it reached the aluminum, and, through its properties and a code, illuminate the LED. In the end, we decided to keep our labyrinth open as it aligned better with our theme. We chose to make it necessary to touch the collision sensor with the ball to illuminate the LED associated with that step.

We also had to create our labyrinth twice because the first one was too large in relation to the box we used as a rock.
