I work for Sphero and develop educational content for classrooms. A lot of students program Sphero robots to navigate mazes and obstacle courses. Many of these consist of painters tape on the floor. I wanted to change that and add some complexity to the programming experience.

The new Sphero BOLT features IR and an ambient light sensor. By using these walls, you could create situations where there are light shifts and IR messages at different points in the maze. The walls would help isolate the location of the light and allow for more conditional programming opportunities for students.

There are two sets of walls. The short walls (all starting with 's_') a 100mm tall, and the taller walls are 130mm tall.

The piece together using the connectors that are included. You may need to print the tabs a little larger to create a snug fit. I also just wrapped them with some painters tape to make the tabs fit better. The 28.5 connector is for all the walls except the round turn. The 21.5 connector is needed for the round turn. The short walls use one connector on each side, while the tall walls use two.

Happy printing!
