2025 Tutorials

Zero Robotics (ZR) is a programming competition where Astrobee satellites inside the International Space Station (ISS) are controlled by programs developed by YOU! You will create, edit, share, save, simulate, and submit programming code in order to accomplish whatever your given task is. After several rounds of competition, finalists will compete in a live championship aboard the ISS. An astronaut will use your code to conduct the championship competition in microgravity with a live broadcast!

Due to the transition to the new Astrobees, the following table shows the tutorials available for learning to program in the ZR IDE for the 2025 High School relaunch.

2025 API REFERENCE

The API Functions document describes the available functions that can be used in your code.

As Zero Robotics transitions from using the SPHERES to the Astrobee Satellite, we wanted to centralize your teaching tools into one location. If you have suggestions on how to improve these tutorials or the content within the educator guide, please email those suggestions to MIT’s ZR Partner, the Innovation Learning Center, at Katie@MassILC.com.
