The hands-on foundation for grades K–12. Learn to build and code real robots — then branch into CS and AI, drones, CAD, or competition teams, exploring at your own pace.
Get your builder started →Robotics is our foundational, year-round program — the on-ramp to everything else we do. Students learn to design, build, wire, and code real robots in a hands-on workshop, at their own pace and without the pressure of a competition season. It's where curiosity turns into capability.
Robotics is built for students in grades K–12, at any experience level. Complete beginners start with the fundamentals of building and block-based coding; returning students take on harder builds, sensors, and autonomous programming. Our youngest builders start with simple, age-appropriate kits and grow from there. No prior experience — and no team commitment — required.
Robotics is the starting point, not the finish line. From here, students branch in whatever direction excites them — and many explore more than one.
Keep building and go deeper — coding and AI, drones, CAD, and hands-on engineering, at your own pace. Robotics is the on-ramp to everything else we teach.
