According to the FTC's rule R503 for the 2025-2026 season, robots are limited to use up to 10 servos rather than 12. This will create challenges for teams who need more servos to control many actions.

We created a video to present our "Multiple Functions, One Actuator" designs that were used during our robot summer camp training in late June 2025. We thought it would be better to publish these clever designs to all teams so that all students can learn how to build unique and highly efficient robots. Enjoy!
