Ri3D (Robot in 3 Days) is a traditional activity in the FTC/FRC community, where teams complete the design and build of a functional robot within 72 hours after the new season rules are released. This is not only an extreme challenge of team capabilities, but more importantly, it provides early design ideas and technical references for the global community.

By open-sourcing our design files and build process, we hope to:

• Help other teams quickly understand the new season mechanisms
• Provide viable design solutions as a reference starting point
• Promote knowledge sharing and collective progress in the FTC community
