<SG2>
Horizontal expansion is limited. Once the Match begins, Robots may expand horizontally beyond the starting size limit within the following criteria:
• The Robot can never be larger than 24” wide or 24” long at any point during the Match (must fit within a 24” x 24” square horizontal footprint). Teams should be aware that Robots may incidentally expand horizontally while extending vertically (e.g., mechanisms that arc, swing, or deploy upward). Teams must be prepared to demonstrate that their Robot does not exceed the maximum size constraint of 24” x 24” at any point during a Match due to either physical or programmed limitations, including while any vertical expansion mechanisms are in use.
This rule has additional Violation notes. See Appendix C.
