What is the maximum size limitation for a robot, according to the FTC Decode 2025-2026 rules?

The maximum size limitation for a robot in the context of the FTC Decode 2025-2026 rules is that it must fit within an 18-inch cube when starting the match. This means that all parts of the robot must be contained within an 18-inch x 18-inch x 18-inch volume at the start of the game. This size restriction is important for ensuring that all robots can fit within the designated starting areas on the field and contributes to maintaining a level playing field among teams.

The rules include this limitation to facilitate compact and efficient designs, encouraging teams to innovate within the constraints. In addition, after the match begins, robots are allowed to expand beyond this size limitation during gameplay, promoting diverse strategies and adaptations while still maintaining initial size restrictions.

The other options propose size limits that are either larger or not relevant to the starting constraints of the robots in competition, thus making them incorrect in this context.
