What types of modifications are allowed during the competition season?

The correct answer indicates that teams are encouraged to make adjustments to improve their robot's performance throughout the competition season, provided these modifications adhere to the established rules. This approach fosters innovation and learning, as teams can iterate on their designs and implement improvements based on matches and experience gained during competitions.

This flexibility in making modifications allows teams to respond to challenges they encounter, optimize their strategies, and enhance reliability and efficiency. Compliance with rules ensures that all changes made uphold the spirit of fair competition, emphasizing safety and fairness among all participating teams.

The other choices suggest a more restrictive or incorrect interpretation of the rules. For instance, implying that no modifications are allowed contradicts the competitive nature of robotics, where ongoing development is key to success. Likewise, stating modifications should remain untested demonstrates a misunderstanding of the iterative process involved in robot design, which typically involves testing and refining designs to ensure optimal performance.
