Are teams allowed to change the robot's structure during the rebuild?

The option indicating that teams are allowed to change the robot's structure during the rebuild as long as they adhere to the rules is correct because it reflects the flexibility given to teams to improve their designs and functionality, which is a fundamental aspect of the robotics competition. During the rebuild period, teams are encouraged to make modifications based on performance evaluations and challenges faced during matches.

However, while teams have the freedom to alter their robots, they must ensure that these changes comply with the established rules and guidelines set forth by the competition. This includes adhering to size limitations, weight restrictions, and safety protocols. The ability to modify the robot allows teams to innovate and problem-solve, which is a key component of the learning experience in robotics competitions.

The other choices imply various restrictions that limit teams' ability to improve their robots, which would undermine the educational and competitive spirit of the event.
