What rules govern robot height restrictions during a match?

Robots must adhere to specified height limits during a match to ensure safety and fairness in competition. These height restrictions are established to minimize the risk of interference with other robots and to maintain a level playing field. Adhering to the height limits helps to create a consistent environment in which all teams can compete, preventing any one robot from gaining an unfair advantage due to size.

The other options do not reflect the established regulations in competitions. For example, if there were no height restrictions, it could lead to significant disparities in robot designs and capabilities, creating safety concerns. Determining height by weight is not a standard practice, as height and weight are separate dimensions in robot design. Allowing robots to adjust their height at any time could lead to complications and unpredictability in the match, undermining the structure of the competition and the established rules.
