Which of the following is NOT a responsibility of volunteers at an FRC Crescendo event?

In the context of an FRC Crescendo event, volunteers have various responsibilities that are crucial for the smooth operation and fair competition of the event. Judging matches involves assessing the performance of teams based on predefined criteria, which is a key role for those who are trained to understand the nuances of the game and the teams' strategies. Ensuring rules are followed is essential for maintaining the integrity of the competition, as volunteers monitor adherence to established guidelines throughout the event. Assisting in match operations is another critical task, where volunteers help facilitate the flow of matches, ensuring everything runs efficiently.

However, providing technical design feedback is typically not within the responsibilities of volunteers at the event. This task is usually reserved for mentors, coaches, or specific judges who are tasked with giving detailed evaluations and constructive criticism on the robots' designs and performance. While volunteers may offer general assistance and support, detailed technical feedback requires expert knowledge and is not a primary role assigned to them at the event. Thus, this option accurately reflects a responsibility that falls outside the usual scope of volunteer duties at an FRC Crescendo event.
