During which phase is the fuel added to the field?

The fuel is added to the field during the Teleop phase in the FRC (FIRST Robotics Competition). In this phase, human operators take control of the robots and engage in strategic play to score points. This is when teams utilize their robots' capabilities to interact with the game elements, including adding fuel to the playing field. The intentions during Teleop are focused on scoring and executing strategies based on the current state of the match. This inclusion of fuel plays a vital role in game dynamics, as it provides teams with the opportunity to score through specific actions, such as shooting fuel into designated scoring areas.

The other phases do not involve the addition of fuel to the field: during Auto, robots operate autonomously based on pre-programmed instructions; in Endgame, teams focus on final scoring activities and actions to maximize their game points; and Transition is not a recognized phase in the typical play structure of FRC matches. Therefore, the Teleop phase is specifically designed to allow for the interaction of players with the gameplay, including the addition of fuel.
