In this year’s FIRST Robotics Competition: INFINITE RECHARGE two alliances of three teams work to protect FIRST City from approaching asteroids caused by a distant space skirmish.  Each Alliance race to collect and score Power Cells in order to energize their Shield Generator during the autonomous period (15 seconds) teams gain double the points for any power cell scored using pre-programmed instructions as well as moving from the initiation line. During the Teleop stage(2 minutes 15 seconds), teams can score by scoring Power Cells in the Power Port, Completing Rotation Control, Completing Position Control, Hanging from the Generator Switch and Getting the Generator Switch to the level position. Alliances win ranking points from scoring at least 65 points or unlocking all three stages. Each stage is unlocked by scoring a certain amount of Power Cell at each stage.
