Team 4099 was first founded in 2012 at Poolesville High School by a group of students in the Science, Math, and Computer Science Magnet program. These students wanted to have the opportunity to build robots and compete in the FIRST Robotics Competition. The students raised funds, recruited staff mentors, and formed a team of dedicated students to compete in their rookie year. The team's Rebound Rumble robot was highly capable, and the team's strategy impressed judges enough to win the team the Rookie All-Star award at the Washington D.C. Regional that year. The team then attended the FIRST Championship in St. Louis, finishing in the middle of the pack in a strong Galileo division.
ELEGOO sponsored the Neptune 2S FDM 3D printer to help the students in the team use the printer to make the parts needed for the robot.
