60666X, the division champion of the middle school and third place in the finals of last season's VEX Robotics World Championship, is back. From June 29 to July 4, they gathered together for a week-long summer training. This is a video of their first day. Before the training, each of them made a hero robot officially released by VEX. On the first day, they learned the rules of the new season, tested the hero robot by programming the robot, and optimized their hero robot.
