The competition for Applied Robotics (ROB421/521) Spring 2018 was a game of catch!
Essentially, you played catch with both yours, and your opponent's robot, with a scoring system that allotted points to various actions that could be taken by either team. You can see two matches that we played below, in addition you can find the final rules here.
Essentially, for Adversarial, the human's goal was to throw the ball in a way that the robot couldn't catch it, with the robot attempting to return the ball in a way the robot couldn't catch it. During cooperative mode, the goal was to get as many complete human->robot->human interactions as possible.
