From the robot description:
Depending upon the game you select (or modify using the software) each accessory serves a unique purpose: the base station can act as a depot, timer, or target; the energy port ejects a ball (which is corralled by the robot's built-in scoop) and recharges the robot; and the special effects hub provides robots with advanced maneuvers and abilities. The robot has infrared sensors and radio frequency identification chips that allow the robot to react to the game's accessories and other competing robots, helping it to avoid obstacles, navigate autonomously, and participate in any of the six included games. The games involve the robot picking up different colors by driving over encoded pads and delivering them to the hub before time expires, collecting a ball while avoiding "bullets," dropping electronic "land mines" to obstruct competing robots, and more.
