Two "robots" start back to back. A "programmer" sets the robots in motion by touching the "on/off button" on their heads. The "robots" move to the beat of the music (speed). If a robot is touched on the left or right shoulder, it makes a 90-degree turn to the corresponding side and continues to move. After starting the robots, the programmer may not issue any commands for five seconds. When a "robot" reaches a wall, it makes a 180-degree turn. The aim of the "programmer" is to bring the "robots" back together again.
