A fighter robot system that supplies power to two fighter robots, which have a match against each other, through respective power lines and prevents the power lines from becoming entangled even when the robots are moving. The fighter robot system includes two fighter robots, a power supply providing power to the fighter robots, and a rotary member located above or below the fighter robots, the rotary member having a predetermined length and rotatable around a central axis formed at a predetermined portion. The power supply provides the power to the fighter robots through power lines. Each power line starts from the power supply, extends from the central axis to either end of the rotary member in the lengthwise direction, and is connected at that end to each fighter robot. The rotary member rotates around the central axis following the movement of the fighter robots.
