Patent ID: 8758077

Claim:
A fighter robot system comprising: two humanoid fighter robots configured to have a fight against each other, wherein the fighter robots are powered through wires and able to walk freely forward, backward and side to side to fight each other and meet each other when fighting; 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 according to a movement of the fighter robots, wherein the power supply provides the power to the fighter robots through power lines, each of the power lines starts from the power supply, extends from the central axis to either end of the rotary member in a lengthwise direction, and is connected at that end to a corresponding one of the fighter robots, and the rotary member rotates around the central axis following movement of the fighter robots, thereby preventing the power lines from becoming entangled, wherein each of the power lines is configured as a spiral such that the length of each power line is variable to freely correspond to movement of the fighter robots, wherein the rotary member includes a first entanglement-preventing means provided on the central axis, wherein the first entanglement-preventing means prevents the power lines extending from the power supply from becoming entangled on the central axis, wherein the rotary member includes a second entanglement-preventing means on opposite ends thereof, wherein the second entanglement-preventing means prevents the power lines connected to the two fighting robots from becoming entangled with each other or themselves, wherein the rotary member includes a third entanglement-preventing means provided on upper portions of the two fighting robots, wherein the third entanglement-preventing means prevents the power lines connected to the two fighting robots from becoming entangled with each other or themselves, and wherein each entanglement-preventing means includes an external housing and an inner rotary body, the inner rotary body being able to rotate inside the external housing, and wherein the power lines extending into the external housing from the power supply are electrically connected to upper and lower contact portions provided in upper and lower inside portions of the external housing in contact with the inner rotary body.
