The Eye-Scan Registration occurs when a commander first activates his robo. Upon doing this, he must make contact with the robo's eyes which scan the commander's eyes. This binds the commander to his robo, and no other commander can use that same robo. In game, the eye-scan is only required for the first robo, and all the other robos do not need to be activated this way, but the scan is implied. This registration has taken an air of ritual among custom robo commanders.
