The BotLoad automated charging station only requires a 5 Volt, 300 mA USB power supply. The opening and closing of the contact paddles are triggered by a light dot displayed as part of the video program. With the boat stationed at the charging station for about 1/10th of its operating time the battery will remain charged at all times. Other accessories (I.e. drawbridges, cranes, etc.) can also be controlled from optical markers on the video screen guaranteeing synchronization between them and the boats’ action.
