Removable Holder Each Trilobot comes equipped with a removable battery holder that allows easy access to the batteries. 8 D-cells are required to create the 9-12 volts needed for proper operation. Labels indicate battery orientation and circuitry on the main controller board prevent damage from reverse polarity. Current Consumption The Trilobot consumes approximately 400ma of current excluding drive motors and servo motors. Drive motors normally raise this value to 1 amp. RC servo motors also increase current consumption but their usage is normally intermittent.
