The power circuit has a main switch that avoids battery discharging during transportation or storing. Battery voltage is feeded directly, a DC/DC voltage converter provides low voltage to the logic electronics subsystem. The battery voltage is feeded camera module allowing high voltage motors. Both battery terminals are directly exposed to the charger station allowing the carge process during rest periods.

To provide low voltage (5v) the OKI-78SR-5/1.5-W36E-C DC/DC switching regulator is used. It can provide 1.5A @ 5v and can stand inputs as high as 36v input. With this regulator we feed all the electronics contained in the carrier unit the camera module electronics use the same component to provide low voltage to it's own electronics.
