Modifications

The Romi chassis has multiple power options built into the battery compartment, as discussed in [[Pololu-Romi-Chassis-Alimenter|Options d'alimentation]] of the Romi Chassis User’s Guide. If you are using the 4 battery configuration with the Romi chassis, you can power the servos from the battery voltage. Please note that using all six batteries in series can result in voltages upwards of 9 V with fully-charged NiMH batteries, so you should not power your servos directly from the batteries in this configuration. In this case you can use a [https://www.pololu.com/category/131/step-down-voltage-regulators step-down voltage regulator from Pololu}} such as our "6V, 2.5A Step-Down Voltage Regulator D24V22F6" {{polpl|2859}} to safely power the servos.

{{ambox|text=If you use the "Power Distribution Board for Romi Chassis" {{polpl|3541}}, it defaults to getting power from all six batteries, but it can be reconfigured to be powered from four cells; see the board’s product page for more information.}}
