Having a Servo around can be very convenient, as they have fewer needs and are therefor less demanding of your attention than their organic counterparts. However like any sim they require energy to continue performing, which can be unappealing if you need them going for long periods of time. With the Servo Auto-Charger mod you can now purchase a broadcaster from the Electronics section of Buy mode which will wirelessly charge all Servos within its range, allowing them to function for much longer without needing a recharge.
