The robot is equipped with two Li Po batteries (7.4V, 2200 mAh) . One for supplying the DC motors and the other for supplying the rest of electronic components. After opening the rear hood, we have access to two charging connectors and micro USB port for robot programming.

The DC motors are powered directly from battery with the PWM constraint such that the maximum voltage can not exceed 6V. Other electronic components are powered through the step-down voltage regulator D24V22F5 lowering the voltage from 7.4V to 5V. These regulator have built-in short-circuit protection, reverse-voltage protection, overheating protection (a thermal shutdown feature) and soft-start feature for the reduction of inrush current.
