This robot has a 3D printed chassis. It has an arduino uno for the brains, continous rotation servos for motion, a AA battery pack to power the servos, a Lithium Ion battery and charging/boost circuit (in the form of a shield) to power the arduino, a PWM shield to drive the servos, and finally, sensors that allow it to either follow a line or drive around a table without falling off!
