This FIRST Lego League (FLL) Mindstorms EV3 robot platform sports two auxiliary motors out front -- an EV3 Medium Motor down low and a fixed EV3 Large Motor a bit higher. Two EV3 Color Sensors allow for good Line Following and Line Squaring capabilities. The flat front and rear bumpers accommodate squaring-up against the walls of the FLL robot game field. An EV3 Gyro Sensor is on the side to enable accurate turns. For clarity, the EV3 Connector Cables are not shown; you will need seven of them (for 4 motors + 3 sensors).
