The cutest robot in the classroom!
WALL-EV3 is shaped after Disney Pixar's WALL·E (Waste Allocation Load Lifter – Earth-Class), a fictional trash compactor robot left back on Earth to clean the planet from garbage, in a not-so-distant super-consumistic future.
WALL-EV3 is built out of a single LEGO MINDSTORMS Education EV3 set 45544.
WALL-EV3 has two triangular shaped treads driven by two EV3 Large Motors, and rotating head and arms driven by the EV3 Medium Motor. The EV3 gyro sensor allows the robot to drive perfectly straight, and turn precisely, even if the treads slip when travelling on uneven ground. It's easy to attach an EV3 Color Sensor looking down on the ground, to enable WALL-EV3 to follow a line. Thanks to the EV3 Ultrasonic Sensor, WALL-EV3 can navigate while avoiding obstacles, or can follow your hand.
