Getting Started

In these first few projects, you’ll learn the basics of simulation using the EV3 programming environment. The projects are grouped so that each successive project introduces a new skill or sensor.

Line Follower

Follow the black line to navigate through a maze. Watch out for obstacles!

Robot Vacuum

Someone has made an awful mess in here! With all of these bricks scattered across the floor, it's really only a matter of time before someone steps on one. Can you write a program to vacuum it all up?

Cleanup Challenge

Knock down the tower and clean all of the parts off of this mat. Do it as quickly as possible, but be careful. Don't fall off!

Competitive / Multiplayer

With the basic projects mastered, why not try your hand at one of the multi-robot challenges? Compete against yourself or a friend and run multiple programs simultaneously.


Engage in two-robot soccer! Use both the infrared and compass sensors and write a program that locates the ball and net.


Are you the king of the ring? Push your opponent out to find out.

Multiplayer Sweep

It takes two! Knock down the tower and capture all of the pieces from the mat before your opponent does.

World Robot Olympiad

The World Robot Olympiad brings together young people from all over the world to develop their creativity and problem solving skills through challenging and educational robotics competitions. This year's theme, "Robot Explorers", encourages students to build robots that can investigate and explore different environments, some of them hostile to humans.

Pearl Diving

In Pearl Diving, players must build a robot that can dive and explore under the sea for pearls. For each dive you only have 30 seconds before the robot needs to come back up for air.

Treasure Hunt

Players are challenged to build a robot that is tasked with collecting 5 artifacts in an unknown environment. In some cases, this environment will contain artifacts that are harmful to the explorer that should be left undisturbed.


Players are challenged to build a robot that is tasked with collecting supplies and delivering them to outposts high in the mountains. Clues are available regarding the environment, and the location of each of the supplies to collect. The closer you get the supplies to the drop location, the higher the points.


With over 25,000 teams in 80 countries, FIRST® LEGO® League is one of the largest robotics competitions. Every year, a new challenge is revealed that encourages you to build and program your own LEGO® robots to achieve maximum points in minimal time.

Trash Trek Challenge 2015

One man's trash is another man's treasure! Identify the different kinds of trash, Select a problem with the way it's handled, Design a solution to fix it and spread the word to win the 2015 challenge. Waste less and Recycle everywhere!
