Sumo robotics is a very popular category, not only in LEGO robotics but also in non-LEGO robotics! The rules are simple: two robots start on a circular mat, and the first robot to be pushed out of the circle loses! You can also lose if your robot stops moving. The judge can declare a draw if the two robots are locked together for a long time. Good luck!

Construction and Theory

In this lesson, you will have the opportunity to design your own LEGO Sumo robot! Usually, in a competition, there are strict rules about the size and weight of the robot as these factors make a huge difference in fights. We will take a more relaxed approach; you can build anything as long as everyone has fun!

For your information, here are some example rules: the size of your robot is usually limited to 20x20 square centimeters, with weight categories of 500g, 1kg, and 3kg!

Build your own Sumo robot! Think of different strategies. How will your robot push other robots out of the field? What does it need?

After building the robot, close the box to keep the desk clear.

  1. Gather all the parts from the desk and put them back in the box.
  2. Close the box and move it aside so it's out of your way.

Programming and Theory

The programming today is also relatively open-ended. There are many strategies you can use in sumo battles. What will your strategy be? Let's first ensure your robot can move forward, and then we can continue with your chosen strategy!

Program your robot to move forward indefinitely.

Try to have a sumo battle against another robot.

Bonus Tasks

These tasks are optional and can only be solved by students who have completed all the main tasks and received confirmation from their teacher.

Program a new strategy and try to compete again.

Try to improve your robot! Maybe you can add a new part or enhance the program?
