Playing Football with robots is extremely fun. It could be part of the classes, it could be part of demonstration days. This is the goal keeper.
This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.
This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears
PID is the most popular method for programming line-following robots. It’s a bit complex, so this tutorial is longer, as we’ll break it down into steps and explain each element of the equation.
This approach to programming line-following robots is not ideal for beginners. Attempting to learn this as a first step in competition preparation may give a misleading impression of the competition's complexity and could discourage students from learning the necessary skills to compete in this category.

Then the problem lies in other external factors.

A LEGO Mindstorms EV3 Chassis with wheels at the front. Built with the EV3 set you can use this robot chassis as a base for extending with attachments.
Building instructions for the robot build with LEGO Mindstorms EV3. It is called "Frankenstein" because the two motors are in two different directions.

Note: This robot contains wheels that are from the NXT set.
Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3
This is a ping-ball containing attachment for a World Robotics Olympiad. The attachment is building with LEGO Mindstorms EV3 parts. It is tiltel so that it is easier for the balls to fall off at certain points, which was part of the missions at the 2015 cmpetition.
This is one of the robots used in World Robotics Olympiad. It uses chains to move ping pong balls out of a container.
LEGO Mindstorms Robot Base for a high placed attachment for containing ping pong balls. It is interesting how the balance is achieved with such an attachment. It was only one of the version in a series of LEGO Mindstorms Robots for World Robotics Olympiad.
