Fint, a LEGO Mindstorms EV3 goalkeeper robot
Do you have a friend for a sleepover? This might be the perfect robot for you! It is a football gate, guarded by Fint, the goalkeeper robot. You can control him, by using the remote controller, that consists of two Touch Sensors. Take turns making penalty shots and have a blast with this awesome robot!
What we recommend:
- Using a big LEGO wheel from your set as a football ball.
- If you throw the wheel too fast for the robot to catch, increase the distance between the place you shoot the ball from and the robot.

Pinless Attachment for LEGO Mindstorms Robots
Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions.

WRO 2021 Junior: Slaimi - a post season WRO competition solution robot
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
