• EV3-G

Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3

This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example. 

The attachment was used during FIRST LEGO League 2014 Robotics competition.

This attachment is accomplishing three missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot

These are the official robot rules for the FIRST LEGO League Hydrodynamics 2017-2018 robot missions. 

Background

Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.

Mission

Get the lander to one of its targets intact, or at least get it to base.

Scores

• Move the lander to be intact, touching the mat, and completely in its target circle: 22 OR
• Move the lander to be intact, touching the mat, and completely in the northeast planet area: 20 OR
• Move both parts of the lander completely into the base: 16
• Possible scores: 0, 16, 20, 22

Scoring Requirements

• The result must be visible at the end of the match.
• The lander is “intact” if its parts are connected by at least two of its four tan location axles.

This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.  

Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.

SIngle robot attachment, many points. 

These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments. 

Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.

This is an attachment for the Kriket box robot. It demonstrates how to build attachments that glide over the robot, are pinless and could be quickly and easily replaced and changed with another attachment. This attachment also lifts. Quite cool. Quite cool.

These are 3D Building Instructions for the Theater Scene Change mission model for the FIRST LEGO League 2023-2024 MASTERPIECE competition.

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.

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. 

These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.
