Building Instructions -

• LEGO MINDSTORMS EV3

This robot is a spin-off of the Useless machine built from LEGO Mindstorms EV3. This robots mission is to be the last to press the button it holds.

Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.

The attachment is constructed from LEGO Mindstorms EV3 sets.

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.

It kind of looks like an Inuit. But it surely walks like one. Most of the time Inuit walk with special boots that allows them to walk on deep snow without getting stuck. This robot walks in the same way. It has large feet and it moves one after the other. 

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.  

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. 

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. 

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

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. 

This is the attachment of Team "Nightbeast", with which they solve M01 and M02 from FLL Into Orbit Challenge
