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.
It is amazingly expensive to send heavy stuff like construction material into space, so scientists and engineers are instead learning how to print what they need in space, using available extraterrestrial elements.
The robot needs to get a regolith core sample and place it into the 3D printer, which will cause the 2 × 4 brick to pop out. The ejected 2 × 4 brick can then be delivered elsewhere for more points.

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.
A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.
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.
Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3
Мотивиран от петминутния робот, този робот си има собствени релси!
Това е още един ЛЕГО Майндстормс хващач, но този път той има 4 пръста! Те се движат едновременно с помощта на среден мотор. Този хващач е взет от Крон - Лего кран.
These are the official robot rules for the FIRST LEGO League Hydrodynamics 2017-2018 robot missions.
Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.
Get the lander to one of its targets intact, or at least get it to base.

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.
Това е робот, направен да повдига чаша, докато я държи изправена! Той използва един голям EV3 мотор, закачен за брика, за да повдига чашата на всеки ъгъл, който искате! Чашата, която ние сме ви дали е изцяло за красота, но с няколко корекции, робота може да повдига и истински чаши! Все пак внимавайте около течности!
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:
This is a very funny robotics hand that you could place on your hand and control with your fingers. Actually quite funny to point at things, to move the three fingers. There are also many things to learn from the gears and its constructions.
It is true that it requires a lot of parts, but its worth it.
