Reusable LEGO Geared Attachment 2
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 construction is taken from here. It is a little bit modified so you can build it from one EV3 Set. We made it because we thing it is genius. We are "angry" in the good meaning оf the word, because we didn't invent it. We hope that you will have the same fun as we do with it.
We think that this thing is a perfect example of balancing and mind scratching behavior. You also need to be precise with the length of the ropes. And the best part of it is that you don't need to program anything.
Have fun and good luck!
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.
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.
Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3
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.
Motivated by the five-minute robot, this robot has its own rails!
This is another LEGO Mindstorms grabber, but this time it has 4 fingers! They are moved simultaneously by a medium motor. The grabber was taken from Cron - LEGO Mindstorms EV3 Crane.

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.
This is a robot, designed to easily lift a cup, while still holding it upright. The robot uses one motor attached to the brick to lift the cup to any angle you want. The cup we have added is purely cosmetic, but with a few adjustments, you can make it lift real cups. Be careful around liquids though!
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:
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 is a very funny robotics hand with 3 fingers that you could put on your hand to "Rule the World". It's funny to control it with the touch sensors.
Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here.
Together the controller and the car look like this:
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 attachment accomplishes the Into Orbit Extraction mission from the FIRST LEGO League Into Orbit 2017-2018 competitions. The based of the robot is the SUV Competition Box Robot from LEGO Mindstorms EV3.

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